Instructions
Clear space around your Nintendo Wii to make sure there's enough room above or around the console to accommodate the controller. You should also consider moving the console closer to where you'll be sitting or standing to account for the Gamecube controller's wire.
Open or remove the hinged panel found on the side of the console adjacent to the "Power" button. If the console is positioned vertically, this hinged compartment is at the top of the console. This compartment contains all the inputs required for any Gamecube peripherals.
Plug the Gamecube controller into the port closest to the front of the console (the side with the disc slot.) This port is for the first player, with the second, third and fourth player slots following respectively.
