This is a PC Clone of the PS2 game, Guitar Hero. It works with the SG controller with the help of a PS2 to USB adapter. The project is still in development and recently I have released a 2D version with all of the basic functionality.
The game is dependent upon Anton Struyk?s Freetar Hero Editor. The editor can be used to create an SNG file for any MP3. The SNG file contains the note level data for the song. Using both of these files, PC Guitar Hero can be used to play the song.
