How do you use a GameCube controller to play Wii games

Only certain games allow the use of a Nintendo Gamecube controller to play it.

To make sure that a game is compatible, please check the game's packaging or the game's manual, and read the section on "Supported Controllers".
You may also see an icon representing a Gamecube controller. This is a sign that the game may be compatible with it.

Instructions on which Gamecube button does what action in the game, should be explained inside of the game's manual.
