guitar hero 3 Wii

[u_say_go]

does anyone know how to enter cheat codes for Guitar Hero 3, Nintendo Wii? I went to a few different websites and found codes, entered them as told, but none of them work for me.
Looking for the code to unlock all songs.

Their codes always work for me. If not, I'm no help to you. ;)
