Japanese PS2 is faster than Xbox, im sure, as the slower skips for xbox, and the level changes and the boss changes make JP PS2 the 2nd faster version, because it easily competes with the Gamecube Version, imo I feel Xbox should be third on this list and JP 2nd

Did you totally disregard the boss changes?

Fast load times doesn't = Faster Version, you have to take ¤everything¤ into account
