Hey, I hope this works for you because I spent forever trying to find a way to patch GH3 to 1.31
so I decided to make my first torrent because I didn't want this game to die with the rest of the
download links I found online.

So, here are the steps to installing:

1. Mount GHIII.mdf in GH3 PC Image
2. Run Guitar Hero III Installer.exe in that mounted drive
3. When that installs, run GH3_PC_1.3_Patch.exe in Patches, DO NOT RUN GH3_1.31_Patch FIRST! THIS IS IMPORTANT.
4. Then, once patch 1.3 is installed, run GH3_PC_1.31_Patch.exe
5. Finally, copy gh3.exe from Crack into Program Files (x86)/Aspyr/Guitar Hero III and replace the one in there

You're now free to play the game and install custom content! I've packaged a chart creation tool and the
Guitar Hero 3 Control Panel program with this (in the extras folder) so you're ready to start making you 
own songs right away.

Rock on!
