Mario RPG

can we play mario RPG ( the supernintendo game ) in the R4 ????? ;D

No.

I guess you can try. The SNES Emulator for DS isn't the best. Some games work and some don't. You won't be losing anything if you tried.Look here for the SNES Emulator:https://www.romulation.org/forum/index.php?topic=5002.0

Super Mario RPG is not supported by the DS SNES emulators.
