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, Nintendo is introducing an adapter that lets up to four original Nintendo GameCube or WaveBird controllers work with Wii U.
