DSBoy - Gameboy Emulator for Nintendo DS

mateom199 posted this news/release:

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.

Nice that someone is working on a Game Boy emulator for the DS! If I had the resources to assist, I would try to help.

Keep up the work, and good luck.

this is great news. i wish i knew how to program so i could help. a gameboy emulator is the biggest glaring hole in the DS homebrew scene, so it's awesome to see this is finally getting off the ground.

Question - is it possible to emulate GBA games/programs on the DS?

For that matter, is it possible to emulate 32X games (don't ask)?

Yes, there are alot of emulators and porgrams for Game Boy Advance working on the Nintendo DS.

No. You will see NEVER a 32X emulator on the Nintendo DS. It's impossible.

the ds already runs gba software flawlessly, the only possible use for a gba emulator really would be piracy as far as I can see.

- i patch the "DSBoy.nds" with DLDI patcher ... then drag and drop it into my microSD ... then i put few roms "SMB.gb" ... and when i launch the emulator from my DS ... the DSBoy loader dont show any kinda roms ... only folders ... i'm using a M3 DS simply
