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 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 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.

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 v087r17 release. byuu says: Emulated GBC sound plus the new extensions to it. I am kind of surprised by how little developers utilized the GBC audio portion. Mr. Driller now has sound effects, and Pinobee no Daibouken has BGM. I still have yet to emulate the GBA extra sound channels and PWM. Need to emulate timers and DMA 2 refresh mode before I can do that. Also, I moved both GBC and GBA audio to use length = data; if(++length == 0); rather than length = 64 - data; if(--length == 0); so that I could return literal values for register reads. I thought there was a good reason we used the latter version, but I can't hear any audible difference even in GBC games, so oh well. Lastly, I think the pattern[++offset] in the wave channel was a bug in the DMG/GBC only. I really, really hope it doesn't apply to the GBA, because that will make bank selection a serious pain in the ass.
