desmume

DeSmuME is a freeware emulator for the NDS roms & Nintendo DS Lite games created by YopYop156 and now maintained by the TASvideos team. It supports many homebrew nds rom demoes as well as a handful of Wireless Multiboot demo nds roms. DeSmuME is also able to emulate nearly all of the commercial nds rom titles which other DS Emulators aren't.
