Do Wii Controllers Work on GameCube? No Cross-Compatibility

No Cross-Compatibility

Wii Remotes (Wiimotes) do not work on Nintendo GameCube.

Technical Reasons

• Different Ports: GameCube uses proprietary 4-pin controller ports; Wii Remotes connect via Bluetooth (wireless) or Wii's external extension port (wired accessories).
• Different Protocols: GameCube controllers use a serial polling protocol; Wii Remotes use Bluetooth HID with proprietary extensions.
• Power: GameCube ports supply 3.3V for rumble; Wii Remotes run on AA batteries.

What Works on GameCube

• Official GameCube Controllers (wired, WaveBird wireless).
• Wii Classic Controller / Pro Controller — only when plugged into a Wii Remote on a Wii console (Wii mode), not on GameCube hardware.

Playing GC Games on Wii

If you have a Wii (RVL-001 / RVL-101), you can use GameCube controllers and memory cards in the top ports to play GC discs natively.
