I got a question. For thoseof YIU who play video games, will the new gamecube adapter work for any gamecube games you wamt to play on the Wii U? I want a gamecube game but I only have a Wii U and they only work on GameCube and Wii. The gamecube adapter makes it towjere you can play gamecube games on Wii U but will it work with every game?
