Update to v098r01 release. 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.

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.

static auto Enter() -> void;
Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

auto main() -> void;
Update to v091r13 release, and ananke v00r01. byuu says (about higan): - dropped release/ root node for individual games (still there in ananke's database.) - Memory export uses smarter names (vram.rwm -> video.ram, etc.) - cheat database moved from XML to BML (3.1MB to 1.9MB file size.) - cheat codes moved from XML to BML - resource manifest moved from XML to BML What can I say, I like consistency. But I'll leave the shaders alone until I get around to shader folders. byuu says (about ananke): Works with higan v091r13. Only does SNES stuff so far.

Update to v097r15 release. byuu says: Changelog: - higan now uses Natural<Size>/Integer<Size> for its internal types - Super Famicom emulation now uses uint24 instead of uint for bus addresses (it's a 24-bit bus) - cleaned up gb/apu MMIO writes - cleaned up sfc/coprocessor/msu1 MMIO writes - ~3% speed penalty I've wanted to do that 24-bit bus thing for so long, but have always been afraid of the speed impact. It's probably going to hurt balanced/performance once they compile again, but it wasn't significant enough to harm the accuracy core's frame rate, thankfully. Only lost one frame per second. The GBA core handlers are clearly going to take a lot more work. The bit-ranges will make it substantially easier to handle, though. Lots of 32-bit registers where certain values span multiple bytes, but we have to be able to read/write at byte-granularity.

Update to v074 release. byuu says (since v073): This release adds full low-level emulation of the NEC uPD96050 coprocessor, used by the ST-0010 (F1 Race of Champions II) and the ST-0011 (Hayazashi Nidan Morita Shougi). The former was already playable with HLE, but lacked timing emulation. The latter has never been playable through emulation before now. But as with SD Gundam GX before, you really weren't missing much. [...] Also new in this release is my own Game Boy emulator. It is being used to provide native Super Game Boy support, built directly into bsnes. This core is released under the GPLv2, but I am willing to grant a more permissive license for other SNES emulators, if anyone is interested. Of course I cannot compete with the quality of gambatte, and certainly not from only a weeks' worth of work. Currently, there is no Game Boy-side sound output and there are quite a few bugs remaining in its emulation core. I would appreciate any help on this, the Game Boy is not my forte. So yes, we are taking a step back today, so that we may take two steps forward in the future. [...] Lastly, the debugger is still Linux-only, but it is now stable enough to be considered usable. Check it out if you like, compile with -DDEBUGGER to enable it.
