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 v103r07 release.
byuu says:
Changelog:
- gba/cpu: massive code cleanup effort
- gba/cpu: DMA can run in between active instructions¹
- gba/cpu: added two-cycle startup delay between DMA activation and
DMA transfers²
- processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle
- processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle
¹: unfortunately, this causes yet another performance penalty for the
poor GBA core =( Also, I think I may have missed disabling DMAs while
the CPU is stopped. I'll fix that in the next WIP.
²: I put the waiting counter decrement at the wrong place, so this
doesn't actually work. Needs to be more like
this:
auto CPU::step(uint clocks) -> void {
for(auto _ : range(clocks)) {
for(auto& timer : this->timer) timer.run();
for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--;
context.clock++;
}
...
auto CPU::DMA::run() -> bool {
if(cpu.stopped() || !active || waiting) return false;
transfer();
if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id;
if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge;
return true;
}
Of course, the real fix will be restructuring how DMA works, so that
it's always running in parallel with the CPU instead of this weird
design where it tries to run all channels in some kind of loop until no
channels are active anymore whenever one channel is activated.
Not really sure how to design that yet, however.

Update to v095r03 release and icarus 20151107.
byuu says:
Note: you will need the new icarus (and please use the "no manifest"
system) to run GBA games with this WIP.
Changelog:
- fixed caching of r(d) to pass armwrestler tests [Jonas Quinn]
- DMA to/from GBA BIOS should fail [Cydrak]
- fixed sign-extend and rotate on ldrs instructions [Cydrak]
- fixed 8-bit SRAM reading/writing [byuu]
- refactored GBA/cartridge
- cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash
- things won't crash horribly if you specify a RAM size larger than
the largest legal size in the manifest
- specialized MROM / SRAM classes replace all the shared read/write
functions that didn't work right anyway
- there's a new ruby/video.glx2 driver, which is not enabled by default
- use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet
- I'm not going to support OpenGL2 on Windows/OS X, because these OSes
don't ship ancient video card drivers
- probably more. What am I, clairvoyant? :P
For endrift's tests, this gets us to 1348/1552 memory and 1016/1260
timing. Overall, this puts us back in second place. Only no$ is ahead
on memory, but bgba is even more ahead on timing.

Update to 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
