minimal GameCube IPL.
Flash the latest build to your Qoob Pro or Viper as a BIOS.
The Qoob SX is currently not supported because it uses a very different process to boot, and reverse-engineering efforts so far have been unsuccessful.
After flashing, place an ipl.dol file on your SD card and turn the Cube on, it will load it right away. The IPL also acts as a server for emu_kidid's usb-load, should you want to use it for development purposes.
