Hey, So I'm playing Guitar Hero: World Tour with my friends. I know it's famous for NOT having a "no fail mode" like Rock Band 2 has. My question is: can I hack it in Ocarina? Or whatever other HBC app? I've seen some *single player* cheats, one of them keeps your rock power bar full (basically meaning "no fail". But does it work in multiplayer mode? If not, does anybody know how to make Guitar Hero not fail when playing with 4 players? Thanks!
