Via their official Twitter, Nintendo of America has revealed that will be releasing a GameCube controller adapter that will allow Super Smash Bros. gamers to play the game with what may be their controller of choice. The adapter features 4 GCN controller ports for authentic local 4-player SSB action.
There's no word or price or availability as of yet, but we're guessing that it'll be a must have accessory for any serious Super Smash Bros. fan.
