DSBoy - Gameboy Emulator for Nintendo DS

Hoping to stir up some interest in this NDS GB/GB emulator, I added libfat support to it, with a pretty rudimentary file explorer (thanks to PicoDriveDS) and adjusted a few lines of code so it will compile with DKP r20.

It seems that theres a bug somewhere in the code causing slightly corrupt
graphics, I wasn't able to track it down but I haven't been looking for very long.

Unfortunately, I know little asm and even less about the Gameboy's Z80 processor, so I don't imagine I would be much help in coding speed optimizations and the such. Hopefully someone with more knowledge on the the subject can help improve this emulator.

attached is both the modified source and a binary (.nds and nds.gba).

KNOWN ISSUES:
Graphics slightly corrupt
Many ROMs will crash it - tested with Mega Man 1, works fine (slow though)
ROM's must end in ".gbc", spaces in filenames not tested.
