Update to v087r26 release.
byuu says:
Changelog:
- fixed FIFO[1] reset behavior (fixes audio in Sword of Mana)
- added FlashROM emulation (both sizes)
- GBA parses RAM settings from manifest.xml now
- save RAM is written to disk now
- added save state support (it's currently broken, though)
- fixed ROM/RAM access timings
- open bus should mostly work (we don't do the PC+12 stuff yet)
- emulated the undocumented memory control register (mirror IWRAM,
disable I+EWRAM, EWRAM wait state count)
- emulated keypad interrupts
- emulated STOP (freezes video, audio, DMA and timers; only breaks on
keypad IRQs)
- probably a lot more, it was a long night ...
Show stoppers, missing things, broken things, etc:
- ST018 is still completely broken
- GBC audio sequencer apparently needs work
- GBA audio FIFO buffer seems too quiet
- PHI / ROM prefetch needs to be emulated (no idea on how to do this,
especially PHI)
- SOUNDBIAS 64/128/256khz modes should output at that resolution
(really, we need to simulate PWM properly, no idea on how to do this)
- object mosaic top-left coordinates are wrong (minor, fixing will
actually make the effect look worse)
- need to emulate PPU greenswap and color palette distortion (no idea on
how do this)
- need GBA save type database (I would also LIKE to blacklist
/ patch-out trainers, but that's a discussion for another day.)
- some ARM ops advance the prefetch buffer, so you can read PC+12 in
some cases

Update to v102r19 release.
byuu says:
Note: add `#undef OUT` to the top of higan/gba/ppu/ppu.hpp to compile on
Windows (ugh ...) Now to await posts about this in four more threads
again ;)
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.

Update to v087r26 release.
byuu says:
Changelog:
- fixed FIFO[1] reset behavior (fixes audio in Sword of Mana)
- added FlashROM emulation (both sizes)
- GBA parses RAM settings from manifest.xml now
- save RAM is written to disk now
- added save state support (it's currently broken, though)
- fixed ROM/RAM access timings
- open bus should mostly work (we don't do the PC+12 stuff yet)
- emulated the undocumented memory control register (mirror IWRAM,
disable I+EWRAM, EWRAM wait state count)
- emulated keypad interrupts
- emulated STOP (freezes video, audio, DMA and timers; only breaks on
keypad IRQs)
- probably a lot more, it was a long night ...
Show stoppers, missing things, broken things, etc:
- ST018 is still completely broken
- GBC audio sequencer apparently needs work
- GBA audio FIFO buffer seems too quiet
- PHI / ROM prefetch needs to be emulated (no idea on how to do this,
especially PHI)
- SOUNDBIAS 64/128/256khz modes should output at that resolution
(really, we need to simulate PWM properly, no idea on how to do this)
- object mosaic top-left coordinates are wrong (minor, fixing will
actually make the effect look worse)
- need to emulate PPU greenswap and color palette distortion (no idea on
how do this)
- need GBA save type database (I would also LIKE to blacklist
/ patch-out trainers, but that's a discussion for another day.)
- some ARM ops advance the prefetch buffer, so you can read PC+12 in
some cases

Update to v102r19 release.
byuu says:
Note: add `#undef OUT` to the top of higan/gba/ppu/ppu.hpp to compile on
Windows (ugh ...) Now to await posts about this in four more threads
again ;)
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.
