Many Super Smash Bros. fans grew up playing Super Smash Bros. Melee for the Nintendo GameCube system, and some will always prefer that systems 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.
