Many Super Smash Bros. fans grew up playing Super Smash Bros. Melee for the Nintendo GameCube system， and some will always prefer that system's controller. The Nintendo GameCube controller also could be used in Super Smash Bros. Brawl for Wii. To honor that devoted loyalty to a classic way to play， this adapter allows up to four original Nintendo GameCube or WaveBird controllers to work with Wii U.
