Update to v074r08 release. byuu says: The nall::function binding for the memory map apparently breaks when the debugger is enabled, as PPU:: becomes PPUdebugger::, etc; and C++ isn't smart enough to upconvert for us. Not sure how I am going to work around that yet ... Changelog: - improved GameBoy::CPU::Halt emulation, fixes Legend of Zelda intro water+world-map scrolling at the same time - added GameBoy::APU skeleton, and hooked up MMIO read/write for all registers - modified nall integer->string functions

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.

s.array(mmio_data);
s.integer(counter);
s.integer(sequencer);
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.
