Rocking Commodore 64 style
Guitar Hero is a game that has wasted countless hours shreading. People have hooked their controllers up to a PC, someone created a PC application that works of your keyboard like Guitar Hero called Frets on Fire, and now someone hooked the controller up to a Commodore 64.
Toni goes on to explain about debugging and attempting to get the two devices to interface with one another. Hopefully they'll post some source and a more complete tutorial on how this was completed so Commodores across the world can be booted up again.
