Overview
The XenoGC is a drivechip for the Nintendo Gamecube. It's installed directly on the disc board and injects patch code into the DVD drive at run time to enable debug commands and read DVD+/-R/RW. The original project name of the modchip was Qoob Lite (later discovered from the source code).
Versions
There are two versions available of the XenoGC. Version 1.0 has no MultiGame disc support via the XenoShell, but version 2.0 does. Version 2.0 is actually internally version 1.5 in the source code. The 1.0 XenoGC also had a Green LED to indicate when the drive was successfully patched whereas the 2.0 has an orange LED (As do the clones).

Settings
- General Info
You can adjust a few settings by holding various buttons on controller 1 while booting a game - this means from just before and during the black screen as the boot up menu goes away and the game starts up. The settings will be in effect per boot and not change behaviour permanently.
- [L button] Disable audiofix
If you modified your backup images to work with bioses that didn't support streaming audio correctly, you can disable the native fix.
- [R button] Disable DREfix
Turns off the native read adjustment/retries. Can be useful if you want to scan a disc for read errors. The chip will not try to prevent any errors and use the default read settings
- [X/Y button] Force NTSC/PAL display mode
Will force the selected region's display mode regardless of the actual game region. This will work for some games, for others it won't.
- [START button] Version display
On a version 1.0 XenoGC it shows some basic version info (Chip, GC and drive) On a version 2.0 XenoGC it shows the XenoShell which only runs in PAL50 (bug?) and is only useful for running MultiGame discs (not multi-disc games).
- Status LEDs
The XenoGC features two status LEDs to indicate correct function. The red LED is active when the drive resets and the chip is doing its job. Once the drive has been patched successfully, the green (or orange on XenoGC2.0 and clones) LED will light up. Check your install if you only get the red LED, or it doesn't light up at all.
