All Virtual Console games have their buttons mapped to the respective buttons on the controllers, however, in certain circumstances users can use X and Y instead of A and B, if the original controller does not have X and Y buttons (for example the NES). In certain titles, such as Nintendo 64 games, there may be specific controls tailored to the Classic Controller or GameCube Controller. Nintendo 64 titles that originally provided force feedback via the Nintendo 64 controller's Rumble Pak peripheral however, are not supported by the built-in "Rumble" feature of the GameCube controller.
