Update to release v000r01. byuu says: Hooked up a scheduler to enter/exit the CPU core wherever I want. Added basic 4*1024*1024hz clock, and about eleven or so opcodes. Creating the disassembler as I encounter each new opcode, not skipping ahead to do all 'like other' opcodes, eg if I add 'dec b', I don't then add 'dec c' until I encounter it.

Update to v081r01 release. byuu says: - EI takes an extra cycle to raise IME; fixes Bubble Bobble [for the Gameboy], and likely many more games [Jonas Quinn] - nall/gameboy/cartridge.hpp descrambles MMM01 images (header can be at top or bottom of image now) - screenshot timestamps use filename-yyyy-mm-dd hh.mm.ss.bmp format; so that they can save on Windows - closing the emulator will switch to windowed mode first, so that geometry is preserved

cycle_edge();
Update to v083r07 release. byuu says: Game Boy: audio should sound a lot better, eg Zelda: DX first opening scene Game Boy Color: now uses cothread Processor::frequency to dynamically clock GB-CPU to 8MHz. Proper OAM DMA and timer speed. Fixes SMT: DC - WB audio. Added the break; statements to phoenix/windows/platform message loop Added audio latency/frequency to config file only
