The XenoGC is a drivechip for the Nintendo Gamecube. It is installed directly to the optical drive's logic board and injects patch code into the drive at run time. This enables the execution of debug commands and reading of DVD+/-R/RW media. The original project name of the modchip was Qoob Lite (subsequently discovered in the source code).
When Installing one of these bad boys in your Gamecube, you will likely need to Tweak the Potentiometer of the Laser in order to get Burned media to read properly.
I have a full install video here (Wire Method)
Chip comes with a free ModzvilleUSA seal of approval sticker!
