This is a fully functioning Guitar Hero III game including the No CD crack so you don't have to use software to pretend like you have a CD in the drive. Secondly this has been edited by me so that it is fully compatible with Windows XP/Vista x64 bit. Every other download of this game is NOT compatible with x64bit operating systems so unless you know how to edit the program files....just download mine and make it easy on yourself.
Double click Guitar Hero III (windows installer package)..........follow onscreen instructions.
open GGuitar Hero Crack - No CD and copy/replace the Guitar Hero .EXE file in your default saved program location.
That's all there is to it!!! It couldn't be easier.
