I know I can use a GameCube disc on a wii but to play them do I need to use a GameCube controller or I can use a Wii
According to Nintendo Support, you cannot play GameCube games with a Wii Remote.
Please note that the Wii Remote cannot be used to play GameCube games, and that standard GameCube controllers or the wireless WaveBird variant are required.
This also means that your Wii must have GameCube controller ports in order to play GameCube games:
Despite that, Nintendo Support recommends checking the Wii's Model No. to determine if it's compatible with GameCube games:
- If the Model No. starts with RVL, the Wii system IS compatible with Nintendo GameCube software and accessories.
- If the Model No. starts with RVK, the Wii system IS NOT compatible with Nintendo GameCube software and accessories.
