The GameCube controller adapter for the Wii U will not be compatible with any software other than the upcoming Super Smash Bros game, Nintendo has said.

Nintendo clarified the peripheral’s lack of compatibility after it had mistakenly suggested it would work with other Wii U games that support the Pro Controller.

“The GameCube Controller Adapter for Wii U is compatible with Wii U and Super Smash Bros. for Wii U specifically – it is not compatible with any other Wii U software,” Nintendo said in a statement issued to GameSpot.

“The adapter is also not compatible with Wii and we apologise for any confusion”

The GameCube controller adapter will ship alongside Super Smash Bros for Wii U when the game is released on November 21 in the US and December 5 in the UK. It allows players to connect up to four GameCube or WaveBird controllers to the console.

In certain territories, such as the UK, the adapter can be bought as part of a Smash Bros bundle, or separately at £17.99. Nintendo is also issuing a limited run of GameCube controllers for the adapter too.
