i got this rom for 3 different systems, SNES, SMS and C64 so i can play it on my DS but neither of them work. the SNES version shows the title then crashes, the SMS version puts up a gameboy screen (as if i just loaded a GBA game)and crashes. and i couldnt get the C64 version to work at all. can anyone help me out here, i'd really like to play this game again on my DS.
