Downloaded games on the Wii?
Does anyone know if I have to use the classic controller for the games I downloaded the Wii th or if I can use my controller GameCube?
You can use both, but only one or two games do not work with the GameCube controller. Get a classic controller because they are easy to find in stores today.
