Guitar Hero III: Legends of Rock Cheats

[Jeremy]

Go to “options” and then go to “cheats.” Now, cheats are entered completely differently in the third installment. You now have to strum with the frets on just like normal playing! Two or more notes in parentheses indicate a chord.
G=Green, R=Red, Y=Yellow, B=Blue, O=Orange
