NES/SNES rom on DS???

Can i play NES/SNES game rom on my DS? How can i running it, using emulator? Im using EDGE. Do i just copied the emulator and the NES/SNES game to my microSD? Thx....

Yes you can! Just get an emulator: like this one for NES, and this one for SNES, then just copy the emulators and roms to your microSD card and you're done.

the snes emulator runs games pretty poorly at the moment

Depends what game. Only really has a few layer issues.

yeah i played mario and a few others fine, but not alot else
