Things You'll Need
Instructions
Open the top access door of the Wii console. This reveals the GameCube controller ports. Four four ports are available here.
Line up the GameCube control cable with the Wii port. The controllers have one correct orientation that will allow them to be connected.
Press the controller firmly into the socket of the Wii. The first player socket is closest to the front of the Wii. Sockets for players 2 to 4 follow in order.
Power on the Wii and launch the desired game. Individual games may require the controller options to be changed in the game menu for the proper input.
