You can get into that secret world?!!?!?!??!?!?!?!?!??!?
I've tried for hours, days even, and I can't get it to happen. This trick is 10000000000000000000000000000000000000 times harder than that easy ass 22% with boost without space jump.
Um, I guess some people just turn on their gamecube before the TV, and thus they never see the gamecube logo that appears while the cube reads the disc. Thus, you can witness this "difficult" trick by breaking your (read: not mine :D ) usual sequence and turning on the TV first. :D
