fixGB Alpha v0.8 is released. This is still quite early in development so it cant do all that much, its essentially the GB version of my NES Emulator fixNES. If you want to check it out for some reason I do include a windows binary in the "Releases" tab, if you want to compile it go check out the "build" files. You will need freeglut as well as openal-soft to compile the project, it should run on most systems since it is fairly generic C code. Right now most standard GB titles using MBC1, 3 and 5 should work just fine and also save into standard .sav files. You can also listen to .gbs files by dragging them in, changing tracks works by pressing left/right.

fixGB Alpha v0.8 Changelog:
-fixed playback for some gbs music files
-implemented APU zombie mode for volume control
-corrected several CPU instruction timing details
-properly implemented OAM DMA with all its timings etc
-corrected some memory bugs and improved timer accuracy
-added basic serial I/O control support as some games rely on its interrupt
-improved PPU accuracy and implemented STAT DMC bug required for some games

Controls right now are keyboard only and do the following:
Y/Z is A
X is B
A is Start
S is select
Arrow Keys is DPad
Keys 1-9 integer-scale the window to number
P is Pause
