I'm 99% sure that using component cables bypasses the difference in colour modulation for NTSC and PAL, so all you would need is a TV that can display at 60Hz, which should be common enough...you can play NTSC copies of brawl on a PAL wii, you just need to use geckoOS (which apparently will be an option for the demo/final release). Oh and an NTSC compatable tv, otherwise the picture is black and white
