Why won't rock band load on your PS2?

Answer 1

Apparently in the rush to get the ps2 version out the discs had some problems and some ps2 units usually the fat ones but not always, won't load. I found it out the hard way and bought a new slim ps2 today. Now it works (the same copy of the game that wouldn't load on the fat ps2).

Answer 2

some ps2s just can't load it unless your disk is just scratched try it in another ps2 if it doesn't work ther its your disk if it does its your system hope this helps!
