The Gamecube controller was a horrible, poorly made controller. There is no need for an adapter for this horrible controller, or any controller return.

Its buttons, d-pad and overall design was terrible. This only caters to the fraction of Nintendo gamers that play Smash Bros Melee, who only like it to pretend to be cool.

They know its horrible but they do it to fit in with the internet messageboard types.

Its time for Gamecube fanboys to move on, and play on the factually better Pro controller, and Wii Remote.

Those were made to make Smash Bros an easy experience, and these competitive Nintendo Smash Bros fanboys only do this to fit in with Nintendo Fanboy Melee Trolls. 

These people don't even like the Real Smash Bros, and will go back to playing Melee soon enough, and the majority are not going to buy these new Gamecube controller/ adapters anyway.

Please cater to your Real Fans and Real Gamers that Play the Real Smash Bros, and not these fake Nintendo Fanboys that are Against change, and Only play the vanilla, nerfed "no items, final destination" type of stuff.

These Nintendo Melee fanboy Competitives are against change, and they are clearly against choice.

Thats why they only play this very limiting style of gameplay while the majority of people that buy the game, will try all different kinds of Real Items matches.

Cancel the Adapter.
