Changelog:

  - bsnes: cheat code “enabled” option changed to “enable”
  - bsnes: connected “Cancel” action on add/edit cheat code window
  - hiro: improved BrowserDialog::selectFolder() behavior
      - can choose “Select” inside of a target folder when no items are
        selected
  - bsnes: implemented state manager
  - bsnes: save a recovery state before loading a state, quitting, or
    changing drivers
  - bsnes: input settings, hotkey settings, cheat editor, state manager
    entries are now batchable
      - this allows bulk clearing/deleting of entries
  - bsnes: cheat code list now auto-sorts alphabetically instead of
    using up/down move arrows

I know most people will probably prefer to order cheat codes the way
they want, but the issue is that the state manager can't really work
this way. Each state is a file on disk. So yes, we could store a
states-manifest.bml to track the order of the states, or try to insert
numbers into the filenames and do bulk filesystem rename operations on
sorting, but then we would run into oddities when users delete state
files manually. And really, manual sorting is just clumsy. If you really
want a specific ordering, you can prefix cheats/states with numeric
indices instead.

Changelog:

  - nall: renamed array to adaptive_array; marked it as deprecated
  - nall: created new array class; which is properly static (ala
    std::array) with optional bounds-checking
  - sfc/ppu-fast: converted unmanaged arrays to use nall/array (no speed
    penalty)
  - bsnes: rewrote the cheat code editor to a new design
  - nall: string class can stringify pointer types directly now, so
    pointer() was removed
  - nall: added array_view and pointer types (still unsure if/how I'll
    use pointer)

Changelog:

  - nall/GNUmakefile: added `openmp=(true,false)` option; can be toggled
    when building higan/bsnes
      - defaults to disabled on macOS, because Xcode doesn't stupidly
        doesn't ship with support for it
  - higan/GNUmakefile: forgot to switch target,profile back from
    bsnes,fast to higan,accurate
      - this is just gonna happen from time to time, sorry
  - sfc/dsp: when using the fast profile, the DSP syncs per sample
    instead of per clock
      - should only negatively impact Koushien 2, but is a fairly
        significant speedup otherwise
  - sfc/ppc,ppu-fast: optimized the code a bit (ppu 130fps to 133fps)
  - sfc/ppu-fast: basic vertical mosaic support (not accurate, but
    should look okay hopefully)
  - sfc/ppu-fast: added missing mode7 hflip support
  - sfc/ppu-fast: added support to render at 256-width and/or 240-height
      - gives a decent speed boost, and also allows all of the older
        quark shaders to work nicely again
      - it does violate the contract of Emulator::Interface, but oh
        well, it works fine in the bsnes GUI
  - sfc/ppu-fast: use cached CGRAM values for mode7 and sprites
  - sfc/ppu-fast: use global range/time over flags in object rendering
      - may not actually work as we intended since it's a race condition
        even if it's only ORing the flags
      - really don't want to have to make those variables atomic if I
        don't have to
  - sfc/ppu-fast: should fully support interlace and overscan modes now
  - hiro/cocoa: updated macOS Gatekeeper disable support to work on
    10.13+
  - ruby: forgot to fix macOS input driver, sorry
  - nall/GNUmakefile: if uname is present, then just default to rm
    instead of del (fixes Msys)

Note: blur emulation option will break pretty badly in 256x240 output
mode. I'll fix it later.

I really wanted to work on the new PPU today, but I thought I'd spend a
few minutes making some minor improvements to nall::memory, that was
five and a half hours ago. Now I have a 67KiB diff of changes. Sigh.

Tim Allen 2b8df2e70e Update to v106r27 release.
byuu says:

Changelog:

  - nall: merged Path::config() and Path::local() to Path::userData()
      - ~/.local/share or %appdata or ~/Library/ApplicationSupport
  - higan, bsnes: render main window icon onto viewport instead of
    canvas
      - should hopefully fix a brief flickering glitch that appears on
        Windows
  - icarus: improved Super Famicom heuristics for Starfox / Starwing RAM
  - ruby/Direct3D: handle viewport size changes in lock() instead of
    output()
      - fixes icon disappearing when resizing main window
  - hiro/Windows: remove WS_DISABLED from StatusBar to fix window
    resize grip
      - this is experimental: I initially used WS_DISABLED to work
        around a focus bug
      - yet trying things now, said bug seems(?) to have gone away at
        some point ...
  - bsnes: added advanced settings panel with real-time driver change
    support

I'd like feedback on the real-time driver change, for possible
consideration into adding this to higan as well.

Some drivers just crash, it's a fact of life. The ASIO driver in
particular likes to crash inside the driver itself, without any error
messages ever returned to try and catch.

When you try to change a driver with a game loaded, it gives you a scary
warning, asking if you want to proceed.

When you change a driver, it sets a crash flag, and if the driver
crashes while initializing, then restarting bsnes will disable the
errant driver. If it fails in a recoverable way, then it sets the driver
to “None” and warns you that the driver cannot be used.

What I'm thinking of further adding is to call emulator→save() to
write out the save RAM contents beforehand (although the periodic
auto-saving RAM will handle this anyway when it's enabled), and possibly
it might be wise to capture an emulator save state, although those can't
be taken without advancing the emulator to the next frame, so that might
not be a good idea.

I'm also thinking we should show some kind of message somewhere when a
driver is set to “None”. The status bar can be hidden, so perhaps on the
title bar? Or maybe just a warning on startup that a driver is set to
“None”.

Tim Allen 8bbbc5e737 Update to v106r21 release.
byuu says:

Changelog:

  - higan: target-tomoko has been renamed to target-higan
  - Super Famicom: event has been renamed to
    processor(architecture=uPD78214)
  - Super Famicom: SNES-EVENT supported once more; under board IDs
    EVENT-CC92 and EVENT-PF94
  - Super Famicom: SNES-EVENT preliminarily set up to use DIP switch
    settings ala the Nintendo Super System (incomplete)
  - Super Famicom: MCC PSRAM moved inside the MCU, as it is remappable
  - Super Famicom: MCC emulation rewritten from scratch; it is now
    vastly more accurate than before
  - Super Famicom: added BSC-1A5B9P-01 board definition to database;
    corrected BS-MCC-RAM board definition
  - Super Famicom: moved SHVC-LN3B-01 RAM outside of
    processor(identifier=SDD1)
  - higan: when selecting a default game to load for a new system entry,
    it will change the system option to match the media type
  - higan: the load text box on the system entry window is now editable;
    can be used to erase entries
  - icarus: fixed bug in Famicom importing
  - icarus: importing unappended SNES coprocessor firmware will now
    rename the firmware properly
  - hiro/GTK,Qt: WM_CLASS is now set correctly in `argv[0]`, so
    applications should show “higan”, “icarus” instead of “hiro” now

Note: if you wish to run the BS-X town cartridge, the database currently
lists the download RAM as type “PSRAM”. This needs to be changed to
“RAM” in order to load properly. Otherwise, the emulator will bomb
out on the load window, because BSC-1A5B9P-01 expects PSRAM to always be
present, but it won't find it with the wrong memory type. I'll correct
this in the database in a later release. For now, you can copy the game
portion of the manifest to a new manifest.bml file and drop it into the
gamepak folder until I fix the database.

Tim Allen 8023d9cbe8 Update to v106r15 release.
byuu says:

Changelog:

  - main menu renamed again (Library→System→Systems)
  - the 'Hidden' checkbox on system properties was moved to the main
    list as a 'Show' checkbox instead
  - the move up/move down buttons on the systems panel now function
  - added icons to indicate 'system' versus 'game boot' entries in the
    systems list

I still didn't add ComboEdit to the Windows hiro port, so once again
this will be Linux/BSD only.

I polished the browse button for selecting a boot game. It'll use a list
of all bootable media file extensions, so that if you double-click any
supported game, it'll select it instead of going inside the folder. If
you pick a non-bootable folder, like say a Sufami Turbo cartridge, it
will go inside the folder instead, because it will treat it like any
other regular folder.

Having a checkbox next to text in the same cell doesn't work so well on
lists that have an onActivate action. Say you tried to double-click the
“Name” field on the Systems tab, it would toggle the checkbox twice
before popping open the system properties editor window. So because of
this, I made the show checkbox its own column. And for consistency, I
did the same for the slot# on the cheat editor window.

As a bit of really pedantic polish: if there are no systems enabled,
then the main menu won't show the separator before the “Load ROM Image”
option anymore.

I think something is wrong with the Markup::Node::insert syntax, but I
realized I have Markup::Node::swap, and just used that for the up/down
arrows on the systems panel for now. But we should probably fix insert()
at some point ... sigh.

Tim Allen 0ea17abfea Update to v106r15 release.
byuu says:

Changelog:

  - Super Game Boy: fixed loading of boot ROM
  - hiro: added ComboEdit::setEditable(bool = true);
  - tomoko: added new systems settings panel

Note!!: this release will not compile on Windows or macOS due to the
missing ComboEdit control! I'll try to merge in hex's implementation
for the Windows release here soon. macOS users will probably be out of
luck for a while, sorry.

The new systems panel is an idea I've been meaning to implement for
quite a while, but finally got around to starting on it. It's still
fairly unpolished, but the basic idea is there for Linux/BSD users to
try out now.

So imagine the Super Game Boy, BS-X Satellaview, Sufami Turbo, and the
associated BS Memory Pack-slotted SNES cartridges. To play any of those,
you needed to choose Nintendo→Super Famicom, and then select the
relevant cartridge, and then select any slotted cartridges to play with
it.

This was acceptable-ish, if not ideal. But now imagine in the future if
we wanted to support the Famicom Disk System, which is technically a
cartridge that plugs into the Famicom deck. Or the PC Engine CD, which
has one of three special HuCards that must be inserted (ignoring the
Turbo Duo where it's built-in—I'm going to be emulating the Super CD
as if you're using a stock PCE CD.) Or the Mega CD, where there are
probably a half dozen or more BIOS + hardware revisions that are
region-specific, which connect to an expansion port that is identical to
the cartridge port save for the Mega Drive seeing an I/O register bit
toggled here.

In all of these cases, it's going to be a real pain to have to choose
the 'BIOS' every time you want to play a game for them.

I can't distribute these BIOSes with higan due to copyright
restrictions, and trying to ship dummy folders for every possible
combination would become quite odious, and difficult for people to use
(compare to setting up the Game Boy Advance system BIOS.)

And so I've created the new systems settings panel. Here, you can manage
a list of systems that show up under the higan library menu (now renamed
to “System”), where each entry contains name, boot, and hidden
parameters.

The name parameter is what shows up in the system menu. You can call any
system higan emulates whatever you like here. Don't like “Super
Famicom”? Change it to “SNES”, then.

The boot parameter is a combo edit with a dropdown for all of the
systems higan emulates. If you choose one of these, then the higan
system menu option will work exactly like in previous releases, and
prompt you for a cartridge. But if you choose the browse button next to
the combo edit control, you'll get to pick any gamepak from the higan
library of your choosing.

So you could choose the SGB2 BIOS, and name the menu option “Super Game
Boy 2”, and when you choose the menu option, it will load the SFC core,
load the SGB2 BIOS, and only prompt you for the Game Boy game you wish
to play on it. The same deal goes for the FDS, PCE-CD, Mega CD, Mega
Drive Sonic & Knuckles lock-on cartridge, BS-X Satellaview, SD Gundam
G-Next, etc. Whatever you want to be in the menu, you can put in there
by pointing higan at the appropriate 'BIOS' gamepak to load.

Astute readers have probably already noticed, but you can technically
use this on non-slotted games as well, thus creating instant boot
options for your absolute favorite games, if you so wanted. Point it at
Zelda 3, and you can boot it instantly from the main menu, without any
need for file selection.

The hidden option is a way to hide the system entries from the system
menu. Primarily this would be a fast way for users to disable emulation
cores they never use in higan, without having to remove the options.

The major concession with this change is the collapsing of the
per-manufacturer submenus. What this means is you will now have all
twelve higan emulated systems in the main menu by default. This makes
the list rather long, but ... oh well. I may try to offer some form of
grouping in the future, but the grouping defeats the “list order =
display order” design, and I'm not willing to auto-sort the list. I want
people to be able to control the ordering of the system menu, and have
added (as yet non-functional) sorting arrows for that purpose. I also
don't have a combined tree+table view widget in higan to try to and
group things. But ... we'll see how things go in the future.

Another idea is to add a specialty load option that opens up the user's
Emulation library path, and lets you pick a gamepak for any system,
which would boot the same way as when you drop a gamepak onto the higan
executable or main window. So say you almost never play Wonderswan
games, this would be a way to play them without them cluttering your
system menu list.

The “import ROM files” option has been removed. All it does is launch
icarus directly. I would rather users become familiar with using icarus.
The “load ROM file” option remains.

Anyway, this is all still a work in progress, so please give it time and
don't overload me with too many suggested changes right now, thanks :3

Changelog:

  - manifest: memory/battery now resides under type at
    memory/type/battery
  - genius: volatile option changed to battery; auto-disables when not
    RAM or RTC type
  - higan: added new Emulator::Game class to parse manifests for all
    emulated systems consistently
  - Super Famicom: board manifest appended to manifest viewer now
  - Super Famicom: cartridge class updated to use Emulator::Game objects
  - hiro: improve suppression of userland callbacks once
    Application::quit() is called
      - this fixes a crash in genius when closing the window with a tree
        view item selected

My intention is to remove Emulator::Interface::sha256(), as it's not
really useful. They'll be removed from save states as well. I never
bothered validating the SHA256 within them, because that'd be really
annoying for ROM hackers.

I also intend to rename Emulator::Interface::title() to label() instead.

Most everything is still broken. The SNES still needs all the board
definitions updated, all the other cores need to move to using
Emulator::Game.

Tim Allen e216912ca3 Update to v106r09 release.
byuu says:

Changelog:

  - higan, icarus, genius: new manifest syntax (work in progress)

Pretty much only LoROM and HiROM SNES games will load right now, and RAM
will only work right if the save.ram file already exists to pull its
file size from (a temporary cheap hack was used.)

Basically, I'm just getting this out there for evaluation.

One minor errata is that I switched icarus to using “memory/battery” to
indicate battery-backed RAM, whereas genius still uses “memory/volatile”
to indicate non-battery-backed RAM.

I intend to make it “memory/battery” in genius, and have the field
auto-enable when RAM or RTC is selected for type (obviously allowing it
to be unchecked for volatile memory.)

I need to update all 64 production boards, and 25 of 29 generic boards,
to use the new slot syntax; and I also need to update every single core
in higan to use the new manifest game syntax. I want to build out a
generic manifest game parser that all emulation cores will use.

Once I finish this, I'll also need to write a database converter to
update all of my licensed game dumps to the new database syntax.

I also need to write up something for doc.byuu.org explaining the new
manifest game syntax. The manifest board syntax will still be “internal”
and subject to revisions, but once v107 is out, the gamepak manifest
format will be set in stone sans extensions.

Tim Allen 2f81b5a3e7 Update to v106r2 release.
byuu says:

Changelog:

  - Super Famicom: added support for loading manifests without embedded
    mapping information¹
  - genius: initial commit
  - various Makefile cleanups

¹: so the idea here is to try and aim for a stable manifest format,
and to allow direct transposition of icarus/genius database entries into
manifest files. The exact mechanics of how this is going to work is
currently in flux, but we'll get there.

For right now, `Super Famicom.sys` gains `boards.bml`, which is the raw
database from my board-editor tool, and higan itself tries to load
`boards.bml`, match an entry to game/board from the game's `manifest.bml`
file, and then transform it into the format currently used by higan. It
does this only when the game's `manifest.bml` file lacks a board node.
When such a board node exists, it works as previous versions of higan
did.

The only incompatible change right now is information/title is now
located at game/label. I may transition window title display to just use
the filenames instead.

Longer term, some thought is going to need to go into the format of the
`boards.bml` database itself, and at which point in the process I should
be transforming things.

Give it time, we'll refine this into something nicer.

Changelog:

  - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode
    names with descriptive names
  - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS`
  - icarus: added `Icarus::missing() -> string_vector` to list missing
    appended firmware files by name
  - ruby, hiro: fix macosx→macos references

The processor instruction renaming was really about consistency with the
other processor cores. I may still need to do this for one or two more
processors.

The icarus change should allow a future release of the icarus
application to import games with external SNES coprocessor firmware once
again. It will also allow this to be possible when used in library mode.

        undocumented functions ... fun

The goal with this WIP was basically to prepare hiro for potential
automatic scaling. It'll be extremely difficult, but I'm convinced that
it must be possible if macOS can do it.

By moving from signed integers to floats for coordinates, we can now
scale and unscale without losing precision. That of course isn't the
hard part, though. The hard part is where and how to do the scaling. In
the ideal application, hiro/core and hiro/extension will handle 100% of
this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
of what's going on, but ... to even make that possible, things will need
to change in every per-platform core, eg the per-platform code will have
to call a core function to change geometry, which will know about the
scaling and unscale the values back down again.

Gonna be a lot of work, but ... it's a start.

¹: The observation that this mapper split $4000-7fff into two banks
came from MAME's implementation. But their implementation was quite
broken and incomplete, so I didn't actually use any of it. The
observation that this mapper split $a000-bfff into two banks came from
Tauwasser, and I did directly use that information, plus the knowledge
that $0400/$0800 are the RAM bank select registers.

The text corruption is due to a race condition with timing. The game is
transferring font letters via HDMA, but the game code ends up setting
the bank# with the font a bit too late after the HDMA has already
occurred. I'm not sure how to fix this ... as a whole, I assumed my Game
Boy timing was pretty good, but apparently it's not that good.

²: The entire design of this mapper comes from endrift's notes.
endrift gets full credit for higan being able to emulate this mapper.
Note that the accelerometer implementation is still not tested, and
probably won't work right until I tweak the sensitivity a lot.

³: So the fun part of this is ... it breaks the strict 60fps rate of
the Game Boy. This was always inevitable: certain timing conditions can
stretch frames, too. But this is pretty much an absolute deal breaker
for something like Vsync timing. This pretty much requires adaptive sync
to run well without audio stuttering during the transition.

There's currently one very important detail missing: when the LCD is
turned off, presumably the image on the screen fades to white. I do not
know how long this process takes, or how to really go about emulating
it. Right now as an incomplete patch, I'm simply leaving the last
displayed image on the screen until the LCD is turned on again. But I
will have to output white, as well as add code to break out of the
emulation loop periodically when the LCD is left off eg indefinitely, or
bad things would happen. I'll work something out and then implement.

Another detail is I'm not sure how long it takes for the LCD to start
rendering again once enabled. Right now, it's immediate. I've heard it's
as long as 1/60th of a second, but that really seems incredibly
excessive? I'd like to know at least a reasonably well-supported
estimate before I implement that.

  - icarus: enhance Game Boy heuristics³
  - nall: fix three missing return statements [Jonas Quinn]
  - ruby: hopefully fixed all compilation errors reported by Screwtape
    et al⁴

¹: because there's no concept of a controller for cartridge inputs,
I'm attaching to the base platform for now. An idea I had was to make
separate ports for each cartridge type ... but this would duplicate the
rumble input between MBC5 and MBC7. And would also be less discoverable.
But it would be more clean in that users wouldn't think the Game Boy
hardware had this functionality. I'll think about it.

²: it probably won't work yet. Rumble isn't documented anywhere, but
I dug through an emulator named GEST and discovered that it seems to use
bit 3 of the RAM bank select to be rumble. I don't know if it sets the
bit for rumbling, then clears when finished, or if it sets it and then
after a few milliseconds it stops rumbling. I couldn't test on my
FreeBSD box because SDL 1.2 doesn't support rumble, udev doesn't exist
on FreeBSD, and nobody has ever posted any working code for how to use
evdev (or whatever it's called) on FreeBSD.

³: I'm still thinking about specifying the MBC7 RAM as EEPROM, since
it's not really static RAM.

⁴: if possible, please test all drivers if you can. I want to ensure
they're all working. Especially let me know if the following work:
macOS: input.carbon Linux: audio.pulseaudiosimple, audio.ao (libao)

If I can confirm these are working, I'm going to then remove them from
being included with stock higan builds.

I'm also considering dropping SDL video on Linux/BSD. XShm is much
faster and supports blurring. I may also drop SDL input on Linux, since
udev works better. That will free a dependency on SDL 1.2 for building
higan. FreeBSD is still going to need it for joypad support, however.

      - only took eight months! :D

¹: When I tried to move the Master System hardware port below the
controller ports, I ran into a world of pain.

The input settings list expects every item in the
`InputEmulator<InputPort<InputDevice<InputMapping>>>>` arrays to be
populated with valid results. But these would be sparsely populated
based on the port and device IDs from inside higan. And that is done so
that the Interface::inputPoll can have O(1) lookup of ports and devices.
This worked because all the port and device IDs were sequential (they
left no gaps in the maps upon creating the lists.)

Unfortunately by changing the expectation of port ID to how it appears
in the list, inputs would not poll correctly. By leaving them alone and
just moving Hardware to the third position, the Game Gear would be
missing port IDs of 0 and 1 (the controller ports of the Master System).
Even by trying to make separate MasterSystemHardware and
GameGearHardware ports, things still fractured when the devices were no
longer contigious.

I got pretty sick of this and just decided to give up on O(1)
port/device lookup, and moved to O(n) lookup. It only knocked the
framerate down by maybe one frame per second, enough to be in the margin
of error. Inputs aren't polled *that* often for loops that usually
terminate after 1-2 cycles to be too detrimental to performance.

So the new input system now allows non-sequential port and device IDs.

Remember that I killed input IDs a while back. There's never any reason
for those to need IDs ... it was easier to just order the inputs in the
order you want to see them in the user interface. So the input lookup is
still O(1). Only now, everything's safer and I return a
maybe<InputMapping&>, and won't crash out the program trying to use a
mapping that isn't found for some reason.

Errata: the escape key isn't working on the browser/message dialogs on
Windows, because of course nothing can ever just be easy and work for
me. If anyone else wouldn't mind looking into that, I'd greatly
appreciate it.

Having the `WM_KEYDOWN` test inside the main `Application_sharedProc`, it
seems to not respond to the escape key on modal dialogs. If I put the
`WM_KEYDOWN` test in the main window proc, then it doesn't seem to get
called for `VK_ESCAPE` at all, and doesn't get called period for modal
windows. So I'm at a loss and it's past 4AM here >_>

Changelog:

  - tomoko: removed "Settings→Video Emulation→Overscan Mask" setting¹
  - tomoko: remove a few unnecessary calls to resizeViewport on startup
  - tomoko: only resize main window from video settings when in adaptive
    or toggling adaptive mode²
  - hiro/windows: add `SWP_NOACTIVATE` flag to prevent focus stealing on
    resizing invisible windows³
  - hiro/windows: suppress spurious API-generated `onSize()` callback
    when calling `setVisible()`

¹: it just seemed like bad design to default to overscan masking
being disabled with overscan masks of 8 horizontal, 8 vertical out of
the box. Users would adjust the sliders and not see anything happening.
Instead, I've set the default masks to zero. If you want to turn off
overscan masking, simply slide those to zero again.

²: I figure the only way we're going to be able to fairly evaluate
Screwtape's suggestion is to try it both ways. And I will admit, I kind
of like the way this works as well ... a lot more so than I thought I
would, so I think it was a great suggestion. Still, now's the time if
people have strong opinions on this. Be sure to try both r10 and r11 to
compare. Barring no other feedback, I'm going to keep it this way.

³: this fixes the blinking of the main window on startup.

Screwtape, thanks again for the improvement suggestions. At this point
though, I am not using a tiling window manager. If you are able to patch
hiro/gtk and/or hiro/qt (I mostly use GTK) to work with tiling window
managers better, I wouldn't mind applying said patches, so long as they
don't break things on my own Xfce desktop with xfwm4.

Also, I noticed one issue with Xfce ... if the window is maximized and I
try to call `Window::setSize()`, it's not actually removing the maximize
flag. We'll need to look into how to add that to GTK, but I don't think
it's a huge issue. A similar glitch happens on windows where the icon
still reflects being maximized, but it does actually shrink, it just
sticks to the top left corner of the screen. So this isn't really a
critical bug, but would be extra polish.

  - fc: improved PAL mode timing; use PAL APU timing tables; fix PAL
    noise period table [hex\_usr]
  - md: support aborting a Z80 bus wait in order to capture save states
    without freezing
      - note that this will violate accuracy; but in practice a slight
        desync is better than an emulator deadlock
  - sfc: revert DSP ENDX randomization for now (want to research it more
    before deploying in an official release)
  - sfc: fix Super Famicom.sys/manifest.bml APU RAM size [hex\_usr]
  - tomoko: cleaned up make install rules
  - hiro/cocoa: use ABGR for pixel data [Sintendo]

Note: I forgot to change the command-line and drag-and-drop separator
from : to | in this WIP. However, it is corrected in the v103 official
binary and source published on download.byuu.org. Sorry about that, I
know it makes the Git repository history more difficult. I'm not
concerned whether the : → | change is part of v103 or v103r01 in the
repository, and will leave this to your discretion, Screwtape.

I also still need to set the VDP bit to indicate PAL mode in the Mega

The last one sure ended in failure. The plan was to put a region
dropdown directly onto hiro::BrowserDialog, and I had all the code for
it working. But I forgot one important detail: the system loads
cartridges AFTER powering on, so even though I could technically change
the system region post-boot, I'd rather not do so.

So that means we have to know what region we want before we even select
a game. Shit.

  - libco: added macOS-specific section marker [Ryphecha]

So ... the major news this time is the removal of the soft reset
behavior. This is a major!! change that results in a 100KiB diff file,
and it's very prone to accidental mistakes!! If anyone is up for
testing, or even better -- looking over the code changes between v102r01
and v102r02 and looking for any issues, please do so. Ideally we'll want
to test every NES mapper type and every SNES coprocessor type by loading
said games and power cycling to make sure the games are all cleanly
resetting. It's too big of a change for me to cover there not being any
issues on my own, but this is truly critical code, so yeah ... please
help if you can.

We technically lose a bit of hardware documentation here. The soft reset
events do all kinds of interesting things in all kinds of different
chips -- or at least they do on the SNES. This is obviously not ideal.
But in the process of removing these portions of code, I found a few
mistakes I had made previously. It simplifies resetting the system state
a lot when not trying to have all the power() functions call the reset()
functions to share partial functionality.

In the future, the goal will be to come up with a way to add back in the
soft reset behavior via keyboard binding as with the Master System core.
What's going to have to happen is that the key binding will have to send
a "reset pulse" to every emulated chip, and those chips are going to
have to act independently to power() instead of reusing functionality.
We'll get there eventually, but there's many things of vastly greater
importance to work on right now, so it'll be a while. The information
isn't lost ... we'll just have to pull it out of v102 when we are ready.

Note that I left the SNES reset vector simulation code in, even though
it's not possible to trigger, for the time being.

Also ... the Super Game Boy core is still disconnected. To be honest, it
totally slipped my mind when I released v102 that it wasn't connected
again yet. This one's going to be pretty tricky to be honest. I'm
thinking about making a third GameBoy::Interface class just for SGB, and
coming up with some way of bypassing platform-> calls when in this
mode.

2016-10-28 08:16:58 +11:00
Tim Allen 427bac3011 Update to v101r06 release.
byuu says:

I reworked the video sizing code. Ended up wasting five fucking hours
fighting GTK. When you call `gtk_widget_set_size_request`, it doesn't
actually happen then. This is kind of a big deal because when I then go
to draw onto the viewport, the actual viewport child window is still the
old size, so the image gets distorted. It recovers in a frame or so with
emulation, but if we were to put a still image on there, it would stay
distorted.

The first thought is, `while(gtk_events_pending())
gtk_main_iteration_do(false);` right after the `set_size_request`. But
nope, it tells you there's no events pending. So then you think, go
deeper, use `XPending()` instead. Same thing, GTK hasn't actually issued
the command to Xlib yet. So then you think, if the widget is realized,
just call a blocking `gtk_main_iteration`. One call does nothing, two
calls results in a deadlock on the second one ... do it before program
startup, and the main window will never appear. Great.

Oh, and it's not just the viewport. It's also the widget container area
of the windows, as well as the window itself, as well as the fullscreen
mode toggle effect. They all do this.

For the latter three, I couldn't find anything that worked, so I just
added 20ms loops of constantly calling `gtk_main_iteration_do(false)`
after each one of those things. The downside here is toggling the status
bar takes 40ms, so you'll see it and it'll feel a tiny bit sluggish.

But I can't have a 20ms wait on each widget resize, that would be
catastrophic to performance on windows with lots of widgets.

I tried hooking configure-event and size-allocate, but they were very
unreliable. So instead I ended up with a loop that waits up to a maximm
of 20ms that inspects the `widget->allocation.(width,height)` values
directly and waits for them to be what we asked for with
`set_size_request`.

There was some extreme ugliness in GTK with calling
`gtk_main_iteration_do` recursively (`hiro::Widget::setGeometry` is
called recursively), so I had to lock it to only happen on the top level
widgets (the child ones should get resized while waiting on the
top-level ones, so it should be fine in practice), and also only run it
on realized widgets.

Even still, I'm getting ~3 timeouts when opening the settings dialog in
higan, but no other windows. But, this is the best I can do for now.

And the reason for all of this pain? Yeah, updated the video code.

So the Emulator::Interface now has this:

    struct VideoSize { uint width, height; };  //or requiem for a tuple
    auto videoSize() -> VideoSize;
    auto videoSize(uint width, uint height, bool arc) -> VideoSize;

The first function, for now, is just returning the literal surface size.
I may remove this ... one thing I want to allow for is cores that send
different texture sizes based on interlace/hires/overscan/etc settings.

The second function is more interesting. Instead of having the UI trying
to figure out sizing, I figure the emulation cores can do a better job
and we can customize it per-core now. So it gets the window's width and
height, and whether the user asked for aspect correction, and then
computes the best width/height ratio possible. For now they're all just
doing multiples of a 1x scale to the UI 2x,3x,4x modes.

We still need a third function, which will probably be what I repurpose
videoSize() for: to return the 'effective' size for pixel shaders, to
then feed into ruby, to then feed into quark, to then feed into our
shaders. Since shaders use normalized coordinates for pixel fetching,
this should work out just fine. The real texture size will be exposed to
quark shaders as well, of course.

Now for the main window ... it's just hard-coded to be 640x480, 960x720,
1280x960 for now. It works nicely for some cores on some modes, not so
much for others. Work in progress I guess.

I also took the opportunity to draw the about dialog box logo on the
main window. Got a bit fancy and used the old spherical gradient and
impose functionality of nall/image on it. Very minor highlight, nothing
garish. Just something nicer than a solid black window.

If you guys want to mess around with sizes, placements, and gradient
styles/colors/shapes ... feel free. If you come up with something nicer,
do share.

That's what led to all the GTK hell ... the logo wasn't drawing right as
you resized the window. But now it is, though I am not at all happy with
the hacking I had to do.

I also had to improve the video update code as a result of this:

  - when you unload a game, it blacks out the screen
      - if you are not quitting the emulator, it'll draw the logo; if
        you are, it won't
  - when you load a game, it black out the logo

These options prevent any unsightliness from resizing the viewport with
image data on it already

I need to redraw the logo when toggling fullscreen with no game loaded
as well for Windows, it seems.

Tim Allen e39987a3e3 Update to v101 release.
byuu says (in the public announcement):

Not a large changelog this time, sorry. This release is mostly to fix
the SA-1 issue, and to get some real-world testing of the new scheduler
model. Most of the work in the past month has gone into writing a 68000
CPU core; yet it's still only about half-way finished.

Changelog (since the previous release):

  - fixed SNES SA-1 IRQ regression (fixes Super Mario RPG level-up
    screen)
  - new scheduler for all emulator cores (precision of 2^-127)
  - icarus database adds nine new SNES games
  - added Input/Frequency to settings file (allows simulation of
    latency)

byuu says (in the WIP forum):

Changelog:

  - in 32-bit mode, Thread uses uint64\_t with 2^-63 time units (10^-7
    precision in the worst case)
      - nearly ten times the precision of an attosecond
  - in 64-bit mode, Thread uses uint128\_t with 2^-127 time units
    (10^-26 precision in the worst case)
      - far more accurate than yoctoseconds; almost closing in on planck
        time

Note: a quartz crystal is accurate to 10^-4 or 10^-5. A cesium fountain
atomic clock is accurate to 10^-15. So ... yeah. 2^-63 was perfectly
fine; but there was no speed penalty whatsoever for using uint128\_t in
64-bit mode, so why not?

Tim Allen f5e5bf1772 Update to v100r16 release.
byuu says:

(Windows users may need to include <sys/time.h> at the top of
nall/chrono.hpp, not sure.)

Unchangelog:
- forgot to add the Scheduler clock=0 fix because I have the memory of
  a goldfish

Changelog:
- new icarus database with nine additional games
- hiro(GTK,Qt) won't constantly write its settings.bml file to disk
  anymore
- added latency simulator for fun (settings.bml => Input/Latency in
  milliseconds)

So the last one ... I wanted to test out nall::chrono, and I was also
thinking that by polling every emulated frame, it's pretty wasteful when
you are using Fast Forward and hitting 200+fps. As I've said before,
calls to ruby::input::poll are not cheap.

So to get around this, I added a limiter so that if you called the
hardware poll function within N milliseconds, it'll return without
doing any actual work. And indeed, that increases my framerate of Zelda
3 uncapped from 133fps to 142fps. Yay. But it's not a "real" speedup,
as it only helps you when you exceed 100% speed (theoretically, you'd
need to crack 300% speed since the game itself will poll at 16ms at 100%
speed, but yet it sped up Zelda 3, so who am I to complain?)

I threw the latency value into the settings file. It should be 16,
but I set it to 5 since that was the lowest before it started negatively
impacting uncapped speeds. You're wasting your time and CPU cycles setting
it lower than 5, but if people like placebo effects it might work. Maybe
I should let it be a signed integer so people can set it to -16 and think
it's actually faster :P (I'm only joking. I took out the 96000hz audio
placebo effect as well. Not really into psychological tricks anymore.)

But yeah seriously, I didn't do this to start this discussion again for
the billionth time. Please don't go there. And please don't tell me this
WIP has higher/lower latency than before. I don't want to hear it.

The only reason I bring it up is for the fun part that is worth
discussing: put up or shut up time on how sensitive you are to
latency! You can set the value above 5 to see how games feel.

I personally can't really tell a difference until about 50. And I can't
be 100% confident it's worse until about 75. But ... when I set it to
150, games become "extra difficult" ... the higher it goes, the worse
it gets :D

For this WIP, I've left no upper limit cap. I'll probably set a cap of
something like 500ms or 1000ms for the official release. Need to balance
user error/trolling with enjoyability. I'll think about it.

[...]

Now, what I worry about is stupid people seeing it and thinking it's an
"added latency" setting, as if anyone would intentionally make things
worse by default. This is a limiter. So if 5ms have passed since the
game last polled, and that will be the case 99.9% of the time in games,
the next poll will happen just in time, immediately when the game polls
the inputs. Thus, a value below 1/<framerate>ms is not only pointless,
if you go too low it will ruin your fast forward max speeds.

I did say I didn't want to resort to placebo tricks, but I also don't
want to spark up public discussion on this again either. So it might
be best to default Input/Latency to 0ms, and internally have a max(5,
latency) wrapper around the value.

Tim Allen 07995c05a5 Update to v100 release.
byuu says:

higan has finally reached v100!

I feel it's important to stress right away that this is not "version
1.00", nor is it a major milestone release. Rather than arbitrary version
numbers, all of my software simply bumps version numbers by one for each
official release. As such, higan v100 is simply higan's 100th release.

That said, the primary focus of this release has been code
clean-ups. These are always somewhat dangerous in that regressions are
possible. We've tested through sixteen WIP revisions, one of which was
open to the public, to try and minimize any regressions. But all the same,
please report any regressions if you discover any.

Changelog (since v099):
FC: render during pixels 1-256 instead of 0-255 [hex_usr]
FC: rewrote controller emulation code
SFC: 8% speedup over the previous release thanks to PPU optimizations
SFC: fixed nasty DB address wrapping regression from v099
SFC: USART developer controller removed; superseded by 21fx
SFC: Super Multitap option removed from controller port 1; ports
    renamed 2-5
SFC: hidden option to experiment with 128KB VRAM (strictly for novelty)
higan: audio volume no longer divided by number of audio streams
higan: updated controller polling code to fix possible future mapping
    issues
higan: replaced nall/stream with nall/vfs for file-loading subsystem
tomoko: can now load multi-slotted games via command-line
tomoko: synchronize video removed from UI; still available in the
    settings file
tomoko, icarus: can navigate to root drive selection on Windows
all: major code cleanups and refactoring (~1MB diff against v099)

Note 1: the audio volume change means that SGB and MSU1 games won't
lose half the volume on the SNES sounds anymore. However, if one goes
overboard and drives the sound all the way to max volume with the MSU1,
clamping may occur. The obvious solution is not to drive volume that high
(it will vastly overpower the SNES audio, which usually never exceeds
25% volume.) Another option is to lower the volume in the audio settings
panel to 50%. In general, neither is likely to ever be necessary.

Note 2: the synchronize video option was hidden from the UI because it
is no longer useful. With the advent of compositors, the loss of the
complicated timing settings panel, support for the WonderSwan and its
75hz display, the need to emulate variable refresh rate behaviors in the
Game Boy, the unfortunate latency spike and audio distortion caused by
long Vsync pauses, and the arrival of adaptive sync technology ... it
no longer makes sense to present this option. However, as stated, you
can edit settings.bml to enable this option anyway if you insist and
understand the aforementioned risks.

Changelog (since v099r16 open beta):

- fixed MSU1 audio sign extension
- fixed compilation with SGB support disabled
- icarus can now navigate to root directory
- fixed compilation issues with OS X port
- (hopefully) fixed label height issue with hiro that affected icarus
  import dialog
- (mostly) fixed BS Memory, Sufami Turbo slot loading

Errata:

- forgot to remove the " - Slot A", " - Slot B" suffixes for Sufami
  Turbo slot loading
  - this means you have to navigate up one folder and then into Sufami
    Turbo/ to load games for this system
- moving WonderSwan orientation controls to the device slot is causing
  some nastiness
  - can now select orientation from the main menu, but it doesn't rotate
    the display
2016-07-08 22:04:59 +10:00
Tim Allen 13ad9644a2 Update to v099r16 release (public beta).
byuu says:

Changelog:
- hiro: BrowserDialog can navigate up to drive selection on Windows
- nall: (file,path,dir,base,prefix,suffix)name =>
  Location::(file,path,dir,base,prefix,suffix)
- higan/tomoko: rename audio filter label from "Sinc" to "IIR - Biquad"
- higan/tomoko: allow loading files via icarus on the command-line
  once again
- higan/tomoko: (begrudging) quick hack to fix presentation window focus
  on startup
- higan/audio: don't divide output audio volume by number of streams
- processor/r65816: fix a regression in (read,write)DB; fixes Taz-Mania
- fixed compilation regressions on Windows and Linux

I'm happy with where we are at with code cleanups and stability, so I'd
like to release v100. But even though I'm not assigning any special
significance to this version, we should probably test it more thoroughly
first.
2016-07-04 21:53:24 +10:00
Tim Allen 8d5cc0c35e Update to v099r15 release.
byuu says:

Changelog:
- nall::lstring -> nall::string_vector
- added IntegerBitField<type, lo, hi> -- hopefully it works correctly...
- Multitap 1-4 -> Super Multitap 2-5
- fixed SFC PPU CGRAM read regression
- huge amounts of SFC PPU IO register cleanups -- .bits really is lovely
- re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU
  - but they're now optimized to the realities of the PPU (16-bit data
    sizes / no address parameter / where appropriate)
  - basically used to get the active-display overrides in a unified place;
    but also reduces duplicate code in (read,write)IO
2016-07-04 21:48:17 +10:00
Tim Allen 82293c95ae Update to v099r14 release.
byuu says:

Changelog:
- (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel
  like they were contributing enough to be worth it]
- cleaned up nall::integer,natural,real functionality
  - toInteger, toNatural, toReal for parsing strings to numbers
  - fromInteger, fromNatural, fromReal for creating strings from numbers
  - (string,Markup::Node,SQL-based-classes)::(integer,natural,real)
    left unchanged
  - template<typename T> numeral(T value, long padding, char padchar)
    -> string for print() formatting
    - deduces integer,natural,real based on T ... cast the value if you
      want to override
    - there still exists binary,octal,hex,pointer for explicit print()
      formatting
- lstring -> string_vector [but using lstring = string_vector; is
  declared]
  - would be nice to remove the using lstring eventually ... but that'd
    probably require 10,000 lines of changes >_>
- format -> string_format [no using here; format was too ambiguous]
- using integer = Integer<sizeof(int)*8>; and using natural =
  Natural<sizeof(uint)*8>; declared
  - for consistency with boolean. These three are meant for creating
    zero-initialized values implicitly (various uses)
- R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees
  up struct IO {} io; naming]
- SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {}
  (status,registers); now
  - still some CPU::Status status values ... they didn't really fit into
    IO functionality ... will have to think about this more
- SFC CPU, PPU, SMP now use step() exclusively instead of addClocks()
  calling into step()
- SFC CPU joypad1_bits, joypad2_bits were unused; killed them
- SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it
- SFC PPU OAM moved into PPU::Object; since nothing else uses it
  - the raw uint8[544] array is gone. OAM::read() constructs values from
    the OAM::Object[512] table now
  - this avoids having to determine how we want to sub-divide the two
    OAM memory sections
  - this also eliminates the OAM::synchronize() functionality
- probably more I'm forgetting

The FPS fluctuations are driving me insane. This WIP went from 128fps to
137fps. Settled on 133.5fps for the final build. But nothing I changed
should have affected performance at all. This level of fluctuation makes
it damn near impossible to know whether I'm speeding things up or slowing
things down with changes.

Tim Allen b08449215a Update to v098r18 release.
byuu says:

Changelog:
- hiro: fixed the BrowserDialog column resizing when navigating to new
  folders (prevents clipping of filenames)
  - note: this is kind of a quick-fix; but I have a good idea how to do
    the proper fix now
- nall: added BitField<T, Lo, Hi> class
  - note: not yet working on the SFC CPU class; need to go at it with
    a debugger to find out what's happening
- GB: emulated DMG/SGB STAT IRQ bug; fixes Zerd no Densetsu and Road Rash
  (won't fix anything else; don't get hopes up)
2016-06-07 21:55:03 +10:00
Tim Allen ae5d380d06 Update to v098r11 release.
byuu says:

Changelog:
- fixed nall/path.hpp compilation issue
- fixed ruby/audio/xaudio header declaration compilation issue (again)
- cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the
  file was whitespace overkill)
- added null terminator entry to nall/windows/utf8.hpp argc[] array
- nall/windows/guid.hpp uses the Windows API for generating the GUID
  - this should stop all the bug reports where two nall users were
    generating GUIDs at the exact same second
- fixed hiro/cocoa compilation issue with uint# types
- fixed major higan/sfc Super Game Boy audio latency issue
- fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions
- major cleanups to higan/processor/r65816 core
  - merged emulation/native-mode opcodes
  - use camel-case naming on memory.hpp functions
  - simplify address masking code for memory.hpp functions
  - simplify a few opcodes themselves (avoid redundant copies, etc)
  - rename regs.* to r.* to match modern convention of other CPU cores
- removed device.order<> concept from Emulator::Interface
  - cores will now do the translation to make the job of the UI easier
- fixed plurality naming of arrays in Emulator::Interface
  - example: emulator.ports[p].devices[d].inputs[i]
  - example: vector<Medium> media
- probably more surprises

Major show-stoppers to the next official release:
- we need to work on GB core improvements: LY=153/0 case, multiple STAT
  IRQs case, GBC audio output regs, etc.
- we need to re-add software cursors for light guns (Super Scope,
  Justifier)
- after the above, we need to fix the turbo button for the Super Scope

I really have no idea how I want to implement the light guns. Ideally,
we'd want it in higan/video, so we can support the NES Zapper with the
same code. But this isn't going to be easy, because only the SNES knows
when its output is interlaced, and its resolutions can vary as
{256,512}x{224,240,448,480} which requires pixel doubling that was
hard-coded to the SNES-specific behavior, but isn't appropriate to be
exposed in higan/video.

Tim Allen 3ebc77c148 Update to v098r10 release.
byuu says:

Changelog:
- synchronized tomoko, loki, icarus with extensive changes to nall
  (118KiB diff)
2016-05-16 19:51:12 +10:00
Tim Allen 6ae0abe3d3 Update to v098r09 release.
byuu says:

Changelog:
- fixed major nall/vector/prepend bug
- renamed hiro/ListView to hiro/TableView
- added new hiro/ListView control which is a simplified abstraction of
  hiro/TableView
- updated higan's cheat database window and icarus' scan dialog to use
  the new ListView control
- compilation works once again on all platforms (Windows, Cocoa, GTK,
  Qt)
- the loki skeleton compiles once again (removed nall/DSP references;
  updated port/device ID names)

Small catch: need to capture layout resize events internally in Windows
to call resizeColumns. For now, just resize the icarus window to get it
to use the full window width for list view items.
2016-05-04 20:07:13 +10:00
Tim Allen 0955295475 Update to v098r08 release.
byuu says:

Changelog:
- nall/vector rewritten from scratch
- higan/audio uses nall/vector instead of raw pointers
- higan/sfc/coprocessor/sdd1 updated with new research information
- ruby/video/glx and ruby/video/glx2: fuck salt glXSwapIntervalEXT!

The big change here is definitely nall/vector. The Windows, OS X and Qt
ports won't compile until you change some first/last strings to
left/right, but GTK will compile.

I'd be really grateful if anyone could stress-test nall/vector. Pretty
much everything I do relies on this class. If we introduce a bug, the
worst case scenario is my entire SFC game dump database gets corrupted,
or the byuu.org server gets compromised. So it's really critical that we
test the hell out of this right now.

The S-DD1 changes mean you need to update your installation of icarus
again. Also, even though the Lunar FMV never really worked on the
accuracy core anyway (it didn't initialize the PPU properly), it really
won't work now that we emulate the hard-limit of 16MiB for S-DD1 games.
2016-05-02 19:57:04 +10:00
Tim Allen 7dc62e3a69 Update to v097r19 release.
byuu says:

Changelog:
- fixed nall/windows/guard.hpp
- fixed hiro/(windows,gtk)/header.hpp
- fixed Famicom PPU OAM reads (mask the correct bits when writing)
  [hex_usr]
- removed the need for (system := system) lines from higan/GNUmakefile
- added "All" option to filetype dropdown for ROM loading
  - allows loading GBC games in SGB mode (and technically non-GB(C)
    games, which will obviously fail to do anything)
- loki can load and play game folders now (command-line only) (extremely
  unimpressive; don't waste your time :P)
  - the input is extremely hacked in as a quick placeholder; not sure
    how I'm going to do mapping yet for it
2016-03-13 11:22:14 +11:00
Tim Allen fc7d5991ce Update to v097r18 release.
byuu says:

Changelog:
- fixed SNES sprite priority regression from r17
- added nall/windows/guard.hpp to guard against global namespace
  pollution (similar to nall/xorg/guard.hpp)
- almost fixed Windows compilation (still accuracy profile only, sorry)
- finished porting all of gba/ppu's registers over to the new .bit,.bits
  format ... all GBA registers.cpp files gone now
- the "processors :=" line in the target-$(ui)/GNUmakefile is no longer
  required
  - processors += added to each emulator core
  - duplicates are removed using the new nall/GNUmakefile's $(unique)
    function
- SFC core can be compiled without the GB core now
  - "-DSFC_SUPERGAMEBOY" is required to build in SGB support now (it's
    set in target-tomoko/GNUmakefile)
- started once again on loki (higan/target-loki/) [as before, loki is
  Linux/BSD only on account of needing hiro::Console]

loki shouldn't be too horrendous ... I hope. I just have the base
skeleton ready for now. But the code from v094r08 should be mostly
copyable over to it. It's just that it's about 50KiB of incredibly
tricky code that has to be just perfect, so it's not going to be quick.
But at least with the skeleton, it'll be a lot easier to pick away at it
as I want.

Windows compilation fix: move hiro/windows/header.hpp line 18 (header
guard) to line 16 instead.

Tim Allen 0d0af39b44 Update to v097r14 release.
byuu says:

This is a few days old, but oh well.

This WIP changes nall,hiro,ruby,icarus back to (u)int(8,16,32,64)_t.

I'm slowly pushing for (u)int(8,16,32,64) to use my custom
Integer<Size>/Natural<Size> classes instead. But it's going to be one
hell of a struggle to get that into higan.
2016-02-16 20:11:58 +11:00
Tim Allen 1fdd0582fc Update to v097 release.
byuu says:

This release features improvements to all emulation cores, but most
substantially for the Game Boy core. All of blargg's test ROMs that pass
in gambatte now either pass in higan, or are off by 1-2 clocks (the
actual behaviors are fully emulated.) I consider the Game Boy core to
now be fairly accurate, but there's still more improvements to be had.

Also, what's sure to be a major feature for some: higan now has full
support for loading and playing ordinary ROM files, whether they have
copier headers, weird extensions, or are inside compressed archives. You
can load these games from the command-line, from the main Library menu
(via Load ROM Image), or via drag-and-drop on the main higan window. Of
course, fans of game folders and the library need not worry: that's
still there as well.

Also new, you can drop the (uncompressed) Game Boy Advance BIOS onto the
higan main window to install it into the correct location with the
correct file name.

Lastly, this release technically restores Mac OS X support. However,
it's still not very stable, so I have decided against releasing binaries
at this time. I'd rather not rush this and leave a bad first impression
for OS X users.

Changelog (since v096):
- higan: project source code hierarchy restructured; icarus directly
  integrated
- higan: added software emulation of color-bleed, LCD-refresh,
  scanlines, interlacing
- icarus: you can now load and import ROM files/archives from the main
  higan menu
- NES: fixed manifest parsing for board mirroring and VRC pinouts
- SNES: fixed manifest for Star Ocean
- SNES: fixed manifest for Rockman X2,X3
- GB: enabling LCD restarts frame
- GB: emulated extra OAM STAT IRQ quirk required for GBVideoPlayer
  (Shonumi)
- GB: VBK, BGPI, OBPI are readable
- GB: OAM DMA happens inside PPU core instead of CPU core
- GB: fixed APU length and sweep operations
- GB: emulated wave RAM quirks when accessing while channel is enabled
- GB: improved timings of several CPU opcodes (gekkio)
- GB: improved timings of OAM DMA refresh (gekkio)
- GB: CPU uses open collector logic; return 0xFF for unmapped memory
  (gekkio)
- GBA: fixed sequencer enable flags; fixes audio in Zelda - Minish Cap
  (Jonas Quinn)
- GBA: fixed disassembler masking error (Lioncash)
- hiro: Cocoa support added; higan can now be compiled on Mac OS X 10.7+
- nall: improved program path detection on Windows
- higan/Windows: moved configuration data from %appdata% to
  %localappdata%
- higan/Linux,BSD: moved configuration data from ~/.config/higan to
  ~/.local/higan

Tim Allen 72b6a8b32e Update to v096r04 release.
byuu says:

Changelog:
- fixed S-DD1 RAM writes (Star Ocean audio fixed)
- applied all of the DMG test ROM fixes discussed earlier; passes many
  more test ROMs now
- at least until the GBVideoPlayer is working: for debugging purposes,
  CPU/PPU single-step now instead of sync just-in-time (~30% slower)
- fixed OS X crash on NSTextView (hopefully, would be very odd if not)

Unfortunately passing these test ROMs caused my favorite GB/GBC game to
break all of its graphics =(
Shin Megami Tensei - Devichil - Kuro no Sho (Japan) is all garbled now.
I'm really quite bummed by this ... but I guess I'll go through and
revert r04's fixes one at a time until I find what's causing it.

On the plus side, Astro Rabby is playable now. Still acts weird when
pressing B/A on the first screen, but the start button will start the
game.

EDIT: got it. Shin Megami Tensei - Devichil requires FF4F (VBK) to be
readable. Before, it was always returning 0x00. With my return 0xFF
patch, that broke. But it should be returning the VBK value, which also
fixes it. Also need to handle FF68/FF6A reads. Was really hoping that'd
help GBVideoPlayer too, but nope. It doesn't read any of those three
registers.

Changelog:
- fixed icarus to save settings properly
- fixed higan's full screen toggle on OS X
- increased "Add Codes" button width to avoid text clipping
- implemented cocoa/canvas.cpp
- added 1s delay after mapping inputs before re-enabling the window
  (wasn't actually necessary, but already added it)
- fixed setEnabled(false) on Cocoa's ListView and TextEdit widgets
- updated nall::programpath() to use GetModuleFileName on Windows

Tim Allen 0b923489dd Update to 20160106 OS X Preview for Developers release.
byuu says:

New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.

Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
  supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off
2016-01-07 19:17:15 +11:00
Tim Allen 4d193d7d94 Update to v096r02 (OS X Preview for Developers) release.
byuu says:

Warning: this is not for the faint of heart. This is a very early,
unpolished, buggy release. But help testing/fixing bugs would be greatly
appreciated for anyone willing.

Requirements:
- Mac OS X 10.7+
- Xcode 7.2+

Installation Commands:

    cd higan
    gmake -j 4
    gmake install
    cd ../icarus
    gmake -j 4
    gmake install

(gmake install is absolutely required, sorry. You'll be missing key
files in key places if you don't run it, and nothing will work.)

(gmake uninstall also exists, or you can just delete the .app bundles
from your Applications folder, and the Dev folder on your desktop.)

If you want to use the GBA emulation, then you need to drop the GBA BIOS
into ~/Emulation/System/Game\ Boy\ Advance.sys\bios.rom

Usage:
You'll now find higan.app and icarus.app in your Applications folders.
First, run icarus.app, navigate to where you keep your game ROMs. Now
click the settings button at the bottom right, and check "Create
Manifests", and click OK. (You'll need to do this every time you run
icarus because there's some sort of bug on OSX saving the settings.) Now
click "Import", and let it bring in your games into ~/Emulation.

Note: "Create Manifests" is required. I don't yet have a pipe
implementation on OS X for higan to invoke icarus yet. If you don't
check this box, it won't create manifest.bml files, and your games won't
run at all.

Now you can run higan.app. The first thing you'll want to do is go to
higan->Preferences... and assign inputs for your gamepads. At the very
least, do it for the default controller for all the systems you want to
emulate.

Now this is very important ... close the application at this point so
that it writes your config file to disk. There's a serious crashing bug,
and if you trigger it, you'll lose your input bindings.

Now the really annoying part ... go to Library->{System} and pick the
game you want to play. Right now, there's a ~50% chance the application
will bomb. It seems the hiro::pListView object is getting destroyed, yet
somehow the internal Cocoa callbacks are being triggered anyway. I don't
know how this is possible, and my attempts to debug with lldb have been
a failure :(

If you're unlucky, the application will crash. Restart and try again. If
it crashes every single time, then you can try launching your game from
the command-line instead. Example:

    open /Applications/higan.app \
	--args ~/Emulation/Super\ Famicom/Zelda3.sfc/

Help wanted:
I could really, really, really use some help with that crashing on game
loading. There's a lot of rough edges, but they're all cosmetic. This
one thing is pretty much the only major show-stopping issue at the
moment, preventing a wider general audience pre-compiled binary preview.

Tim Allen 47d4bd4d81 Update to v096r01 release.
byuu says:

Changelog:

- restructured the project and removed a whole bunch of old/dead
  directives from higan/GNUmakefile
- huge amounts of work on hiro/cocoa (compiles but ~70% of the
  functionality is commented out)
- fixed a masking error in my ARM CPU disassembler [Lioncash]
- SFC: decided to change board cic=(411,413) back to board
  region=(ntsc,pal) ... the former was too obtuse

If you rename Boolean (it's a problem with an include from ruby, not
from hiro) and disable all the ruby drivers, you can compile an
OS X binary, but obviously it's not going to do anything.

It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.
2015-12-30 17:54:59 +11:00
Tim Allen 0253db8685 Update to higan and icarus v095r17 release.
byuu says:

higan supports Event mapping again.

Further, icarus can now detect Event ROMs and MSU1 games.

Event ROMs must be named "program.rom", "slot-(1,2,3).rom" MSU1 games
must contain "msu1.rom"; and tracks must be named "track-#.pcm"

When importing the CC'92, PF'94 ROMs, the program.rom and
slot-(1,2,3).rom files must be concatenated. The DSP firmware can
optionally be separate, but I'd recommend you go ahead and merge it all
to one file. Especially since that common "higan DSP pack" floating
around on the web left out the DSP1 ROMs (only has DSP1B) for god knows
what reason.

There is no support for loading "game.sfc+game.msu+game-*.pcm", because
I'm not going to support trying to pull in all of those files through
importing. Games will have to be distributed as game folders to use
MSU1. The MSU1 icarus support is simply so your game folders won't
require an unstable manifest.bml file to be played. So once they're in
there, they are good for life.

Note: the Event sizes in icarus' SFC heuristics are wrong for appended
firmware. Change from 0xXX8000 to 0xXX2000 and it works fine. Will be
fixed in r18.

Added Sintendo's flickering fixes. The window one's a big help for
regular controls, but the ListView double buffering does nothing for me
on Windows 7 :( Fairly sure I know why, but too lazy to try and fix that
now.

Also fixes the mMenu thing.

Tim Allen bd628de3cf Update to higan and icarus v095r15 release.
r13 and r14 weren't posted as individual releases, but their changelogs
were posted.

byuu says about r13:

    I'm not going to be posting WIPs for r13 and above for a while.

    The reason is that I'm working on the major manifest overhaul I've
    discussed previously on the icarus subforum.

    I'm recreating my boards database from scratch using the map files
    and the new map analyzer. The only games that will load are ones
    I've created board definitions for, and updated
    sfc/cartridge/markup.cpp to parse. Once I've finished all the
    boards, then I'll update the heuristics.

    Then finally, I'll sync the syntax changes over to the fc, gb, gba
    cores.

    Once that's done, I'll start posting WIPs again, along with a new
    build of icarus.

    But I'll still post changelogs as I work through things.

    Changelog (r13):
    - preservation: created new database-builder tool (merges
      region-specific databases with boards)
    - icarus: support new, external database format
      (~/.config/icarus/Database/(Super Famicom.bml, ...)
    - added 1A3B-(10,11,12); 1A3B-20

byuu says about r14:

    r14 work:

    I successfully created mappings for every board used in the US set.

    I also updated icarus' heuristics to use the new mappings, and
    created ones there for the boards that are only in the JP set.

    Then I patched icarus to support pulling games out of the database
    when it's used on a game folder to generate a manifest file.

    Then I updated a lot of code in higan/sfc to support the new mapping
    syntax. sfc/cartridge/markup.cpp is about half the size it used to
    be with the new mappings, and I was able to kill off both map/id and
    map/select entirely.

    Then I updated all four emulated systems (and both subsystems) to
    use "board" as the root node, and harmonized their syntax (made them
    all more consistent with each other.)

    Then I added a manifest viewer to the tools window+menu. It's kind
    of an advanced user feature, but oh well. No reason to coddle people
    when the feature is very useful for developers. The viewer will show
    all manifests in order when you load multi-cart games as well.

    Still not going to call any syntax 100% done right now, but
    thankfully with the new manifest-free folders, nobody will have to
    do anything to use the new format. Just download the new version and
    go.

    The Super Famicom Event stuff is currently broken (CC92/PF94
    boards). That's gonna be fun to support.

byuu says about r15:

    EDIT: small bug in icarus with heuristics. Edit
    core/super-famicom.cpp line 27:

	if(/*auto*/ markup = cartridge.markup) {

    Gotta remove that "auto" so that it returns valid markup.

    Resolved the final concerns I had with the new manifest format.

    Right now there are two things that are definitely broken: MCC (BS-X
    Town cart) and Event (CC '92 and PF'94).
    And there are a few things that are untested: SPC7110, EpsonRTC,
    SharpRTC, SDD1+RAM, SufamiTurbo, BS-X slotted carts.

Tim Allen f2a416aea9 Update to v095r11 release.
byuu says:

Changelog:
- SFC: "uint8 read(uint addr)" -> "uint8 read(uint addr, uint8 data)"
- hiro: mHorizontalLayout::setGeometry() return value
- hiro/GTK: ListView,TreeView::setFocused() does not grab focus of first
  item

Notes:
- nall/windows/utf8.hpp needs using uint = unsigned; at the top to
  compile
- sfc/balanced, sfc/performance won't compile yet

Seems Cx4 games broke a while back. Not from this WIP, either. I'll go
back and find out what's wrong now.
2015-12-14 20:41:06 +11:00
Tim Allen 41c478ac4a Update to v095r07 release.
byuu says:

Changelog:
- entire GBA core ported to auto function() -> return; syntax
- fixed GBA BLDY bug that was causing flickering in a few games
- replaced nall/config usage with nall/string/markup/node
  - this merges all configuration files to a unified settings.bml file
- added "Ignore Manifests" option to the advanced setting tab
  - this lets you keep a manifest.bml for an older version of higan; if
    you want to do regression testing

Be sure to remap your controller/hotkey inputs, and for SNES, choose
"Gamepad" from "Controller Port 1" in the system menu. Otherwise you
won't get any input. No need to blow away your old config files, unless
you want to.
2015-11-16 19:38:05 +11:00
Tim Allen 40f4b91000 Update to v095r06 release.
byuu says:

Changelog:
- fixed I/O register reads; perfect score on endrift's I/O tests now
- fixed mouse capture clipping on Windows [Cydrak]
- several hours of code maintenance work done on the SFC core

All higan/sfc files should now use the auto fn() -> ret; syntax. Haven't
converted all unsigned->uint yet. Also, probably won't do sfc/alt as
that's mostly just speed hack stuff.

Errata:
- forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor,
  which makes Super Scope / Justifier crash. Will be fixed in the next
  WIP.
2015-11-14 11:52:51 +11:00
Tim Allen 0fe55e3f5b Update to v095r03 release and icarus 20151107.
byuu says:

Note: you will need the new icarus (and please use the "no manifest"
system) to run GBA games with this WIP.

Changelog:
- fixed caching of r(d) to pass armwrestler tests [Jonas Quinn]
- DMA to/from GBA BIOS should fail [Cydrak]
- fixed sign-extend and rotate on ldrs instructions [Cydrak]
- fixed 8-bit SRAM reading/writing [byuu]
- refactored GBA/cartridge
  - cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash
  - things won't crash horribly if you specify a RAM size larger than
    the largest legal size in the manifest
  - specialized MROM / SRAM classes replace all the shared read/write
    functions that didn't work right anyway
- there's a new ruby/video.glx2 driver, which is not enabled by default
  - use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet
  - I'm not going to support OpenGL2 on Windows/OS X, because these OSes
    don't ship ancient video card drivers
- probably more. What am I, clairvoyant? :P

For endrift's tests, this gets us to 1348/1552 memory and 1016/1260
timing. Overall, this puts us back in second place. Only no$ is ahead
on memory, but bgba is even more ahead on timing.

Tim Allen 8476a12deb Update to v095r01 release (open beta).
byuu says:

Changelog:
- added MSU1 resume support
- updated sfc/dsp, sfc/controller to match my coding style

  mode
2015-10-10 13:16:12 +11:00
Tim Allen bc5ad4a1cd Update to icarus_20151002.
byuu says:

- fixes checkboxes (-again- again [*again*])
- won't check folders with select all / unselect all
- won't crash anymore if the SNES ROM image is too small (Saturday Night
  Slam Masters was crashing it before due to DB size error)
- corrected heuristics for Sufami Turbo base cart (mirrors the
  absurdities of the real cart precisely, since it's one of a kind)
- corrected a few DB issues (BS-X name + PSRAM (again [*again*]), SNSM,
  LAH) (_again_)
  - these are temporary. Monkey patched in the generated .hpp source
    rather than the actual DB
  - not going to fix the SFT sizes because I want to verify what
    happened there first
2015-10-03 16:25:39 +10:00
Tim Allen 483fc81356 Update to v094r44 release.
byuu says:

Changelog:
- return open bus instead of mirroring addresses on the bus (fixes
  Mario&Luigi, Minish Cap, etc) [Jonas Quinn]
- add boolean flag to load requests for slotted game carts (fixes slot
  load prompts)
- rename BS-X Town cart from psram to ram
- icarus: add support for game database

Note: I didn't rename "bsx" to "mcc" in the database for icarus before
uploading that. But I just fixed it locally, so it'll be in the next
WIP. For now, make it create the manifest for you and then rename it
yourself. I did fix the PSRAM size to 256kbit.
2015-10-01 20:00:28 +10:00
Tim Allen 0c87bdabed Update to v094r43 release.
byuu says:

Updated to compile with all of the new hiro changes. My next step is to
write up hiro API documentation, and move the API from alpha (constantly
changing) to beta (rarely changing), in preparation for the first stable
release (backward-compatible changes only.)

Added "--fullscreen" command-line option. I like this over
a configuration file option. Lets you use the emulator in both modes
without having to modify the config file each time.

Also enhanced the command-line game loading. You can now use any of
these methods:

    higan /path/to/game-folder.sfc
    higan /path/to/game-folder.sfc/
    higan /path/to/game-folder.sfc/program.rom

The idea is to support launchers that insist on loading files only.

Technically, the file can be any name (manifest.bml also works); the
only criteria is that the file actually exists and is a file, and not
a directory. This is a requirement to support the first version (a
directory lacking the trailing / identifier), because I don't want my
nall::string class to query the file system to determine if the string
is an actual existing file or directory for its pathname() / dirname()
functions.

Anyway, every game folder I've made so far has program.rom, and that's
very unlikely to change, so this should be fine.

Now, of course, if you drop a regular "game.sfc" file on the emulator,
it won't even try to load it, unless it's in a folder that ends in .fc,
.sfc, etc. In which case, it'll bail out immediately by being unable to
produce a manifest for what is obviously not really a game folder.

2015-08-24 19:42:11 +10:00
Tim Allen 213879771e Update to v094r41 release (open beta).
byuu says:

Changelog (since the last open beta):
- icarus is now included. icarus is used to import game files/archives
  into game paks (folders)
- SNES: mid-scanline BGMODE changes now emulated correctly (used only by
  atx2.smc Anthrox Demo)
- GBA: fixed a CPU bug that was causing dozens of games to have
  distorted audio
- GBA: fixed default FlashROM ID; should allow much higher compatibility
- GBA: now using Cydrak's new, much improved, GBA color emulation filter
  (still a work-in-progress)
- re-added command-line loading support for game paks (not for game
  files/archives, sorry!)
- Qt port now compiles and runs again (may be a little buggy;
  Windows/GTK+ ports preferred)
- SNES performance profile now compiles and runs again
- much more
2015-08-21 20:57:03 +10:00
Tim Allen 4344b916b6 Update to v094r40 release.
byuu says:

Changelog:
- updated to newest hiro API
- SFC performance profile builds once again
- hiro: Qt port completed

Errata 1: the hiro/Qt target won't run tomoko just yet. Starts by
crashing inside InputSettings because hiro/Qt isn't forcefully selecting
the first item added to a ComboButton just yet. Even with a monkey patch
to get around that, the UI is incredibly unstable. Lots of geometry
calculation bugs, and a crash when you try and access certain folders in
the browser dialog. Lots of work left to be done there, sadly.

Errata 2: the hiro/Windows port has black backgrounds on all ListView
items. It's because I need to test for unassigned colors and grab the
default Windows brush colors in those cases.

Note: alternating row colors on multi-column ListView widgets is gone
now. Not a bug. May add it back later, but I'm not sure. It doesn't
interact nicely with per-cell background colors.

Things left to do:

First, I have to fix the Windows and Qt target bugs.

Next, I need to go through and revise the hiro API even more (nothing
too major.)

Next, I need to update icarus to use the new hiro API, and add support
for the SFC games database.

Next, I have to rewrite my TSV->BML cheat code tool.

Next, I need to post a final WIP of higan+icarus publicly and wait a few
days.

Next, I need to fix any bugs reported from the final WIP that I can.

Finally, I should be able to release v095.
2015-08-18 20:18:00 +10:00
Tim Allen 0271d6a12b Update to v094r39 release.
byuu says:

Changelog:
- SNES mid-scanline BGMODE fixes finally merged (can run
  atx2.zip{mode7.smc}+mtest(2).sfc properly now)
- Makefile now discards all built-in rules and variables
- switch on bool warning disabled for GCC now as well (was already
  disabled for Clang)
- when loading a game, if any required files are missing, display
  a warning message box (manifest.bml, program.rom, bios.rom, etc)
- when loading a game (or a game slot), if manifest.bml is missing, it
  will invoke icarus to try and generate it
  - if that fails (icarus is missing or the folder is bad), you will get
    a warning telling you that the manifest can't be loaded

The warning prompt on missing files work for both games and the .sys
folders and their files. For some reason, failing to load the DMG/CGB
BIOS is causing a crash before I can display the modal dialog. I have no
idea why, and the stack frame backtrace is junk.

I also can't seem to abort the failed loading process. If I call
Program::unloadMedia(), I get a nasty segfault. Again with a really
nasty stack trace. So for now, it'll just end up sitting there emulating
an empty ROM (solid black screen.) In time, I'd like to fix that too.

Lastly, I need a better method than popen for Windows. popen is kind of
ugly and flashes a console window for a brief second even if the
application launched is linked with -mwindows. Not sure if there even is
one (I need to read the stdout result, so CreateProcess may not work
unless I do something nasty like "> %tmp%/temp") I'm also using the
regular popen instead of _wpopen, so for this WIP, it won't work if your
game folder has non-English letters in the path.

I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
  others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
  (consistency with SGB/ICD2)
- ... and more!
2015-08-04 19:01:59 +10:00
Tim Allen 092cac9073 Update to v094r37 release.
byuu says:

Changelog:
- synchronizes lots of nall changes
- changes displayed program title from tomoko to higan(*)
- browser dialog sort is case-insensitive
- .sys folders look at user-selected library path; no longer hard-coded

Tried to get rid of the file modes from the Windows browser dialog, but
it was being a bitch so I left it on for now.

- The storage locations and binary still use tomoko. I'm not really sure
  what to do here. The idea is there may be more than one "higan" UI in
  the future, but I don't want people to go around calling the entire
  program by the UI name. For official Windows releases, I can rename
  the binaries to "higan-{profile}.exe", and by putting the config files
  with the binary, they won't ever see the tomoko folder. Linux is of
  course trickier.

Note: Windows users will need to edit hiro/components.hpp and comment
out these lines:

 #define Hiro_Console
 #define Hiro_IconView
 #define Hiro_SourceView
 #define Hiro_TreeView

I forgot to do that, and too lazy to upload another WIP.

Tim Allen 7ff7f64482 Update to v094r34 release.
byuu says:

Fixes SuperFX fmult, lmult timings; rambr, bramr and clsr assignment
masking. Implements true GBA ROM prefetch (buggy, lower test score, but
runs Mario & Luigi without crashing on battles anymore.)
2015-06-28 18:44:56 +10:00
Tim Allen ea02f1e36a Update to v094r31 release.
byuu says:

This WIP scores 448/920 tests passed.

Gave a shot at ROM prefetch that failed miserably (ranged from 409 to
494 tests passed. Nowhere near where it would be if it were implemented
correctly.)

Three remaining issues:
- ROM prefetch
- DMA timing
- timers (I suspect it's a 3-clock delay in starting, not a 3-clock into
  the future affair)

Probably only going to be able to get the timers working without heroic
amounts of effort.

MUL timing is fixed to use idle cycles.
STMIA is fixed to set sequential at the right moments.
DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer.

In other news ...

I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those
Window_configure issues go away.

I realize I was leaking Display* handles in the X-video driver while
I was looking at it, so I fixed those.

I added DT_NOPREFIX so the Windows ListView will show & characters
correctly now.

Tim Allen 83f684c66c Update to v094r29 release.
byuu says:

Note: for Windows users, please go to nall/intrinsics.hpp line 60 and
correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before
compiling, otherwise things won't work at all.

This will be a really major WIP for the core SNES emulation, so please
test as thoroughly as possible.

I rewrote the 65816 CPU core's dispatcher from a jump table to a switch
table. This was so that I could pass class variables as parameters to
opcodes without crazy theatrics.

With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^=
stuff, and all of the template versions of opcodes.

I also removed some stupid pointless flag tests in xcn and pflag that
would always be true.

I sure hope that AWJ is happy with this; because this change was so that
my flag assignments and branch tests won't need to build regs.P into
a full 8-bit variable anymore.

It does of course incur a slight performance hit when you pass in
variables by-value to functions, but it should help with binary size
(and thus cache) by reducing a lot of extra functions. (I know I could
have used template parameters for some things even with a switch table,
but chose not to for the aforementioned reasons.)

Overall, it's about a ~1% speedup from the previous build. The CPU core
instructions were never a bottleneck, but I did want to fix the P flag
building stuff because that really was a dumb mistake v_v'

Tim Allen e0815b55b9 Update to v094r28 release.
byuu says:

This WIP substantially restructures the ruby API for the first time
since that project started.

It is my hope that with this restructuring, destruction of the ruby
objects should now be deterministic, which should fix the crashing on
closing the emulator on Linux. We'll see I guess ... either way, it
removed two layers of wrappers from ruby, so it's a pretty nice code
cleanup.

It won't compile on Windows due to a few issues I didn't see until
uploading the WIP, too lazy to upload another. But I fixed all the
compilation issues locally, so it'll work on Windows again with the next
WIP (unless I break something else.)

(Kind of annoying that Linux defines glActiveTexture but Windows
doesn't.)

Tim Allen 20cc6148cb Update to v094r27 release.
byuu says:

Added AWJ's fixes for alt/cpu (Tetris Attack framelines issue) and
alt/dsp (Thread::clock reset)

Added fix so that the taskbar entry appears when the application first
starts on Windows.

Fixed checkbox toggling inside of list views on Windows.

Updated nall/image to properly protect variables that should not be
written externally.

New Object syntax for hiro is in.

Fixed the backwards-typing on Windows with the state manager.
NOTE: the list view isn't redrawing when you change the description
text. It does so on the cheat editor because of the resizeColumns call;
but that shouldn't be necessary. I'll try and fix this for the next WIP.

Tim Allen a21ff570ee Update to v094r26 release (open beta).
byuu says:

Obviously, this is a fairly major WIP. It's the first public release in
17 months. The entire UI has been rewritten (for the 74th time), and is
now internally called tomoko. The official releases will be named higan
(both the binaries and title bar.)

Missing features from v094:

- ananke is missing (this means you will need v094 to create game
  folders to be loaded)
- key assignments are limited to one physical button = one mapping (no
  multi-mapping)
- shader support is missing
- audio/video profiling is missing
- DIP switch window is missing (used by NSS Actraiser with a special
  manifest; that's about it)
- alternate paths for game system folders and configuration BML files

There's some new stuff, but not much. This isn't going to be an exciting
WIP in terms of features. It's more about being a brand new release with
the brand new hiro port and its shared memory model. The goal is to get
these WIPs stable, get v095 out, and then finally start improving the
actual emulation again after that.

Tim Allen bb3c69a30d Update to v094r25 release.
byuu says:

Windows port should run mostly well now, although exiting fullscreen
breaks the application in a really bizarre way. (clicking on the window
makes it sink to background rather than come to the foreground o_O)

I also need to add the doModalChange => audio.clear() thing for the
accursed menu stuttering with DirectSound.

I also finished porting all of the ruby drivers over to the newer API
changes from nall.

Since I can't compile the Linux or OS X drivers, I have no idea if there
are any typos that will result in compilation errors. If so, please let
me know where they're at and I'll try and fix them. If they're simple,
please try and fix them on your end to test further if you can.

I'm hopeful the udev crash will be gone now that nall::string checks for
null char* values passed to its stringify function. Of course, it's
a problem it's getting a null value in the first place, so it may not
work at all.

If you can compile on Linux (or by some miracle, OS X), please test each
video/audio/input driver if you don't mind, to make sure there's no
"compiles okay but still typos exist" bugs.

Tim Allen f0c17ffc0d Update to v094r24 release.
byuu says:

Finally!! Compilation works once again on Windows.

However, it's pretty buggy. Modality isn't really working right, you can
still poke at other windows, but when you select ListView items, they
redraw as empty boxes (need to process WM_DRAWITEM before checking
modality.)

The program crashes when you close it (probably a ruby driver's term()
function, that's what it usually is.)

The Layout::setEnabled(false) call isn't working right, so you get that
annoying chiming sound and cursor movement when mapping keyboard keys to
game inputs.

The column sizing seems off a bit on first display for the Hotkeys tab.

And probably lots more.

Tim Allen 314aee8c5c Update to v094r23 release.
byuu says:

The library window is gone, and replaced with
hiro::BrowserWindow::openFolder(). This gives navigation capabilities to
game loading, and it also completes our slotted cart selection code. As
an added bonus, it's less code this way, too.

I also set the window size to consistent sizes between all emulated
systems, so that switching between SFC and GB don't cause the window
size to keep changing, and so that the scaling size is consistent (eg at
normal scale, GB @ 3x is closer to SNES @ 2x.) This means black borders
in GB/GBA mode, but it doesn't look that bad, and it's not like many
people ever use these modes anyway.

Finally, added the placeholder tabs for video, audio and timing. I don't
intend to add the timing calculator code to v095 (it might be better as
a separate tool), but I'll add the ability to set video/audio rates, at
least.

Glitch 1: despite selecting the first item in the BrowserDialog list, if
you press enter when the window appears, it doesn't activate the item
until you press an arrow key first.

Glitch 2: in Game Boy mode, if you set the 4x window size, it's not
honoring the full requested height because the viewport is smaller than
the window. 8+ years of trying to get GTK+ and Qt to simply set the god
damned window size I ask for, and I still can't get them to do it
reliably.

Remaining issues:
- finish configuration panels (video, audio, timing)
- fix ruby driver compilation on Windows
- add DIP switch selection window (NSS) [I may end up punting this one
  to v096]

Tim Allen 7bf4cff946 Update to v094r22 release.
byuu says:

I fixed the hiro layout enable bug, so when you go to assign joypad
input, the window disables itself so your input doesn't mess with the
controls.

I added "reset" to the hotkeys, in case you feel like clearing all of
them at once.

I added device selection support and the ability to disable audio
synchronization (run > 60fps) to the ruby/OSS driver. This is exposed in
tomoko's configuration file.

I added checks to stringify so that assigning null char* strings to
nall::string won't cause crashes anymore (technically the crash was in
strlen(), which doesn't check for null strings, but whatever ... I'll do
the check myself.)

I hooked up BrowserDialog::folderSelect() to loading slotted media for
now. Tested it by loading a Game Boy game successfully through the Super
Game Boy. Definitely want to write a custom window for this though, that
looks more like the library dialog.

Remaining issues:
- finish slotted cart loader (SGB, BSX, ST)
- add DIP switch selection window (NSS) [I may end up punting this one
  to v096]
- add more configuration panels (video, audio, timing)

Tim Allen 4e0223d590 Update to v094r20 release.
byuu says:

Main reason for this WIP was because of all the added lines to hiro for
selective component disabling. May as well get all the diff-noise apart
from code changes.

It also merges something I've been talking to Cydrak about ... making
nall::string::(integer,decimal) do built-in binary,octal,hex decoding
instead of just failing on those. This will have fun little side effects
all over the place, like being able to view a topic on my forum via
"forum.byuu.org/topic/0b10010110", heh.

There are two small changes to higan itself, though. First up, I fixed
the resampler ratio when loading non-SNES games. Tested and I can play
Game Boy games fine now. Second, I hooked up menu option hiding for
reset and controller selection. Right now, this works like higan v094,
but I'm thinking I might want to show the "Device -> Controller" even if
that's all that's there. It kind of jives nicer with the input settings
window to see the labels there, I think. And if we ever do add more
stuff, it'll be nice that people already always expect that menu there.

Remaining issues:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add timing configuration (video/audio sync)

Tim Allen 2eb50fd70b Update to v094r15 release.
byuu says:

Implemented the cheat database dialog, and most of the cheat editor
dialog. I still have to handle loading and saving the cheats.bml file
for each game. I wanted to finish it today, but I burned out. It's a ton
of really annoying work to support cheat codes. There's also some issue
with the width calculation for the "code(s)" column in hiro/GTK.

Short-term:
- add input port changing support
- add other input types (mouse-based, etc)
- finish cheat codes

Long-term:
- add slotted cart loader (SGB, BSX, ST)
- add DIP switch selection window (NSS)
- add overscan masking
- add timing configuration (video/audio sync)

Not planned:
- video color adjustments (will allow emulated color vs raw color; but
  no more sliders)
- pixel shaders
- ananke integration (will need to make a command-line version to get my
  games in)
- fancy audio adjustment controls (resampler, latency, volume)
- input focus settings
- localization support (not enough users)
- window geometry memory
- anything else not in higan v094

Tim Allen b4ba95242f Update to v094r13 release.
byuu says:

This version polishes up the input dialogue (reset, erase, disable
button when item not focused, split device ID from mapping name), adds
color emulation toggle, and add dummy menu items for remaining features
(to be filled in later.)

Also, it now compiles cleanly on Windows with GTK.

I didn't test with TDM-GCC-32, because for god knows what reason, the
32-bit version ships with headers from Windows 95 OSR2 only. So I built
with TDM-GCC-64 with arch=x86.

And uh, apparently, moving or resizing a window causes a Visual C++
runtime exception in the GTK+ DLLs. This doesn't happen with trance or
renshuu built with TDM-GCC-32. So, yeah, like I said, don't use -m32.

Tim Allen a1b2fb0124 Update to v094r12 release.
byuu says:

Changelog:
* added driver selection
* added video scale + aspect correction settings
* added A/V sync + audio mute settings
* added configuration file
* fixed compilation bugs under Windows and Linux
* fixed window sizing
* removed HSU1
* the system menu stays as "System", because "Game Boy Advance" was too
  long a string for the smallest scale size
* some more stuff

You guys probably won't be ecstatic about the video sizing options, but
it's basically your choice of 1x, 2x or 4x scale with optional aspect
correction. 3x was intentionally skipped because it looks horrible on
hires SNES games. The window is resized and recentered upon loading
games. The window doesn't resize otherwise. I never really liked the way
v094 always left you with black screen areas and left you with
off-centered window positions.

I might go ahead and add the pseudo-fullscreen toggle that will jump
into 4x mode (respecting your aspect setting.)

Short-term:
* add input port changing support
* add other input types (mouse-based, etc)
* add save states
* add cheat codes
* add timing configuration (video/audio sync)
* add hotkeys (single state)

We can probably do a new release once the short-term items are
completed.

Long-term:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add cheat code database
* add state manager
* add overscan masking

Not planned:
* video color adjustments (will allow emulated color vs raw color; but
  no more sliders)
* pixel shaders
* ananke integration (will need to make a command-line version to get my
  games in)
* fancy audio adjustment controls (resampler, latency, volume)
* input focus settings
* relocating game library (not hard, just don't feel like it)
* localization support (not enough users)
* window geometry memory
* anything else not in higan v094

Tim Allen 4a069761f9 Update to v094r11 release.
byuu says:

I've hooked up the input subsystem, and the input manager to assign
hotkeys.

So far I only have digital buttons working (keyboard only), and I'm not
planning on supporting input groups again (mapping multiple physical
buttons to one emulated button), but it's progress. As with the rest of
tomoko, the code's a lot more compact. The nice thing about redoing code
so many times is that each time you get a little bit better at it.

The input configuration is saved to ~/.config/tomoko/settings.bml (just
realized that I'm an idiot and need to rename it to input.bml)

Also hooked up game saves and cartridge unloading. Active controller
changing isn't hooked up yet, and I'll probably do it differently.

Oh, and I declared the ruby lines for other platforms.

Still need to add Cydrak's Windows compilation fixes. I am nothing if
not lazy :P

Tim Allen a512d14628 Update to v094r09 release.
byuu says:

This will easily be the biggest diff in the history of higan. And not in
a good way.

* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)

For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.

Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.

Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.

My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.
