Update to v075r04 release. byuu says: Changelog: - hooked up everything necessary for Game Boy sound emulation ... - bgameboy and bsnes/SGB input 4MHz frequency, and output 44.1KHz frequency (produces soft static for now, to verify it is working) - rewrote all of gameboy/apu, it now has a 4MHz worker thread, and separate classes/folders for each channel+master, and serializes So it's basically all I can do without actual emulation code or human-readable documentation/example code.

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.

Update to v096r04 release. byuu says: Changelog: - fixed S-DD1 RAM writes (Star Ocean audio fixed) - applied all of the DMG test ROM fixes discussed earlier; passes many more test ROMs now - at least until the GBVideoPlayer is working: for debugging purposes, CPU/PPU single-step now instead of sync just-in-time (~30% slower) - fixed OS X crash on NSTextView (hopefully, would be very odd if not) Unfortunately passing these test ROMs caused my favorite GB/GBC game to break all of its graphics =( Shin Megami Tensei - Devichil - Kuro no Sho (Japan) is all garbled now. I'm really quite bummed by this ... but I guess I'll go through and revert r04's fixes one at a time until I find what's causing it. On the plus side, Astro Rabby is playable now. Still acts weird when pressing B/A on the first screen, but the start button will start the game. EDIT: got it. Shin Megami Tensei - Devichil requires FF4F (VBK) to be readable. Before, it was always returning 0x00. With my return 0xFF patch, that broke. But it should be returning the VBK value, which also fixes it. Also need to handle FF68/FF6A reads. Was really hoping that'd help GBVideoPlayer too, but nope. It doesn't read any of those three registers.

Update to v082r02 release. byuu says: Has Jonas Quinn's many Game Boy APU fixes, and two more from blargg's notes that I added. It also has the new dynamic phoenix. So yeah, it'll crash on bsnes/Qt exit. If anyone can fix it *properly* and wants the money, I'll pay them $20 for the trouble =)

Update to v082r03 release. byuu says: Couple more fixes to audio from Jonas, and I converted all types from "unsigned" to the smallest sizes possible, which simplified a bit of the code. Love variable-length integers. Audio core should be really good now. Not perfect, but pretty close for 99% of games. Also fixed the window stuff for Cool World and such.

Update to v075r05 release. byuu says: Added Game Boy sound emulation, all four channels. It's really, really, really bad. Plenty of bugs, I don't even know what the fuck a high-pass filter is so that isn't there. Hermite resampling from 4MHz down to 44KHz. But it's tolerable. I don't understand what sweep is for at all, and I'm sure I have that insane recursive reload behavior wrong. This is pretty much my own design. I referenced blargg's gb snd emu, blargg's older gb apu ref, Cydrak's APU core, that lousy gbdev wiki article, the completely and utterly worthless pandocs, and received nothing but bad and wrong information that just wasted my time from But I managed to pull it off. It's also painfully slow, like 250fps on my machine slow. Countless optimizations are possible.
