Hi! I'm sick of playing on emulators using a crappy USB NES-controller so I've decided to buy a SNES console. I know there are huge differences between PAL and NTSC in NES Tetris, is this also the case when it comes to SNES Tetris & Dr. Mario? Living in Sweden it would be much more convenient getting a PAL console and PAL copy of Tetris & Dr. Mario but I obviously want to compete with the guys playing on the NTSC consoles. Any advice or information on the matter would be appreciated!
