The Xbox 360 version of Guitar Hero III: Legends of Rock has cheats codes that will improve your score and accuracy, but you'll have to earn five stars on every song without cheating if you want to unlock all achievements.
These cheats are for the Xbox 360 version. There are also cheats for Guitar Hero III on Wii as well as the PlayStation 2 and PS3 versions.
How to Enter Cheats in Guitar Hero III for Xbox 360
Instead of using the Xbox 360 controller to enter cheats, input codes using the guitar-shaped controller that comes with the game. Select Options from the main menu, then select Cheats > Enter New Cheat. Once a cheat is unlocked, toggle it on and off from the Cheats menu by pressing the Green button.Maritsa Patrinos / Ach5
