Update to v103r09 release.
byuu says:
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.

Update to v103r08 release.
byuu says:
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

Update to v102r22 release.
byuu says:
Changelog:
- higan: Emulator::Interface::videoSize() renamed to videoResolution()
- higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize()
- higan: added video display rotation support to Video
- GBA: substantially improved audio mixing
- fixed bug with FIFO 50%/100% volume setting
- now properly using SOUNDBIAS amplitude to control output
frequencies
- reduced quantization noise
- corrected relative volumes between PSG and FIFO channels
- both PSG and FIFO values cached based on amplitude; resulting in
cleaner PCM samples
- treating PSG volume=3 as 200% volume instead of 0% volume now
(unverified: to match mGBA)
- GBA: properly initialize ALL CPU state; including the vital
prefetch.wait=1 (fixes Classic NES series games)
- GBA: added video rotation with automatic key translation support
- PCE: reduced output resolution scalar from 285x242 to 285x240
- the extra two scanlines won't be visible on most TVs; and they
make all other cores look worse
- this is because all other cores output at 240p or less; so they
were all receiving black bars in windowed mode
- tomoko: added "Rotate Display" hotkey setting
- tomoko: changed hotkey multi-key logic to OR instead of AND
- left support for flipping it back inside the core; for those so
inclined; by uncommenting one line in input.hpp
- tomoko: when choosing Settings→Configuration, it will
automatically select the currently loaded system
- for instance, if you're playing a Game Gear game, it'll take you
to the Game Gear input settings
- if no games are loaded, it will take you to the hotkeys panel
instead
- WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls
into combined "Hardware"
- WS(C): converted rotation support from being inside the core to
using Emulator::Video
- this lets WS(C) video content scale larger now that it's not
bounded by a 224x224 square box
- WS(C): added automatic key rotation support
- WS(C): removed emulator "Rotate" key (use the general hotkey
instead; I recommend F8 for this)
- nall: added serializer support for nall::Boolean (boolean) types
- although I will probably prefer the usage of uint1 in most cases

Update to v102r13 release.
byuu says:
Changelog:
- removed Emulator::Interface::videoFrequency(), audioFrequency()¹
- (MS,GG,MD)/PSG: removed inversion on noise channel LFSR update
[mic_]
- MD/PSG: lowered volume to match YM2612 volume
- MD/YM2612: added Cydrak's emulation of FM channels and LFO²
¹: These were no longer used by the UI. The video frequency is
adaptive on many systems. And the audio frequency is meaningless due to
Emulator::Audio always outputting a consistent frequency specified by
the UI. Plus, take the Genesis where there's two sound chips running at
different frequencies. So, these had to go.
²: Due to some lurking bugs, the audio is completely broken
unfortunately. Will need to be debugged :(
First pass looking for any typos didn't yield any obvious results.

Update to v102r10 release.
byuu says: Changelog: - removed Emulator::Interface::Capabilities¹ - MS: improved the PSG emulation a bit - MS: added cheat code support - MS: added save state support² - MD: emulated the PSG³ ¹: there's really no point to it anymore. I intend to add cheat codes to the GBA core, as well as both cheat codes and save states to the Mega Drive core. I no longer intend to emulate any new systems, so these values will always be true. Further, the GUI doesn't respond to these values to disable those features anymore ever since the hiro rewrite, so they're double useless. ²: right now, the Z80 core is using a pointer for HL-\>(IX,IY) overrides. But I can't reliably serialize pointers, so I need to convert the Z80 core to use an integer here. The save states still appear to work fine, but there's the potential for an instruction to execute incorrectly if you're incredibly unlucky, so this needs to be fixed as soon as possible. Further, I still need a way to serialize array<T, Size> objects, and I should also add nall::Boolean serialization support. ³: I don't have a system in place to share identical sound chips. But this chip is so incredibly simple that it's not really much trouble to duplicate it. Further, I can strip out the stereo sound support code from the Game Gear portion, so it's even tinier. Note that the Mega Drive only just barely uses the PSG. Not at all in Altered Beast, and only for a tiny part of the BGM music on Sonic 1, plus his jump sound effect. |

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.

Changelog:
- converted Emulator::Interface::Bind to Emulator::Platform
- temporarily disabled SGB hooks
- SMS: emulated Game Gear palette (latching word-write behavior not
implemented yet)
- SMS: emulated Master System 'Reset' button, Game Gear 'Start' button
- SMS: removed reset() functionality, driven by the mappable input now
instead

I'm not sure what's causing the SMS\<-\>GG switch bug, having a hard
time debugging it. Help would be very much appreciated, if anyone's up
for it. Otherwise I'll keep trying to track it down on my end.

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 v099r08 release.
byuu says:
Changelog:
- nall/vfs work 100% completed; even SGB games load now
- emulation cores now call load() for the base cartridges as well
- updated port/device handling; portmask is gone; device ID bug should
be resolved now
- SNES controller port 1 multitap option was removed
- 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.

Update to v099r07 release.
byuu says:
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.

- 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.

Update to v098r06 release.
byuu says:
Changelog:
- emulation cores now refresh video from host thread instead of
cothreads (fix AMD crash)
- SFC: fixed another bug with leap year months in SharpRTC emulation
- SFC: cleaned up camelCase on function names for
armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes
- GB: added MBC1M emulation (requires manually setting mapper=MBC1M in
manifest.bml for now, sorry)
- 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.

Update to v098r04 release.
byuu says: Changelog: - SFC: fixed behavior of 21fx $21fe register when no device is connected (must return zero) - SFC: reduced 21fx buffer size to 1024 bytes in both directions to mirror the FT232H we are using - SFC: eliminated dsp/modulo-array.hpp [1] - higan: implemented higan/video interface and migrated all cores to it [2] [1] the echo history buffer was 8-bytes, so there was no need for it at all here. Not sure what I was thinking. The BRR buffer was 12-bytes, and has very weird behavior ... but there's only a single location in the code where it actually writes to this buffer. It's much easier to just write to the buffer three times there instead of implementing an entire class just to abstract away two lines of code. This change actually boosted the speed from ~124.5fps to around ~127.5fps, but that's within the margin of error for GCC. I doubt it's actually faster this way. The DSP core could really use a ton of work. It comes from a port of blargg's spc_dsp to my coding style, but he was extremely fond of using 32-bit signed integers everywhere. There's a lot of opportunity to remove red tape masking by resizing the variables to their actual state sizes. I really need to find where I put spc_dsp6.sfc from blargg. It's a great test to verify if I've made any mistakes in my implementation that would cause regressions. Don't suppose anyone has it? [2] so again, the idea is that higan/audio and higan/video are going to sit between the emulation cores and the user interfaces. The hope is to output raw encoding data from the emulation cores without having to worry about the video display format (generally 24-bit RGB) of the host display. And also to avoid having to repeat myself with eg three separate implementations of interframe blending, and so on. Furthermore, the idea is that the user interface can configure its side of the settings, and the emulation cores can configure their sides. Thus, neither has to worry about the other end. And now we can spin off new user interfaces much easier without having to mess with all of these things. Right now, I've implemented color emulation, interframe blending and SNES horizontal color bleed. I did not implement scanlines (and interlace effects for them) yet, but I probably will at some point. Further, for right now, the WonderSwan/Color screen rotation is busted and will only show games in the horizontal orientation. Obviously this must be fixed before the next official release, but I'll want to think about how to implement it. Also, the SNES light gun pointers are missing for now. Things are a bit messy right now as I've gone through several revisions of how to handle these things, so a good house cleaning is in order once everything is feature-complete again. I need to sit down and think through how and where I want to handle things like light gun cursors, LCD icons, and maybe even rasterized text messages. And obviously ... higan/audio is still just nall::DSP's headers. I need to revamp that whole interface. I want to make it quite powerful with a true audio mixer so I can handle things like SNES+SGB+MSU1+Voicer-Kun+SNES-CD (five separate audio streams at once.) The video system has the concept of "effects" for things like color bleed and interframe blending. I want to extend on this with useful other effects, such as NTSC simulation, maybe bringing back my mini-HQ2x filter, etc. I'd also like to restore the saturation/gamma/luma adjustment sliders ... I always liked allowing people to compensate for their displays without having to change settings system-wide. Lastly, I've always wanted to see some audio effects. Although I doubt we'll ever get my dream of CoreAudio-style profiles, I'd like to get some basic equalizer settings and echo/reverb effects in there. |

Update to 20160215 release.
byuu says: Got it. Wow, that didn't hurt nearly as much as I thought it was going to. Dropped from 127.5fps to 123.5fps to use Natural/Integer for (u)int(8,16,32,64). That's totally worth the cost. |

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. |

Update to v097r05 release.
byuu says: More V30MZ implemented, a lot more to go. icarus now supports importing WS and WSC games. It expects them to have the correct file extension, same for GB and GBC. > Ugh, apparently HiDPI icarus doesn't let you press the check boxes. I set the flag value in the plist to false for now. Forgot to do it for higan, but hopefully I won't forget before release. |

Update to v096r07 release.
byuu says: Changelog: - configuration files are now stored in localpath() instead of configpath() - Video gamma/saturation/luminance sliders are gone now, sorry - 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 |

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 v093 release.
byuu says: Changelog: - added Cocoa target: higan can now be compiled for OS X Lion [Cydrak, byuu] - SNES/accuracy profile hires color blending improvements - fixes Marvelous text [AWJ] - fixed a slight bug in SNES/SA-1 VBR support caused by a typo - added support for multi-pass shaders that can load external textures (requires OpenGL 3.2+) - added game library path (used by ananke->Import Game) to Settings->Advanced - system profiles, shaders and cheats database can be stored in "all users" shared folders now (eg /usr/share on Linux) - all configuration files are in BML format now, instead of XML (much easier to read and edit this way) - main window supports drag-and-drop of game folders (but not game files / ZIP archives) - audio buffer clears when entering a modal loop on Windows (prevents audio repetition with DirectSound driver) - a substantial amount of code clean-up (probably the biggest refactoring to date) One highly desired target for this release was to default to the optimal drivers instead of the safest drivers, but because AMD drivers don't seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD has too big a market share. Hopefully with v093 officially released, we can get some public input on what AMD doesn't like. |

Update to v092r08 release.
byuu says: Changelog: - fixed cartridge load window focus on Windows - lots of updates to nall, ruby and phoenix - ethos and Emulator::Interface updated from "foo &bar" to "foo& bar" syntax (work-in-progress) Before I had mixed the two ways to declare variables/arguments all over the place, so the goal is to unify them all for consistency. So the changelog for this release will be massive (750KB >.>) due to the syntax change. Yeah, that's what I spent the last three days working on ... |

Update to higan v092r01, ananke v02r01 and purify v03r01 releases.
byuu says: higan changelog: - compiler is set to g++-4.7, subst(cc,++) rule is gone, C files compile with $(compiler) -x c - make throws an error when you specify an invalid profile or compile on an unsupported platform (instead of hanging forever) - added unverified.png to resources (causes too big of a speed hit to actually check for folder/unverified file ... so disabled for now) - fixed default browser paths for Game Boy, Sufami Turbo and BS-X Satellaview (have to delete paths.cfg to see this) - browser home button seeks to configpath()/higan/library.cfg - settings->driver is now settings->advanced, and it adds game library path setting and profile information - emulation cores now load manifest files internally, manifest.bml is not required for a game folder to be recognized by higan as such - BS-X Satellaview and Sufami Turbo slot cartridge handling moved out of sfc/chip and into sfc/slot - Video::StartFullScreen only sets fullscreen when a game is specified on the command-line purify and ananke changelog: - library output path shown in purify window - added button to change library path - squelch firmware warning windows to prevent multi-threading crash, but only via purify (they show up in higan still) |

Update to higan v091r14 and ananke v00r03 releases.
byuu says:
higan changelog:
- generates title displayed in emulator window by asking the core
- core builds title solely from "information/title" ... if it's not
there, you don't get a title at all
- sub-system load menu is gone ... since there are multiple revisions of
the SGB, this never really worked well anyway
- to load an SGB, BS-X or ST cartridge, load the base cartridge first
- "File->Load Game" moved to "Load->Import Game" ... may cause a bit of
confusion to new users, but I don't like having a single-item menu,
we'll just have to explain it to new users
- browser window redone to look like ananke
- home button here goes to ~/Emulation rather than just ~ like ananke,
since this is the home of game folders
- game folder icon is now the executable icon for the Tango theme
(orange diamond), meant to represent a complete game rather than
a game file or archive
ananke changelog:
- outputs GBC games to "Game Boy Color/" instead of "Game Boy/"
- adds the file basename to "information/title"
Known issues:
- using ananke to load a GB game trips the Super Famicom SGB mode and
fails (need to make the full-path auto-detection ignore non-bootable
systems)
- need to dump and test some BS-X media before releasing
- ananke lacks BS-X Satellaview cartridge support
- v092 isn't going to let you retarget the ananke/higan game folder path
of ~/Emulation, you will have to wait for a future version if that
bothers you so greatly
[Later, after the v092 release, byuu posted this additional changelog:
- kill laevateinn
- add title()
- add bootable, remove load
- combine file, library
- combine [][][] paths
- fix SFC subtype handling XML->BML
- update file browser to use buttons
- update file browser keyboard handling
- update system XML->BML
- fix sufami turbo hashing
- remove Cartridge::manifest

Update to higan v091 release.
byuu says: Basically just a project rename, with s/bsnes/higan and the new icon from lowkee added in. It won't compile on Windows because I forgot to update the resource.rc file, and a path transform command isn't working on Windows. It was really just meant as a starting point, so that v091 WIPs can flow starting from .00 with the new name (it overshadows bsnes v091, so publicly speaking this "shouldn't exist" and will probably be deleted from Google Code when v092 is ready.) |
