I decided to get it after I was playing it with a person I know on their GameCube. (Yes, I was playing a Gamecube, at least it's not an X-Box, right? GameCubes aren't that bad...)
Anyways, I managed to find an NTSC/US version (a lot were NTSC/JP and my Dreamcast isn't chipped) Apparently the game is even jump-pack compatible. :)
