desperately need guitar hero cheat please

[Dylonius Funk]

I know i should put this in the Guitar Hero thread but i figured this way there's a chance someone would read it. I have a friend over right now and he just got Guitar Hero 2 and we want to do some multiplayer. Problem is i can't find an unlock all cheat for GH2. If anyone knows of one i would appreciate it greatly. Thanks

According to GameFAQs (http://www.gamefaqs.com/console/ps2/code/932565.html), there is no "unlock all" cheat (assuming I didn't miss anything).

Take turns playing through normal or higher difficulty and unlock all of the songs that way.
