The DuoQ was a drivechip for the Nintendo GameCube, and was developed by Team Omega under their 'Duo' brand name. It is powered by a Parallax SX28AC microcontroller and has identical functionality to the XenoGC v1.0 (perhaps a clone under a new name), except it cannot be reprogrammed with new firmware.

Features

  • LED indicators for troubleshooting.
  • Low-power consumption design.
  • 6-wire installation.
  • Support for multi-disc/multi-game and Action Replay/GameShark discs.
  • Compatible with GameCube originals, backups and imports.
  • Jumper-less solution for both PAL, USA and Japanese machines.
