Changelog:

  - nall/GNUmakefile: fixed findstring parameter arguments [Screwtape]
  - nall/Windows: always include -mthreads -lpthread for all
    applications
  - nall/memory: code restructuring

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

Tim Allen 6524a7181d 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.

Changelog:

  - gba,ws: removed Thread::step() override¹
  - processor/m68k: move.b (a7)+ and move.b (a7)- adjust a7 by two, not
    by one²
  - tomoko: created new initialize(Video,Audio,Input)Driver() functions³
  - ruby/audio: split Audio::information into
    Audio::available(Devices,Frequencies,Latencies,Channels)³
  - ws: added Model::(WonderSwan,WonderSwanColor,SwanCrystal)()
    functions for consistency with other cores

¹: this should hopefully fix GBA Pokemon Pinball. Thanks to
SuperMikeMan for pointing out the underlying cause.

²: this fixes A Ressaha de Ikou, Mega Bomberman, and probably more
games.

³: this is the big change: so there was a problem with WASAPI where
you might change your device under the audio settings panel. And your
new device may not support the frequency that your old device used. This
would end up not updating the frequency, and the pitch would be
distorted.

The old Audio::information() couldn't tell you what frequencies,
latencies, or channels were available for all devices simultaneously, so
I had to split them up. The new initializeAudioDriver() function
validates you have a correct driver, or it defaults to none. Then it
validates a correct device name, or it defaults to the first entry in
the list. Then it validates a correct frequency, or defaults to the
first in the list. Then finally it validates a correct latency, or
defaults to the first in the list.

In this way ... we have a clear path now with no API changes required to
select default devices, frequencies, latencies, channel counts: they
need to be the first items in their respective lists.

So, what we need to do now is go through and for every audio driver that
enumerates devices, we need to make sure the default device gets added
to the top of the list. I'm ... not really sure how to do this with most
drivers, so this is definitely going to take some time.

Also, when you change a device, initializeAudioDriver() is called again,
so if it's a bad device, it will disable the audio driver instead of
continuing to send samples at it and hoping that the driver blocked
those API calls when it failed to initialize properly.

Now then ... since it was a decently-sized API change, it's possible
I've broken compilation of the Linux drivers, so please report any
compilation errors so that I can fix them.

Changelog:

  - gb/cpu: force STAT mode to 0 when LCD is disabled (fixes Pokemon
    Pinball, etc)
  - gb/ppu: when LCD is disabled, require at least one-frame wait to
    re-enable, display white during this time
      - todo: should step by a scanline at a time: worst-case is an
        extra 99% of a frame to enable again
  - gba/ppu: cache tilemap lookups and attribute parsing
      - it's more accurate because the GBA wouldn't read this for every
        pixel
      - but unfortunately, this didn't provide any speedup at all ...
        sigh
  - ruby/audio/alsa: fixed const issue with free()
  - ruby/video/cgl: removed `glDisable(GL_ALPHA_TEST)` [deprecated]
  - ruby/video/cgl: removed `glEnable(GL_TEXTURE_2D)` [unnecessary as
    we use shaders]
  - processor/lr35902: started rewrite¹

¹: so, the Game Boy and Game Boy Color cores will be completely
broken for at least the next two or three WIPs.

The old LR35902 was complete garbage, written in early 2011. So I'm
rewriting it to provide a massive cleanup and consistency with other
processor cores, especially the Z80 core.

I've got about 85% of the main instructions implemented, and then I have
to do the CB instructions. The CB instructions are easier because
they're mostly just a small number of opcodes in many small variations,
but it'll still be tedious.

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.

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.

Tim Allen e1223366a7 Update to v103r22 release.
byuu says:

Changelog:

  - ruby: ported all remaining drivers to new API¹
  - ruby/wasapi: fix for dropping one sample per period [SuperMikeMan]
  - gb: emulated most of the TAMA RTC; but RTC state is still volatile²

¹: the new ports are:

  - audio/{directsound, alsa, pulseaudio, pulseaudiosimple, ao}
  - input/{udev, quartz, carbon}

It's pretty much guaranteed many of them will have compilation errors.
Please paste the error logs and I'll try to fix them up. It may take a
WIP or two to get there.

It's also possible things broke from the updates. If so, I could use
help comparing the old file to the new file, looking for mistakes, since
I can't test on these platforms apart from audio/directsound.

Please report working drivers in this list, so we can mark them off the
list. I'll need both macOS and Linux testers.

audio/directsound.cpp:112:

    if(DirectSoundCreate(0, &_interface, 0) != DS_OK) return terminate(), false;

²: once I get this working, I'll add load/save support for the RTC
values. For now, the RTC data will be lost when you close the emulator.

Right now, you can set the date/time in real-time mode, and when you
start the game, the time will be correct, and the time will tick
forward. Note that it runs off emulated time instead of actual real
time, so if you fast-forward to 300%, one minute will be 20 seconds.

The really big limitation right now is that when you exit the game, and
restart it, and resume a new game, the hour spot gets corrupted, and
this seems to instantly kill your pet. Fun. This is crazy because the
commands the game sends to the TAMA interface are identical between
starting a new game and getting in-game versus loading a game.

It's likely going to require disassembling the game's code and seeing
what in the hell it's doing, but I am extremely bad at LR35092 assembly.
Hopefully endrift can help here :|

Changelog:

  - ruby/audio/xaudio2: ported to new ruby API
  - ruby/video/cgl: ported to new ruby API (untested, won't compile)
  - ruby/video/directdraw: ported to new ruby API
  - ruby/video/gdi: ported to new ruby API
  - ruby/video/glx: ported to new ruby API
  - ruby/video/wgl: ported to new ruby API
  - ruby/video/opengl: code cleanups

The macOS CGL driver is sure to have compilation errors. If someone will
post the compilation error log, I can hopefully fix it in one or two
iterations of WIPs.

I am unable to test the Xorg GLX driver, because my FreeBSD desktop
video card drivers do not support OpenGL 3.2. If the driver doesn't
work, I'm going to need help tracking down what broke from the older
releases.

The real fun is still yet to come ... all the Linux-only drivers, where
I don't have a single Linux machine to test with.

Todo:

  - libco/fiber
  - libco/ucontext (I should really just delete this)
  - tomoko: hide main UI window when in exclusive fullscreen mode

Tim Allen 8be474b0ac Update to v103r19 release.
byuu says:

Changelog:

  - tomoko: Application::onMain assigned at end of Program::Program()
    [Screwtape]¹
  - libco: add `#define _XOPEN_SOURCE 500` to fix compilation of sjlj.c
    [Screwtape]
  - ruby/audio/openal: fixed device driver string list enumeration
  - ruby/audio/wasapi: changing device re-initializes the driver now
  - ruby/audio/wasapi: probably a pointless change, but don't fill the
    buffer beyond the queue size with silence
  - ruby/video/xvideo: renamed from ruby/video/xv
  - ruby/video/xvideo: check to see if `XV_AUTOPAINT_COLORKEY` exists
    before setting it [SuperMikeMan]
  - ruby/video/xvideo: align buffer sizes to be evenly divisible by four
    [SuperMikeMan]
  - ruby/video/xvideo: fail nicely without crashing (hopefully)
  - ruby/video/xvideo: add support for YV12 and I420 12-bit planar YUV
    formats²

¹: prevents crashes when drivers fail to initialize from running the
main loop that polls input drivers before the input driver is
initialized (or fails to initialize itself.) Some drivers still don't
block their main functions when initialization fails, so they will still
crash, but I'll work to fix them.

²: this was a **major** pain in the ass, heh. You only get one chroma
sample for every four luma samples, so the color reproduction is even
worse than UYVY and YUYV (which is two to four chroma to luma.) Further,
the planar format took forever to figure out. Apparently it doesn't care
what portion of the image you specify in XvShmPutImage, it expects you
to use the buffer dimensions to locate the U and V portions of the data.

This is probably the most thorough X-Video driver in existence now.

Notes:

  - forgot to rename the configuration settings dialog window title to
    just "Settings"

Changelog:

  - tomoko: improved handling of changing audio devices on the audio
    settings panel
  - ruby/audio/wasapi: added device enumeration and selection support¹
  - ruby/audio/wasapi: release property store handle from audio device
  - ruby/audio/wasapi: fix exclusive mode buffer filling
  - ruby/video/glx2: ported to new API -- tested and confirmed working
    great²
  - ruby/video/sdl: fixed initialization -- tested and confirmed working
    on FreeBSD now³
  - ruby/video/xv: ported to new API -- tested and mostly working great,
    sans fullscreen mode⁴

Errata:

  - accidentally changed "Driver Settings" label to "Driver" on the
    audio settings tab because I deleted the line and forgot the
    "Settings" part
  - need to use "return initialize();" from setDevice() in the WASAPI
    driver, instead of "return true;", so device selection is currently
    not functioning in this WIP for said driver

¹: for now, this will likely end up selecting the first available
endpoint device, which is probably wrong. I need to come up with a
system to expose good 'default values' when selecting new audio drivers,
or changing audio device settings.

²: glx2 is a fallback driver for system with only OpenGL 2.0 and no
OpenGL 3.2 drivers, such as FreeBSD 10.1 with AMD graphics cards.

³: although I really should track down why InputManager::poll() is
crashing the emulator when Video::ready() returns false ...

⁴: really bizarrely, when entering fullscreen mode, it looks like the
image was a triangle strip, and the bottom right triange is missing, and
the top left triangle skews the entire image into it. I'm suspecting
this is a Radeon driver bug when trying to create a 2560x1600 X-Video
surface. The glitch persists when exiting fullscreen, too.

If anyone can test the X-Video driver on their Linux/BSD system, it'd be
appreciated. If it's just my video card, I'll ignore it. If not,
hopefully someone can find the cause of the issue :|

Tim Allen 0b4e7fb5a5 Update to v103r17 release.
byuu says:

Changelog:

  - tomoko: re-hid the video sync option¹
  - tomoko: removed " Settings" duplication on all the individual
    settings tab options
  - ruby/audio/wasapi: finished port to new syntax; adapted to an
    event-driven model; support 32-bit integral audio²
  - ruby/video/sdl: ported to new syntax; disabled driver on FreeBSD³

¹: still contemplating a synchronize submenu of {none, video, audio},
but ... the fact that video can't work on PAL, WonderSwan games is a
real limitation for it

²: this driver actually received a ton of work. There's also a new
ring-buffer queue, and I added special handling for when exclusive mode
fails because the latency requested is lower than the hardware can
support. It'll pick the closest latency to the minimum that is possible
in this case.

On my Audigy Rx, the results for non-exclusive mode are the same. For
exclusive mode, the framerate drops from 60fps to ~50fps for smaller
buffers, and ~55fps for larger buffers (no matter how big, it never hits
60fps.) This is a lot better than before where it was hitting ~15fps,
but unfortunately it's the best I can do.

The event system used by WASAPI is really stupid. It just uses SetEvent
at some arbitrary time, and you have to query to see how many samples
it's waiting on. This makes it unknowable how many samples we should
buffer before calling `WaitForSingleObject(INFINITE)`, and it's also
unclear how we should handle cases where there's more samples available
than our queue has: either we can fill it with zeroes, or we can write
less samples. The former should prevent audio looping effects when
running too slowly, whereas the latter could potentially be too
ambitious when the audio could've recovered from a minor stall.

It's shocking to me how there's as many ways to send audio to a sound
card as there are sound card APIs, when all that's needed is a simple
double buffer and a callback event from another thread to do it right.
It's also terrifying how unbelievably shitty nearly all sound card
drivers apparently are.

Also, I don't know if cards can output an actual 24-bit mode with three
byte audio samples, or if they always just take 32-bit samples and
ignore the lower 8-bits. Whatever, it's all nonsense for the final
output to be >16-bits anyway (hi, `double[]` input from ruby.)

³: unfortunately, this driver always crashes on FreeBSD (even before
the rewrite), so I'll need someone on Linux to test it and make sure it
actually works. I'll also need testing for a lot of the other drivers as
well, once they're ported over (I don't have X-video, PulseAudio, ALSA,
or udev.)

Note that I forgot to set `_ready=true` at the end of `initialize()`,
and `_ready=false` in `terminate()`, but it shouldn't actually matter
beyond showing you a false warning message on startup about it failing
to initialize.

  - tomoko: Settings→Configuration expanded to Settings→{Video,
    Audio, Input, Hotkey, Advanced} Settings²

  - ruby/audio/openal: ported to new API; added device selection support
  - ruby/audio/wasapi: ported to new API, but did not test yet (it's
    assuredly still broken)⁴

¹: I'm uneasy about this ... but, I guess if people want to disable
audio and just have smooth scrolling video ... so be it. With
Screwtape's documentation, hopefully that'll help people understand that
video synchronization always breaks audio synchronization. I may change
this to a child menu that lets you pick between {no synchronization,
video synchronization, audio synchronization} as a radio selection.

²: given how much more useful the video and audio tabs are now, I
felt that four extra menu items were worth saving a click and going
right to the tab you want. This also matches the behavior of the Tools
menu displaying all tool options and taking you directly to each tab.
This is kind of a hard change to get used to ... but I think it's for
the better.

³: kind of stupid because I've never seen a hardware sound card where
floor(frequency) != frequency, but whatever. Yay consistency.

⁴: I'm going to move it to be event-driven, and try to support 24-bit
sample formats if possible. Who knows which cards that'll fix and which
cards that'll break. I may end up making multiple WASAPI drivers so
people can find one that actually works for them. We'll see.

Changelog:

  - ruby: rewrote the API interfaces for Video, Audio, Input
  - ruby/audio: can now select the number of output channels (not useful
    to higan, sorry)
  - ruby/asio: various improvements
  - tomoko: audio settings panel can now select separate audio devices
    (for ASIO, OSS so far)
  - tomoko: audio settings panel frequency and latency lists are
    dynamically populated now

Note: due to the ruby API rewrite, most drivers will not compile. Right
now, the following work:

  - video: Direct3D, XShm
  - audio: ASIO, OSS
  - input: Windows, SDL, Xlib

It takes a really long time to rewrite these (six hours to do the
above), so it's going to be a while before we're back at 100%
functionality again.

Errata:

  - ASIO needs device(), setDevice()
  - need to call setDevice() at program startup to populate
    frequency/latency settings properly
  - changing the device and/or frequency needs to update the emulator
    resampler rates

The really hard part is going to be the last one: the only way to change
the emulator frequency is to flush all the audio streams and then
recompute all the coefficients for the resamplers. If this is called
during emulation, all audio streams will be erased and thus no sound
will be output. I'll most likely be forced to simply ignore
device/frequency changes until the user loads another game. It is at
least possible to toggle the latency dynamically.

Changelog:

  - tomoko: by popular choice, default to adaptive mode on new installs
  - 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 >_>
  - ruby: add ASIO driver stub (so far it can only initialize and grab
    the driver name/version information)

Tim Allen ffd150735b Update to v101r07 release.
byuu says:

Added VDP sprite rendering. Can't get any games far enough in to see if
it actually works. So in other words, it doesn't work at all and is 100%
completely broken.

Also added 68K exceptions and interrupts. So far only the VDP interrupt
is present. It definitely seems to be firing in commercial games, so
that's promising. But the implementation is almost certainly completely
wrong. There is fuck all of nothing for documentation on how interrupts
actually work. I had to find out the interrupt vector numbers from
reading the comments from the Sonic the Hedgehog disassembly. I have
literally no fucking clue what I0-I2 (3-bit integer priority value in
the status register) is supposed to do. I know that Vblank=6, Hblank=4,
Ext(gamepad)=2. I know that at reset, SR.I=7. I don't know if I'm
supposed to block interrupts when I is >, >=, <, <= to the interrupt
level. I don't know what level CPU exceptions are supposed to be.

Also implemented VDP regular DMA. No idea if it works correctly since
none of the commercial games run far enough to use it. So again, it's
horribly broken for usre.

Also improved VDP fill mode. But I don't understand how it takes
byte-lengths when the bus is 16-bit. The transfer times indicate it's
actually transferring at the same speed as the 68K->VDP copy, strongly
suggesting it's actually doing 16-bit transfers at a time. In which case,
what happens when you set an odd transfer length?

Also, both DMA modes can now target VRAM, VSRAM, CRAM. Supposedly there's
all kinds of weird shit going on when you target VSRAM, CRAM with VDP
fill/copy modes, but whatever. Get to that later.

Also implemented a very lazy preliminary wait mechanism to to stall out
a processor while another processor exerts control over the bus. This
one's going to be a major work in progress. For one, it totally breaks
the model I use to do save states with libco. For another, I don't
know if a 68K->VDP DMA instantly locks the CPU, or if it the CPU could
actually keep running if it was executing out of RAM when it started
the DMA transfer from ROM (eg it's a bus busy stall, not a hard chip
stall.) That'll greatly change how I handle the waiting.

Also, the OSS driver now supports Audio::Latency. Sound should be
even lower latency now. On FreeBSD when set to 0ms, it's absolutely
incredible. Cannot detect latency whatsoever. The Mario jump sound seems
to happen at the very instant I hear my cherry blue keyswitch activate.

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

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.

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

Small catch: need to capture layout resize events internally in Windows
to call resizeColumns. For now, just resize the icarus window to get it
to use the full window width for list view items.

Tim Allen 7cdae5195a Update to v098r07 release.
byuu says:

Changelog:
- GB: support modeSelect and RAM for MBC1M (Momotarou Collection)
- audio: implemented native resampling support into Emulator::Stream
- audio: removed nall::DSP completely

Unfortunately, the new resampler didn't turn out quite as fast as I had
hoped. The final hermite resampling added some overhead; and I had to
bump up the kernel count to 500 from 400 to get the buzzing to go away
on my main PC. I think that's due to it running at 48000hz output
instead of 44100hz output, maybe?

Compared to Ryphecha's:
(NES) Mega Man 2: 167fps -> 166fps
(GB) Mega Man II: 224fps -> 200fps
(WSC) Riviera: 143fps -> 151fps

Odd that the WS/WSC ends up faster while the DMG/CGB ends up slower.

But this knocks 922 lines down to 146 lines. The only files left in all
of higan not written (or rewritten) by me are ruby/xaudio2.h and
libco/ppc.c

Changelog:
- WS/WSC: re-added support for screen rotation (code is inside WS core)
- ruby: changed sample(uint16_t left, uint16_t right) to sample(int16_t
  left, int16_t right);
  - requires casting to uint prior to shifting in each driver, but
    I felt it was misleading to use uint16_t just to avoid that
- ruby: WASAPI is now built in by default; has wareya's improvements,
  and now supports latency adjust
- tomoko: audio settings panel has new "Exclusive Mode" checkbox for
  WASAPI driver only
  - note: although the setting *does* take effect in real-time, I'd
    suggest restarting the emulator after changing it
- tomoko: audio latency can now be set to 0ms (which in reality means
  "the minimum supported by the driver")
- all: increased cothread size from 512KiB to 2MiB to see if it fixes
  bullshit AMD driver crashes
  - this appears to cause a slight speed penalty due to cache locality
    going down between threads, though

byuu says:

Changelog:
- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
  merged to SFC::Cothread
  - Cothread here just means "Thread with CPU affinity" (couldn't think
    of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
  - this is the beginning of work to allow expansion port devices to be
    dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
  no frequency is assigned
  - note: the WASAPI driver can default to whatever the native frequency
    is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
  it will display the frequency used)
- tomoko: removed the timing settings panel
  - the goal is to work toward smooth video via adaptive sync
  - the model is broken by not being in control of the audio frequency
    anyway
  - it's further broken by PAL running at 50hz and WSC running at 75hz
  - it was always broken anyway by SNES interlace timing varying from
    progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
  and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
  (libco, emulator, audio, video)

The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.

Tim Allen 29be18ce0c Update to v097r17 release.
byuu says:

Changelog:
- ruby: if DirectSoundCreate fails (no sound device present), return
  false from init instead of crashing
- nall: improved edge case return values for
  (basename,pathname,dirname,...)
- nall: renamed file_system_object class to inode
- nall: varuint_t replaced with VariadicNatural; which contains
  .bit,.bits,.byte ala Natural/Integer
- nall: fixed boolean compilation error on Windows
- WS: popa should not restore SP
- GBA: rewrote the CPU/APU cores to use the .bit,.bits functions;
  removed registers.cpp from each

Note that the GBA changes are extremely major. This is about five hours
worth of extremely delicate work. Any slight errors could break
emulation in extremely bad ways. Let's hold off on extensive testing
until the next WIP, after I do the same to the PPU.

So far ... endrift's SOUNDCNT_X I/O test is failing, although that code
didn't change, so clearly I messed up SOUNDCNT_H somehow ...

To compile on Windows:

1. change nall/string/platform.hpp line 47 to

    return slice(result, 0, 3);

2. change ruby/video.wgl.cpp line 72 to

    auto lock(uint32_t*& data, uint& pitch, uint width, uint height) -> bool {

3. add this line to the very top of hiro/windows/header.cpp:

    #define boolean FuckYouMicrosoft

Changelog:
- added nall/GNUmakefile unique() function; used on linking phase of
  higan
- added nall/unique_pointer
- target-tomoko and {System}::Video updated to use
  unique_pointer<ClassName> instead of ClassName* [1]
- locate() updated to search multiple paths [2]
- GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs
- FC, GB, GBA: merge video/ into the PPU cores
- ruby: fixed ~AudioXAudio2() typo

[1] I expected this to cause new crashes on exit due to changing the
order of destruction of objects (and deleting things that weren't
deleted before), but ... so far, so good. I guess we'll see what crops
up, especially on OS X (which is already crashing for unknown reasons on
exit.)

[2] right now, the search paths are: programpath(), {configpath(),
"higan/"}, {localpath(), "higan/"}; but we can add as many more as we
want, and we can also add platform-specific versions.

byuu says:

Changelog:
- added preliminary WASAPI driver (it's really terrible, though. Patches
  most welcome.)
- all of processor/ updated to auto fn() -> ret syntax
- all of gb/ updated to auto fn() -> ret syntax

If you want to test the WASAPI driver, then edit ui-tomoko/GNUmakefile,
and replace audio.xaudio2 with audio.wasapi Note that the two drivers
are incompatible and cannot co-exist (yet. We can probably make it work
in the future.)

All that's left for the auto fn() -> ret syntax is the NES core and the
balanced/performance SNES components. This is kind of a big deal because
this syntax change causes diffs between WIPs to go crazy. So the sooner
we get this done and out of the way, the better. It's also nice from
a consistency standpoint, of course.

Tim Allen e0815b55b9 Update to v094r28 release.
byuu says:

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

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

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

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

Tim Allen bb3c69a30d Update to v094r25 release.
byuu says:

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

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

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

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

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

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

byuu says:

Finally!! Compilation works once again on Windows.

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

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

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

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

And probably lots more.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Changelog:
- added SA-1 MDR; fixes bug in SD Gundam G-Next where the main
  battleship was unable to fire
- added out-of-the-box support for any BSD running Clang 3.3+ (FreeBSD
  10+, notably)
- added new video shader, "Display Emulation", which changes the shader
  based on the emulated system
- fixed the home button to go to your default library path
- phoenix: Windows port won't send onActivate unless an item is selected
  (prevents crashing on pressing enter in file dialog)
- ruby: removed vec4 position from out Vertex {} (helps AMD cards)
- shaders: updated all shaders to use texture() instead of texture2D()
  (helps AMD cards)

The "Display Emulation" option works like this: when selected, it tries
to load "<path>/Video Shaders/Emulation/<systemName>.shader/"; otherwise
it falls back to the blur shader. <path> is the usual (next to binary,
then in <config>/higan, then in /usr/share/higan, etc); and <systemName>
is "Famicom", "Super Famicom", "Game Boy", "Game Boy Color", "Game Boy
Advance"

To support BSD, I had to modify the $(platform) variable to
differentiate between Linux and BSD.
As such, the new $(platform) values are:
win -> windows
osx -> macosx
x -> linux or bsd

I am also checking uname -s instead of uname -a now. No reason to
potentially match the hostname to the wrong OS type.

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.
2013-08-18 13:21:14 +10:00
Tim Allen a59ecb3dd4 Include all the code from the bsnes v068 tarball.
byuu describes the changes since v067:

This release officially introduces the accuracy and performance cores,
alongside the previously-existing compatibility core. The accuracy core
allows the most accurate SNES emulation ever seen, with every last
processor running at the lowest possible clock synchronization level.
The performance core allows slower computers the chance to finally use
bsnes. It is capable of attaining 60fps in standard games even on an
entry-level Intel Atom processor, commonly found in netbooks.

The accuracy core is absolutely not meant for casual gaming at all. It
is meant solely for getting as close to 100% perfection as possible, no
matter the cost to speed. It should only be used for testing,
development or debugging.

The compatibility core is identical to bsnes v067 and earlier, but is
now roughly 10% faster. This is the default and recommended core for
casual gaming.

The performance core contains an entirely new S-CPU core, with
range-tested IRQs; and uses blargg's heavily-optimized S-DSP core
directly. Although there are very minor accuracy tradeoffs to increase
speed, I am confident that the performance core is still more accurate
and compatible than any other SNES emulator. The S-CPU, S-SMP, S-DSP,
SuperFX and SA-1 processors are all clock-based, just as in the accuracy
and compatibility cores; and as always, there are zero game-specific
hacks. Its compatibility is still well above 99%, running even the most
challenging games flawlessly.

If you have held off from using bsnes in the past due to its system
requirements, please give the performance core a try. I think you will
be impressed. I'm also not finished: I believe performance can be
increased even further.

I would also strongly suggest Windows Vista and Windows 7 users to take
advantage of the new XAudio2 driver by OV2. Not only does it give you
a performance boost, it also lowers latency and provides better sound by
way of skipping an API emulation layer.

Changelog:
- Split core into three profiles: accuracy, compatibility and
  performance
- Accuracy core now takes advantage of variable-bitlength integers (eg
  uint24_t)

Tim Allen cda10094da Updated to v067r22 release.
byuu says:

Added OV2's XAudio2 driver (it's better and faster than the DirectSound
one)
Fixed DirectInput keypad number codes
Added launcher to make the profiles work
Profiles now called: Accuracy, Compatibility, Performance (not debating
names anymore)

The launcher isn't going to work on OS X because of the .app folder
bullshit (yes, yes, .sfc folders.)
It also crashes on Windows XP for god only knows what reason. Works fine
on Windows 7 and Linux. So XP users, rename the .dll files to .exe to
test this release. I'll fix it on Monday.
The color highlighting fucks up the radio boxes on the Windows classic
theme, because Nokia can't afford a god damn QA team.
Lastly, I forgot to add launcher to the make archive-all command, so the
source for it will be in the next WIP.
