Changelog:

  - gb/interface: fix Game Boy Color extension to be "gbc" and not "gb"
    [hex\_usr]
  - ms/interface: move Master System hardware controls below controller
    ports
  - sfc/ppu: improve latching behavior of BGnHOFS registers (not
    hardware verified) [AWJ]
  - tomoko/input: rework port/device mapping to support non-sequential
    ports and devices¹
      - todo: should add move() to inputDevice.mappings.append and
        inputPort.devices.append
      - note: there's a weird GCC 4.9 bug with brace initialization of
        InputEmulator; have to assign each field separately
  - tomoko: all windows sans the main presentation window can be
    dismissed with the escape key
  - icarus: the single file selection dialog ("Load ROM Image...") can
    be dismissed with the escape key
  - tomoko: do not pause emulation when FocusLoss/Pause is set during
    exclusive fullscreen mode
  - hiro/(windows,gtk,qt): implemented Window::setDismissable() function
    (missing from cocoa port, sorry)
  - nall/string: fixed printing of largest possible negative numbers (eg
    `INT_MIN`) [Sintendo]
      - 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:

  - ruby/video: cleaned up Direct3D9 driver and fixed catastrophic
    memory leak
  - ruby/video: added fullscreen exclusive mode support to the Direct3D9
    driver¹
  - ruby/video: minor cosmetic code cleanups to various drivers
  - tomoko: added support to always allow input when in fullscreen
    exclusive mode
  - tomoko: fixed window to not remove resizability flag when exiting
    fullscreen mode

¹: I am assuming that exclusive mode will try to capture the primary
monitor. I don't know what will happen in multi-monitor setups, however,
as I don't use such a setup here.

Also, I am using `D3DPRESENT_DISCARD` instead of `D3DPRESENT_FLIP`. I'm
not sure if this will prove better or worse, but I've heard it will
waste less memory, and having a BackBufferCount of 1 should still result
in page flipping anyway. The difference is supposedly just that you
can't rely on the back buffer being a valid copy of the previous frame
like you can with FLIP.

Lastly, if you want Vsync, you can edit the configuration file to enable
that, and then turn off audio sync.

Errata: "pause emulation when focus is lost" is not working with
exclusive mode. I need to add a check to never auto-pause when in
exclusive mode. Thanks to bun for catching that one.

Tim Allen ee982f098a Update to v103r11 release.
byuu says:

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.

Changelog:

  - gba/apu: fixed wave RAM nibble ordering (fixes audio in Castlevania,
    PocketNES)
  - emulator: restructured video information to just a single
    videoResolution() → VideoResolution function
      - returns "projected size" (between 160x144 and 320x240)
      - "internal buffer size" (up to 1280x480)
      - returns aspect correction multiplier that is to be applied to
        the width field
          - the value could be < 1.0 to handle systems with taller
            pixels; although higan doesn't emulate such a system
  - tomoko: all calculations for scaling and overscan masking are done
    by the GUI now
  - tomoko: aspect correction can be enabled in either windowed or
    fullscreen mode separately; moved to Video settings panel
  - tomoko: video scaling multipliers (against 320x240) can now me
    modified from the default (2,3,4) via the configuration file
      - use this as a really barebones way of supporting high DPI
        monitors; although the GUI elements won't scale nicely
      - if you set a value less than two, or greater than your
        resolution divided by 320x240, it's your own fault when things
        blow up. I'm not babysitting anyone with advanced config-file
        only options.
  - tomoko: added new adaptive windowed mode
      - when enabled, the window will shrink to eliminate any black
        borders when loading a game or changing video settings. The
        window will not reposition itself.
  - tomoko: added new adaptive fullscreen mode
      - when enabled, the integral scaling will be disabled for
        fullscreen mode, forcing the video to fill at least one
        direction of the video monitor completely.

I expect we will be bikeshedding for the next month on how to describe
the new video options, where they should appear in the GUI, changes
people want, etc ... but suffice to say, I'm happy with the
functionality, so I don't intend to make changes to -what- things do,
but I will entertain better ways to name things.

Tim Allen 191a71b291 Update to v103r08 release.

Changelog:

  - emulator: improved aspect correction accuracy by using
    floating-point calculations
  - emulator: added videoCrop() function, extended videoSize() to take
    cropping parameters¹
  - tomoko: the overscan masking function will now actually resize the
    viewport²
  - gba/cpu: fixed two-cycle delay on triggering DMAs; not running DMAs
    when the CPU is stopped
  - md/vdp: center video when overscan is disabled
  - pce/vce: resize video output from 1140x240 to 1120x240
  - tomoko: resize window scaling from 326x240 to 320x240
  - tomoko: changed save slot naming and status bar messages to indicate
    quick states vs managed states
  - tomoko: added increment/decrement quick state hotkeys
  - tomoko: save/load quick state hotkeys now save to slots 1-5 instead
    of always to 0
  - tomoko: increased overscan range from 0-16 to 0-24 (in case you want
    to mask the Master System to 240x192)

¹: the idea here was to decouple raw pixels from overscan masking.
Overscan was actually horrifically broken before. The Famicom outputs at
256x240, the Super Famicom at 512x480, and the Mega Drive at 1280x480.
Before, a horizontal overscan mask of 8 would not reduce the Super
Famicom or Mega Drive by nearly as much as the Famicom. WIth the new
videoCrop() function, the internals of pixel size distortions can be
handled by each individual core.

²: furthermore, by taking optional cropping information in
videoSize(), games can scale even larger into the viewport window. So
for example, before the Super Famicom could only scale to 1536x1440. But
by cropping the vertical resolution by 6 (228p effectively, still more
than NTSC can even show), I can now scale to 1792x1596. And wiht aspect
correction, that becomes a perfect 8:7 ratio of 2048x1596, giving me
perfectly crisp pixels without linear interpolation being required.

Errata: for some reason, when I save a new managed state with the SFC
core, the default description is being set to a string of what looks to
be hex numbers. I found the cause ... I'll fix this in the next release.

Note: I'd also like to hide the "find codes..." button if cheats.bml
isn't present, as well as update the SMP TEST register comment from
smp/timing.cpp

Tim Allen 561c6413a4 Update to v103 final release.
byuu says (in the public annoucement):

With this release, PC Engine, Master System, Game Gear, Mega Drive and
the newly added SuperGrafx support are now quite usable! They're far
from the best emulators for these systems, but with many bugfixes, full
sound emulation, and save state support ... many games are now fully
playable with decent accuracy. The Game Boy Advance emulation is also
now substantially improved with vastly improved sound quality and a new
dot-based PPU renderer. With that change, every single component in
higan is now cycle-based. Regrettably, these changes do carry a ~20%
performance penalty compared to GBA emulation in v102.

Changelog (since the previous release):

  - added SuperGrafx emulation
  - improved audio band-pass filtering for all emulated systems
  - screen rotation is now a hotkey; automatically rotates control
    bindings
  - screen rotation now supported on the Game Boy Advance as well (used
    by a small number of games)
  - massive improvements to Mega Drive emulation
  - massive code cleanups and rewrites to many CPU emulation cores
    (MOS6502, WDC65816, SPC700, etc)
  - Famicom, Master System, Mega Drive: added PAL emulation support
  - PC Engine, SuperGrafx, Master System, Game Gear, Mega Drive: added
    save state support
  - PC Engine, SuperGrafx: added PSG sound emulation
  - Master System, Game Gear: added PSG sound emulation
  - Mega Drive: added Z80 APU emulation [with help from Cydrak]
  - Mega Drive: added PSG sound emulation
  - Mega Drive: added YM2612 sound emulation [Cydrak]
  - Super Famicom: fixed Super Game Boy emulation
  - PC Engine: added save RAM support (using per-game PCE-CD backup RAM)
  - Game Boy Advance: substantial improvements to audio emulation
    quality
  - Game Boy Advance: convert scanline-based PPU renderer to a dot-based
    renderer
  - Game Boy Advance: properly initialize CPU state (fixes Classic NES
    Series games)
  - Game Boy Advance: MUL timing corrected [Jonas Quinn]
  - Mega Drive: emulate special mappers for Phantasy Star IV, Super
    Street Fighter II, etc.
  - Super Famicom: use darker luma for INIDISP=0 (large improvement to
    Final Fantasy III opening)
  - Super Famicom: fixed bugs in SMP OR1,AND1 instructions
  - cheat code database regrettably removed from official releases; will
    be made available separately
  - Famicom: PAL emulation improvements [hex\_usr]

Changelog:

  - higan: `Emulator::<Platform::load>()` now returns a struct containing
    both a path ID and a string option
  - higan: `Emulator::<Platform::load>()` now takes an optional final
    argument of string options
  - fc: added PAL emulation (finally, only took six years)
  - md: added PAL emulation
  - md: fixed address parameter to `VDP::Sprite::write()`; fixes missing
    sprites in Super Street Fighter II
  - md: emulated HIRQ counter; fixes many games
      - Super Street Fighter II - status bar
      - Altered Beast - status bar
      - Sonic the Hedgehog - Labyrinth Zone - water effect
      - etc.
  - ms: added PAL emulation
  - sfc: added the ability to override the default region auto-detection
  - sfc: removed "system.region" override setting from `Super Famicom.sys`
  - tomoko: added options list to game folder load dialog window
  - tomoko: added the ability to specify game folder load options on the
    command-line

So, basically ... Sega forced a change with the way region detection
works. You end up with games that can run on multiple regions, and the
content changes accordingly. Bare Knuckle in NTSC-J mode will become
Streets of Rage in NTSC-U mode. Some games can even run in both NTSC and
PAL mode.

In my view, there should be a separate ROM for each region a game was
released in, even if the ROM content were identical. But unfortunately
that's not how things were done by anyone else.

So to support this, the higan load dialog now has a drop-down at the
bottom-right, where you can choose the region to load games from. On the
SNES, it defaults to "Auto", which will pull the region setting from the
manifest, or fall back on NTSC. On the Mega Drive ... unfortunately, I
can't auto-detect the region from the ROM header. $1f0 is supposed to
contain a string like "JUE", but instead you get games like Maui Mallard
that put an "A" there, and other such nonsense. Sega was far more lax
than Nintendo with the ROM header validity. So for now at least, you
have to manually select your region every time you play a Mega Drive
game, thus you have "NTSC-J", "NTSC-U", and "PAL". The same goes for the
Master System for the same reason, but there's only "NTSC" and "PAL"
here. I'm not sure if games have a way to detect domestic vs
international consoles.

And for now ... the Famicom is the same as well, with no auto-detection.
I'd sincerely hope iNES has a header bit for the region, but I didn't
bother with updating icarus to support that yet.

The way to pass these parameters on the command-line is to prefix the
game path with "option:", so for example:

    higan "PAL:/path/to/Sonic the Hedgehog (USA, Europe).md"

If you don't provide a prefix, it uses the default (NTSC-J, NTSC, or
Auto.) Obviously, it's not possible to pass parameters with
drag-and-drop, so you will always get the default option in said case.

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.

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

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.

byuu says:

Changelog:
- higan/profile/ => higan/systems/ [temporary; unless we can't think of
  a better base folder name]
- god-damn-better-have fixed the input polling bug
- re-added command-line and drag-and-drop loading
  - command-line loading can now load multiple folders at once (SGB+GB
    game; Sufami Turbo+Slot A+Slot B; etc)
  - if you load just the base cart, it'll present you with a dialog to
    optionally load slotted cart(s)
- MSU1 now goes through nall/vfs instead of directly accessing the
  filesystem
- Famicom Cartridge, PPU cores updated to newer programming style
  - there's countless opportunity for BitField and .bits() in the PPU
    ... but I'm worried about breaking things

If anyone has a working MSU1 game and can test the changes out, that'd
be appreciated. I still don't have a test ROM on my dev box.

I wouldn't worry too much about extensively testing the Famicom PPU
changes just yet ... I'm still struggling with what to name the structs
inside the classes between all of my emulators, and the BitField/.bits()
changes will be much more important to test at a later date.

The only use case left for Emulator::Interface::path(uint id) is for
21fx emulation. This peripheral loads a DLL/SO via LoadLibrary/dlopen,
which do not have any official ways to open a file in RAM. I'm
very hesitant to use the portable trick of writing the memory to a
temporary file, loading it, and deleting the temporary file once done
... it's a real waste of disk activity. I might make something like
vfs::file::isVirtual->bool,path()->string to get around this. But even
once I do, the underlying LoadLibrary/dlopen call is still going to be
direct disk access.

- added support for 128KiB SNES PPU VRAM (for now, edit sfc/ppu/ppu.hpp
  VRAM::size=0x10000; to enable)

Overall, nall/vfs was a huge success!! We've substantially reduced
the amount of boilerplate code everywhere, while still allowing (even
easier than before) support for RAM-based game loading/saving. All of
nall/stream is dead and buried.

I am considering removing Emulator::Interface::Medium::id and/or
bootable flag. Or at least, doing something different with it. The
values for the non-bootable GB/BS/ST entries duplicate the ID that is
supposed to be unique. They are for GB/GBC and WS/WSC. Maybe I'll use
this as the hardware revision selection ID, and then gut non-bootable
options. There's really no reason for that to be there. I think at one
point I was using it to generate library tabs for non-bootable systems,
but we don't do that anymore anyway.

Emulator::Interface::load() may not need the required flag anymore ... it
doesn't really do anything right now anyway.

I have a few reasons for having the cores load the base cartridge. Most
importantly, it is going to enable a special mode for the WonderSwan /
WonderSwan Color in the future. If we ever get the IPLROMs dumped ... it's
possible to boot these systems with no games inserted to set user profile
information and such. There are also other systems that may accept being
booted without a cartridge. To reach this state, you would load a game and
then cancel the load dialog. Right now, this results in games not loading.

The second reason is this prevents nasty crashes when loading fails. So
if you're missing a required manifest, the emulator won't die a violent
death anymore. It's able to back out at any point.

The third reason is consistency: loading the base cartridge works the
same as the slot cartridges.

The fourth reason is Emulator::Interface::open(uint pathID)
values. Before, the GB, SB, GBC modes were IDs 1,2,3 respectively. This
complicated things because you had to pass the correct ID. But now
instead, Emulator::Interface::load() returns maybe<uint> that is nothing
when no game is selected, and a pathID for a valid game. And now open()
can take this ID to access this game's folder contents.

The downside, which is temporary, is that command-line loading is
currently broken. But I do intend on restoring it. In fact, I want to do
better than before and allow multi-cart booting from the command-line by
specifying the base cartridge and then slot cartridges. The idea should
be pretty simple: keep a queue of pending filenames that we fill from
the command-line and/or drag-and-drop operations on the main window,
and then empty out the queue or prompt for load dialogs from the UI
when booting a system. This also might be a bit more unorthodox compared
to the traditional emulator design of "loadGame(filename)", but ... oh
well. It's easy enough still.

The port/device changes are fun. We simplified things quite a bit. The
portmask stuff is gone entirely. While ports and devices keep IDs,
this is really just sugar-coating so UIs can use for(auto& port :
emulator->ports) and access port.id; rather than having to use for(auto
n : range(emulator->ports)) { auto& port = emulator->ports[n]; ... };
but they should otherwise generally be identical to the order they appear
in their respective ranges. Still, don't rely on that.

Input::id is gone. There was no point since we also got rid of the nasty
Input::order vector. Since I was in here, I went ahead and caved on the
pedantics and renamed Input::guid to Input::userData.

I removed the SNES controller port 1 multitap option. Basically, the only
game that uses this is N-warp Daisakusen and, no offense to d4s, it's
not really a good game anyway. It's just a quick demo to show 8-players
on the SNES. But in the UI, all it does is confuse people into wasting
time mapping a controller they're never going to use, and they're going
to wonder which port to use. If more compelling use cases for 8-players
comes about, we can reconsider this. I left all the code to support this
in place, so all you have to do is uncomment one line to enable it again.

We now have dsnes emulation! :D
If you change PPU::VRAM::size to 0x10000 (words), then you should now
have 128KiB of VRAM. Even better, it serializes the used-VRAM size,
so your save states shouldn't crash on you if you swap between the two
(though if you try this, you're nuts.)

Note that this option does break commercial software. Yoshi's Island in
particular. This game is setting A15 on some PPU register writes, but
not on others. The end result of this is things break horribly in-game.

Also, this option is causing a very tiny speed hit for obvious reasons
with the variable masking value (I'm even using size-1 for now.) Given
how niche this is, I may just leave it a compile-time constant to avoid
the overhead cost. Otherwise, if we keep the option, then it'll go into
Super Famicom.sys/manifest.bml ... I'll flesh that out in the near-future.

----

Finally, some fun for my OCD ... my monitor suddenly cut out on me
in the middle of working on this WIP, about six hours in of non-stop
work. Had to hit a bunch of ctrl+alt+fN commands (among other things)
and trying to log in headless on another TTY to do issue commands,
trying to recover the display. Finally power cycled the monitor and it
came back up. So all my typing ended up going to who knows where.

Usually this sort of thing terrifies me enough that I scrap a WIP and
start over to ensure I didn't screw anything up during the crashed screen
when hitting keys randomly.

Obviously, everything compiles and appears to work fine. And I know
it's extremely paranoid, but OCD isn't logical, so ... I'm going
to go over every line of the 100KiB r07->r08 diff looking for any
corruption/errors/whatever.

Changelog:
- (hopefully) fixed BS Memory and Sufami Turbo slot loading
- ported GB, GBA, WS cores to use nall/vfs
- completely removed loadRequest, saveRequest functionality from
  Emulator::Interface and ui-tomoko
  - loadRequest(folder) is now load(folder)
- save states now use a shared Emulator::SerializerVersion string
  - whenever this is bumped, all older states will break; but this makes
    bumping state versions way easier
  - also, the version string makes it a lot easier to identify
    compatibility windows for save states
- SNES PPU now uses uint16 vram[32768] for memory accesses [hex_usr]

NOTE: Super Game Boy loading is currently broken, and I'm not entirely
sure how to fix it :/
The file loading handoff was -really- complicated, and so I'm kind of
at a loss ... so for now, don't try it.
Everything else should theoretically work, so please report any bugs
you find.

So, this is pretty much it. I'd be very curious to hear feedback from
people who objected to the old nall/stream design, whether they are
happy with the new file loading system or think it could use further
improvements.

The 16-bit VRAM turned out to be a wash on performance (roughly the same
as before. 1fps slower on Zelda 3, 1fps faster on Yoshi's Island.) The
main reason for this was because Yoshi's Island was breaking horribly
until I changed the vramRead, vramWrite functions to take uint15 instead
of uint16.

I suspect the issue is we're using uint16s in some areas now that need
to be uint15, and this game is setting the VRAM address to 0x8000+,
causing us to go out of bounds on memory accesses.

But ... I want to go ahead and do something cute for fun, and just because
we can ... and this new interface is so incredibly perfect for it!! I
want to support an SNES unit with 128KiB of VRAM. Not out of the box,
but as a fun little tweakable thing. The SNES was clearly designed to
support that, they just didn't use big enough VRAM chips, and left one
of the lines disconnected. So ... let's connect it anyway!

In the end, if we design it right, the only code difference should be
one area where we mask by 15-bits instead of by 16-bits.

byuu says:

Changelog:
- improved attenuation of biquad filter by computing butterworth Q
  coefficients correctly (instead of using the same constant)
- adding 1e-25 to each input sample into the biquad filters to try and
  prevent denormalization
- updated normalization from [0.0 to 1.0] to [-1.0 to +1.0]; volume/reverb
  happen in floating-point mode now
- good amount of work to make the base Emulator::Audio support any number
  of output channels
  - so that we don't have to do separate work on left/right channels;
    and can instead share the code for each channel
- Emulator::Interface::audioSample(int16 left, int16 right); changed to:
  - Emulator::Interface::audioSample(double* samples, uint channels);
  - samples are normalized [-1.0 to +1.0]
  - for now at least, channels will be the value given to
    Emulator::Audio::reset()
- fixed GUI crash on startup when audio driver is set to None

I'm probably going to be updating ruby to accept normalized doubles as
well; but I'm not sure if I will try and support anything other 2-channel
audio output. It'll depend on how easy it is to do so; perhaps it'll be
a per-driver setting.

The denormalization thing is fierce. If that happens, it drops the
emulator framerate from 220fps to about 20fps for Game Boy emulation. And
that happens basically whenever audio output is silent. I'm probably
also going to make a nall/denormal.hpp file at some point with
platform-specific functionality to set the CPU state to "denormals as
zero" where applicable. I'll still add the 1e-25 offset (inaudible)
as another fallback.

- 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.

- SFC: fixed another bug with leap year months in SharpRTC emulation

- audio: implemented Emulator::Audio mixer and effects processor
- audio: implemented Emulator::Stream interface
  - it is now possible to have more than two audio streams: eg SNES
    + SGB + MSU1 + Voicer-Kun (eventually)
- audio: added reverb delay + reverb level settings; exposed balance
  configuration in UI
- video: reworked palette generation to re-enable saturation, gamma,
  luminance adjustments
- higan/emulator.cpp is gone since there was nothing left in it

I know you guys are going to say the color adjust/balance/reverb stuff
is pointless. And indeed it mostly is. But I like the idea of allowing
some fun special effects and configurability that isn't system-wide.

Note: there seems to be some kind of added audio lag in the SGB
emulation now, and I don't really understand why. The code should be
effectively identical to what I had before. The only main thing is that
I'm sampling things to 48000hz instead of 32040hz before mixing. There's
no point where I'm intentionally introducing added latency though. I'm
kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be
much appreciated :/

I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as
well, and that would be very bad.

Tim Allen 32a95a9761 Update to v097r12 release.
byuu says:

Nothing WS-related this time.

First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)

Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.

Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.

The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.

I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.

This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing
at the raw underlying state inside of various Game Boy core emulation
classes. So things are a lot better abstracted now.

Changelog:

- added Video Filter->Blur Emulation [1]
- added Video Filter->Scanline Emulation [2]
- improvements to GBA audio emulation (fixes Minish Cap) [Jonas Quinn]

[1] For the Famicom, this does nothing. For the Super Famicom, this
performs horizontal blending for proper pseudo-hires translucency. For
the Game Boy, Game Boy Color, and Game Boy Advance, this performs
interframe blending (each frame is the average of the current and
previous frame), which is important for things like the GBVideoPlayer.

[2] Right now, this only applies to the Super Famicom, but it'll come to
the Famicom in the future. For the Super Famicom, this option doesn't
just add scanlines, it simulates the phosphor decay that's visible in
interlace mode. If you observe an interlaced game like RPM Racing on
a real SNES, you'll notice that even on perfectly still screens, the
image appears to shake. This option emulates that effect.

Note 1: the buffering right now is a little sub-optimal, so there will
be a slight speed hit with this new support. Since the core is now
generating native ARGB8888 colors, it might as well call out to the
interface to lock/unlock/refresh the video, that way it can render
directly to the screen. Although ... that might not be such a hot idea,
since the GBx interframe blending reads from the target buffer, and that
tends to be a catastrophic option for performance.

Note 2: the balanced and performance profiles for the SNES are
completely busted again. This WIP took 6 1/2 hours, and I'm exhausted.
Very much not looking forward to working on those, since those two have
all kinds of fucked up speedup tricks for non-interlaced and/or
non-hires video modes.

Note 3: if you're on Windows and you saved your system folders somewhere
else, now'd be a good time to move them to %localappdata%/higan

This WIP finally achieves the vision I've had for icarus.

I also fixed a mapping issue with Cx4 that, oddly enough, only caused
the "2" from the Mega Man X2 title screen to disappear.

[Editor's note - "the vision for icarus" was described in a separate,
public forum post: http://board.byuu.org/phpbb3/viewtopic.php?p=20584
Quoting for posterity:

    icarus is now a full-fledged part of higan, and will be bundled with
    each higan WIP as well. This will ensure that in the future, the
    exact version of icarus you need to run higan will be included right
    along with it. As of this WIP, physical manifest files are now truly
    and entirely optional.

    From now on, you can associate your ROM image files with higan's
    main binary, or drop them directly on top of it, to load and play
    your games.

    Furthermore, there are two new menu options that appear under the
    library menu when icarus is present:

    - "Load ROM File ..." => gives you a single-file selection dialog to
      import (and if possible) run the game
    - "Import ROM Files ..." => gives you a multi-file import dialog
      with checkboxes to pull in multiple games at once

    Finally, as before, icarus can generate manifest.bml files for
    folders that lack them.

    For people who like the game folder and library system, nothing's
    changed. Keep using higan as you have been.

    For people who hate it, you can now use higan like your classic
    emulators. Treat the "Library->{System Name}" entries as your
    "favorites" list: the games you actually play. Treat the
    "Library->Load ROM" as your standard open file dialog in other
    emulators. And finally, treat "Advanced->Game Library" as your save
    data path for cheat codes, save states, save RAM, etc.
