Cheat code to unlock all songs in Guitar Hero World Tour
If you’re like me, you just brought home guitar hero 4, and want to play the songs listed on the box. Unfortunately, it comes with only half of the (or so) available to play. I found this elsewhere, although its not too obvious that this is the code you’re looking for on other sites.
To unlock all songs:
Blue, Blue, Red, Green, Green, Blue, Blue, Yellow.
This was tested on my Wii, and should work on all other consoles as well. You get here by going to Options->Cheats->Enter new code. Once you enter it, you have to find it in the list, and turn it “on”. I.e., if you just enter the code, the cheat is by default off.
