The Nintendo Wii edition of Guitar Hero III: Legends of Rock has cheats codes that make the game easier, harder, or just more fun to play. There are also secret characters and instruments that can only be unlocked by getting five stars on every song.
These cheats are for the Nintendo Wii version. There are also cheats for Guitar Hero III on Xbox 360 as well as the PlayStation 2 and PS3 versions.
How to Enter Cheats in Guitar Hero 3 for Wii
Instead of using the Wii remote, enter cheat codes using the guitar-shaped controller that comes packaged with the game. From the Options menu, select Cheats > Enter New Cheat, then strum the required notes. After you unlock a cheat, it can be toggled on and off from the Cheats menu by pressing the Green button.

These codes below refer to colored buttons on the guitar:
- B = Blue
- Y = Yellow
- G = Green
- R = Red

When entering codes, strum each note or chord as if playing it in a song. When two colors are listed together, such as BY for blue and yellow, both colors must be strummed at the same time.
