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:

  - 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

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:

  - emulator/random: new array function with more realistic RAM
    initializations
  - emulator/random: both low and high entropy register initializations
    now use PCG
  - gba/player: rumble will time out and disable after being left on for
    500ms; fixes Pokemon Pinball issue
  - ruby/input/udev: fixed rumble effects [ma\_rysia]
  - sfc/system: default to low-entropy randomization of memory

The low-entropy memory randomization is modeled after one of my SHVC
2/1/3 systems. It generates striped patterns in memory, using random
inputs (biased to 0x00/0xff), and has a random chance of corrupting 1-2
bits of random values in the pool of memory (to prevent easy emulator
detection and to match observed results on hardware.)

The reasoning for using PCG on register initializations, is that I don't
believe they're going to have repeating patterns like RAM does anyway.
And register initializations are way more vital.

I want to have the new low-entropy RAM mode tested, so at least for the
next few WIPs, I've set the SNES randomization over to low-entropy.
We'll have to have a long discussion and decide whether we want official
releases to use high-entropy or low-entropy.

Also, I figured out the cause of the Prince of Persia distortion ... I
had the volume under the audio settings tab set to 200%. I didn't
realize there were SNES games that clipped so easily, given how
incredibly weak SNES audio is compared to every other sound source on my
PC. So with no entropy or low-entropy, indeed the game now sounds just
fine.

I can't actually test the udev fixes, so I guess we'll see how that goes
for Screwtape and ma\_rysia.

Tim Allen d060904b8d Revert an accidental ruby change.

  - 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.

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.

    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),

        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

    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/mbc5: added rumble support²
  - gb/mbc6: added skeleton driver, but it doesn't boot Net de Get

  - 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.

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 :|

  - ruby/video/gdi: ported to new ruby API
  - ruby/video/glx: 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

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"

  - ruby/audio/wasapi: release property store handle from audio device
  - ruby/audio/wasapi: fix exclusive mode buffer filling

  - 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 :|

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.

  - 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.

Tim Allen 4129630d97 Update to v103r15 release.
byuu says:

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

byuu says:

Changelog:

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

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

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

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

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

Note: add `#undef OUT` to the top of higan/gba/ppu/ppu.hpp to compile on

Changelog:

  - GBA: rewrote PPU from a scanline-based renderer to a pixel-based
    renderer
  - ruby: fixed video/gdi bugs

Note that there's an approximately 21% speed penalty compared to v102r18
for the pixel-based renderer.

Also, horizontal mosaic effects are not yet implemented. But they should
be prior to v103. This one is a little tricky as it currently works on
fully rendered scanlines. I need to roll the mosaic into the background
renderers, and then for sprites, well ... see below.

The trickiest part by far of this new renderer is the object (sprite)
system. Unlike every other system I emulate, the GBA supports affine
rendering of its sprites. Or in other words, rotation effects. And it
also has a very complex priority system.

Right now, I can't see any way that the GBA PPU could render pixels in
real-time like this. My belief is that there's a 240-entry buffer that
fills up the next scanline's row of pixels. Which means it probably also
runs on the last scanline of Vblank so that the first scanline has
sprite data.

However, I didn't design my object renderer like this just yet. For now,
it creates a buffer of all 240 pixels right away at the start of the
scanline. I know\!\! That's technically scanline-based. But it's only
for fetching object tiledata, and it's only temporary.

What needs to happen is I need a way to run something like a "mini libco
thread" inside of the main thread, so that the object renderer can run
in parallel with the rest of the PPU, yet not be a hideous abomination
of a state machine, yet also not be horrendously slow as a full libco
thread would be.

I'm envisioning some kind of stackless yielding coroutine. But I'll need
to think through how to design that, given the absence of coroutines
even in C++17.

Tim Allen 2fbbccf985 Update to v101r16 release.
byuu says:

Changelog:

  - Z80: implemented 113 new instructions (all the easy
    LD/ADC/ADD/AND/OR/SBC/SUB/XOR ones)
  - Z80: used alternative to castable<To, With> type (manual cast inside
    instruction() register macros)
  - Z80: debugger: used register macros to reduce typing and increase
    readability
  - Z80: debugger: smarter way of handling multiple DD/FD prefixes
    (using gotos, yay!)
  - ruby: fixed crash with Windows input driver on exit (from SuperMikeMan)

I have no idea how the P/V flag is supposed to work on AND/OR/XOR, so
that's probably wrong for now. HALT is also mostly a dummy function for
now. But I typically implement those inside instruction(), so it
probably won't need to be changed? We'll see.
2016-09-06 10:09:33 +10:00
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.
2016-08-15 14:56:38 +10:00
Tim Allen 07995c05a5 Update to v100 release.
byuu says:

higan has finally reached v100!

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

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

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

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

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

Changelog (since v099r16 open beta):

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

Errata:

- forgot to remove the " - Slot A", " - Slot B" suffixes for Sufami
  Turbo slot loading
  - this means you have to navigate up one folder and then into Sufami
    Turbo/ to load games for this system
- moving WonderSwan orientation controls to the device slot is causing
  some nastiness
  - can now select orientation from the main menu, but it doesn't rotate
    the display

- higan/tomoko: allow loading files via icarus on the command-line

- higan/tomoko: (begrudging) quick hack to fix presentation window focus
  on startup
- higan/audio: don't divide output audio volume by number of streams
- processor/r65816: fix a regression in (read,write)DB; fixes Taz-Mania
- fixed compilation regressions on Windows and Linux

I'm happy with where we are at with code cleanups and stability, so I'd
like to release v100. But even though I'm not assigning any special
significance to this version, we should probably test it more thoroughly
first.

- 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;

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.

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.

  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 0955295475 Update to v098r08 release.
byuu says:

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

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

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

The S-DD1 changes mean you need to update your installation of icarus
again. Also, even though the Lunar FMV never really worked on the
accuracy core anyway (it didn't initialize the PPU properly), it really
won't work now that we emulate the hard-limit of 16MiB for S-DD1 games.

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

  - 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

  - 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)

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

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

Tim Allen 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

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

This is a few days old, but oh well.

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

I'm slowly pushing for (u)int(8,16,32,64) to use my custom
Integer<Size>/Natural<Size> classes instead. But it's going to be one
hell of a struggle to get that into higan.

Tim Allen 344e63d928 Update to v097r02 release.
byuu says:

Note: balanced/performance profiles still broken, sorry.

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.

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

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

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

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

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

Installation Commands:

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

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

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

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

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

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

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

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

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

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

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

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

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

byuu says about r13:

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

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

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

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

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

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

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

byuu says about r14:

    r14 work:

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

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

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

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

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

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

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

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

byuu says about r15:

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

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

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

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

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

Tim Allen a219f9c121 Update to v095r08 release.
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.
2015-11-21 18:36:48 +11:00
Tim Allen 40f4b91000 Update to v095r06 release.
byuu says:

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

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

Errata:
- forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor,
  which makes Super Scope / Justifier crash. Will be fixed in the next
  WIP.

Tim Allen 0fe55e3f5b Update to v095r03 release and icarus 20151107.
byuu says:

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

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

For endrift's tests, this gets us to 1348/1552 memory and 1016/1260
timing. Overall, this puts us back in second place. Only no$ is ahead
on memory, but bgba is even more ahead on timing.
2015-11-10 22:11:29 +11:00
Tim Allen b42ab2fcb3 Update to v095r02 release.
byuu says:

Aspect correction is fixed now. Works way better than in v095 official.

It's still force-enabled in fullscreen mode. The idea of disabling it is
that it looks bad at 2x scale. But when you're fullscreen with a minimum
of 4x scale, there's no reason not to enable it.

It won't turn on at all for GB/C/A anymore. And I dropped the cute
attempt at making the aspect prettier on 2560x1600 monitors, so it'll be
the stock 8:7 across the board now for S/NES.

Also, the aspect correction will affect the window even when a game's
not loaded now, so the size won't bounce around as you change games in
windowed mode between GB/C/A and S/NES.

...

I also enhanced the ruby/glx driver. It won't crash if OpenGL 3.2 isn't
available anymore (fails safely ... had to capture the Xlib error
handler to suppress that), and it defaults to the MESA glXSwapInterval
before the SGI version. Because apparently the MESA version defines the
SGI version, but makes it a no-op. What. The. Fuck. right? But whatever,
reordering the enumerations fixes the ability to toggle Vsync on AMD
GPUs now.

...

Video shaders are back again. If you are using the OpenGL driver, you'll
see a "Video Shaders" menu beneath the "Video Filters" menu (couldn't
merge it with the filters due to hiro now constructing menu ordering
inside the header files. This works fine though.)

You want either "higan.exe" + "Video Shaders/" or "~/.local/bin/tomoko"
+ "~/.local/tomoko/Video Shaders/"

Tim Allen c45633550e Update to v094r42 release.
byuu says:

- Video scale settings modified from {1x,2x,3x} to {2x,3x,4x}
- System menu now renames to active emulation core
- Added fast forward hotkey

Not changing for v095:

Tim Allen 1b0b54a690 Update to v094r38 release.
byuu says:

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

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

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

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

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

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

I forgot to do that, and too lazy to upload another WIP.
2015-07-14 19:32:43 +10:00
Tim Allen ea02f1e36a Update to v094r31 release.
byuu says:

This WIP scores 448/920 tests passed.

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

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

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

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

In other news ...

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

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

I added DT_NOPREFIX so the Windows ListView will show & characters
correctly now.
2015-06-25 19:52:32 +10:00
Tim Allen 83f684c66c Update to v094r29 release.
byuu says:

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

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

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

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

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

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

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

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