I'm interested in what the fastest version is, and if there is anything wrong with the xbox version of the game. I don't see any times submitted on that platform.

I don't run this game but I've played the XBOX version and I've seen the other versions and I can say that it is the slowest version due to longer long time which is super weird. Even PS2 seems to have faster loads than XBOX. Another thing I've gathered from different versions is that it takes longer to reset the game after finishing an episode depending on your console. GC is fast since you just hit reset and it takes you to the beginning. You have to close the game and restart the programme on PC which is much slower. You hit reset on PS2 but you have to sit through the PS2 boot up screen which takes a really long time and you hit off and then the on button on XBOX. Overall from what I've gathered, PC has the fastest loads but you can reset the game much faster on GC even though saving is instant on PC. I'm no expert of course but this is what I've gathered with my very limited knowledge of this game.
