no$gba 2.7a


no$gba a is a Nintendo GameBoy Advance & Nintendo DS emulator / debugger for Windows and DOS. No$gba features multiplayer support. It is currently the fastest working GBA emulator, as it can run most games at full speed on a computer with an Intel Pentium or faster processor.

This is due to it being written entirely in 80x86 assembly. It is also the only working GBA or NDS emulator for MS-DOS.
