Update to v106r10 release.
byuu says:
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.

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. |

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.

Update to v104r15 release.
byuu says:
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.

Update to v104r14 release.
byuu says:
Changelog:
- Emulator::Interface::videoResolution() -\> VideoResolution renamed
to videoInformation() -\> VideoInformation
- added double VideoInformation::refreshRate
- higan: added `binary := (application|library)` — set this to
`library` to produce a dynamic link library
- higan: removed `-march=native` for macOS application builds; and for
all library builds
- higan: removed `console` build flag; uncomment `link += -mwindows`
instead
- nall/GNUmakefile: `macosx` platform renamed `macos`
- still need to do this for nall/intrinsics.hpp
- Game Gear: return region=NTSC as the only option, so that the system
frequency is always set correctly
- hiro/cocoa: fixed typo [Sintendo]
- hiro/Windows: removed GetDpiForMonitor, as it's Windows 8+ only; DPI
is no longer per-monitor aware
- icarus: core Icarus class now has virtual functions for
directory::create, <file::exists>, <file::copy>, <file::write>
- icarus: Sufami Turbo can import save RAM files now
- icarus: setting `ICARUS_LIBRARY` define will compile icarus without
main(), GUI components
- ruby/video/Direct3D: choose the current monitor instead of top-left
monitor for fullscreen exclusive [Cydrak]
- ruby/video/Direct3D: do not set `WS_EX_TOPMOST` on fullscreen
exclusive window [Cydrak]
- this isn't necessary for exclusive mode, and it just makes
getting out of the application more difficult

Update to v104r13 release.
byuu says:
Changelog:
- nall/GNUmakefile: build=release changed to -O2, build=optimize is
now -O3
- hiro: added Monitor::dpi(uint index) → Position [returns logical
DPI for x, y]
- Position is a bad name, but dpi(monitor).(x,y)() make more sense
than .(width,height)()
- hiro: Position, Size, Geometry, Font changed from using signed int
to float
- hiro: Alignment changed from using double to float
- hiro: added skeleton (unused) Application::scale(), setScale()
functions
Errata:
- hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
with macOS' automatic scaling.
- hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
scaling
- hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
but I still use Qt 4.x)
- and just to get global DPI, hiro/qt's DPI retrieval has to use
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.

Update to v103r27 release.
byuu says:
Changelog:
- hiro/windows: set dpiAware=false, fixes icarus window sizes relative
to higan window sizes
- higan, icarus, hiro, ruby: add support for high resolution displays
on macOS [ncbncb]
- processor/lr35902-legacy: removed
- processor/arm7tdmi: new processor core started; intended to one day
be a replacement for processor/arm
It will probably take several WIPs to get the new ARM core up and
running. It's the last processor rewrite. After this, all processor
cores will be up to date with all my current programming conventions.

Update to v103r24 release.
byuu says:
Changelog:
- gb/mbc6: mapper is now functional, but Net de Get has some text
corruption¹
- gb/mbc7: mapper is now functional²
- gb/cpu: HDMA syncs other components after each byte transfer now
- gb/ppu: LY,LX forced to zero when LCDC.d7 is lowered (eg disabled),
not when it's raised (eg enabled)
- gb/ppu: the LCD does not run at all when LCDC.d7 is clear³
- fixes graphical corruption between scene transitions in Legend
of Zelda - Oracle of Ages
- thanks to Cydrak, Shonumi, gekkio for their input on the cause
of this issue
- md/controller: renamed "Gamepad" to "Control Pad" per official
terminology
- md/controller: added "Fighting Pad" (6-button controller) emulation
[hex\_usr]
- processor/m68k: fixed TAS to set data.d7 when
EA.mode==DataRegisterDirect; fixes Asterix
- hiro/windows: removed carriage returns from mouse.cpp and
desktop.cpp
- ruby/audio/alsa: added device driver selection [SuperMikeMan]
- ruby/audio/ao: set format.matrix=nullptr to prevent a crash on some
systems [SuperMikeMan]
- ruby/video/cgl: rename term() to terminate() to fix a crash on macOS
[Sintendo]
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.

Update to v103r23 release.
byuu says:
Changelog:
- gb: added accelerometer X-axis, Y-Axis inputs¹
- gb: added rumble input¹
- gb/mbc5: added rumble support²
- gb/mbc6: added skeleton driver, but it doesn't boot Net de Get
- gb/mbc7: added mostly complete driver (only missing EEPROM), but it
doesn't boot Kirby Tilt 'n' Tumble
- gb/tama: added leap year assignment
- tomoko: fixed macOS compilation [MerryMage]
- hiro/cocoa: fix table cell redrawing on updates and automatic column
resizing [ncbncb]
- hiro/cocoa: fix some weird issue with clicking table view checkboxes
on Retina displays [ncbncb]
- 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.

- hiro/windows: fix bug that was preventing the escape key from
closing some dialog windows
- nall/registry: use "\\\\" as separator instead of "/" ... because
some registry keys contain "/" in them >_>

Update to v103r13 release.
byuu says:
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 >_>

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.

Update to v103 WIP release.
byuu says (in the WIP forum):
Changelog:
- higan: cheat codes accept = and ? separators now
- the new preferred code format is: address=value or
address=if-match?value
- the old code format of address/value and address/if-match/value
will continue to work
- higan: cheats.bml is no longer included with the base distribution
- mightymo stopped updating it in 2015, and it's not source code;
it can still be pulled in from older releases
- 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
Drive core. This is what happens when I have 47 things I have to do,
given how lousy my memory is. I miss things.

Update to v102r06 release.
byuu says:
Changelog:
- added higan/emulator/platform.hpp (moved out Emulator::Platform from
emulator/interface.hpp)
- moved gmake build paramter to nall/GNUmakefile; both higan and
icarus use it now
- added build=profile mode
- MD: added the region select I/O register
- MD: started to add region selection support internally (still no
external select or PAL support)
- PCE: added cycle stealing when reading/writing to the VDC or VCE;
and when using ST# instructions
- PCE: cleaned up PSG to match the behavior of Mednafen (doesn't
improve sound at all ;_;)
- note: need to remove loadWaveSample, loadWavePeriod
- HuC6280: ADC/SBC decimal mode consumes an extra cycle; does not set
V flag
- HuC6280: block transfer instructions were taking one cycle too many
- icarus: added code to strip out PC Engine ROM headers
- hiro: added options support to BrowserDialog
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.

Update to v102r02 release.
byuu says:
Changelog:
- I caved on the `samples[] = {0.0}` thing, but I'm very unhappy about it
- if it's really invalid C++, then GCC needs to stop accepting it
in strict `-std=c++14` mode
- Emulator::Interface::Information::resettable is gone
- Emulator::Interface::reset() is gone
- FC, SFC, MD cores updated to remove soft reset behavior
- split GameBoy::Interface into GameBoyInterface,
GameBoyColorInterface
- split WonderSwan::Interface into WonderSwanInterface,
WonderSwanColorInterface
- PCE: fixed off-by-one scanline error [hex_usr]
- PCE: temporary hack to prevent crashing when VDS is set to < 2
- hiro: Cocoa: removed (u)int(#) constants; converted (u)int(#)
types to (u)int_(#)t types
- icarus: replaced usage of unique with strip instead (so we don't
mess up frameworks on macOS)
- 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.

Update to v101r19 release.
byuu says:
Changelog:
- added \~130 new PAL games to icarus (courtesy of Smarthuman
and aquaman)
- added all three Korean-localized games to icarus
- sfc: removed SuperDisc emulation (it was going nowhere)
- sfc: fixed MSU1 regression where the play/repeat flags were not
being cleared on track select
- nall: cryptography support added; will be used to sign future
databases (validation will always be optional)
- minor shims to fix compilation issues due to nall changes
The real magic is that we now have 25-30% of the PAL SNES library in
icarus!
Signing will be tricky. Obviously if I put the public key inside the
higan archive, then all anyone has to do is change that public key for
their own releases. And if you download from my site (which is now over
HTTPS), then you don't need the signing to verify integrity. I may just
put the public key on my site on my site and leave it at that, we'll
see.

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.

Update to v101r05 release.
byuu says:
Changelog:
- 68K: fixed bug that affected BSR return address
- VDP: added very preliminary emulation of planes A, B, W (W is
entirely broken though)
- VDP: added command/address stuff so you can write to VRAM, CRAM,
VSRAM
- VDP: added VRAM fill DMA
I would be really surprised if any commercial games showed anything at
all, so I'd probably recommend against wasting your time trying, unless
you're really bored :P
Also, I wanted to add: I am accepting patches\! So if anyone wants to
look over the 68K core for bugs, that would save me untold amounts of
time in the near future :D

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?

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. |

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

But even though I'm not assigning any special significance to this version, we should probably test it more thoroughly first. |

- 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

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.

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.

For now, just resize the icarus window to get it to use the full window width for list view items. |

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. |

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.

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 |

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. |

Update to v096r03 release.
byuu says: 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 - GB: system uses open collector logic, so unmapped reads return 0xFF, not 0x00 (passes blargg's cpu_instrs again) [gekkio] |

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 |

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.

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. |

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. |

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.

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. |

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.

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. |

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.

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

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. |

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.
