[quote name='javeryh']I just read about some cheat that allows greater room for mistakes or something - anyone know anything about this? Apparently this is how some people are so good at the game...[/quote]
It's called hyper speed, I don't consider it a cheat. It makes the notes come faster, so just like you said there's more room for mistakes. I tried it once and I didn't like it too much. Put in this code at the main menu:
B, O, Y, O, B, O, Y, Y
The letters being the color of the fret.
