Ok, i recently got a Wii U and had no problems getting the homebrew channel running on the virtual Wii. I then researched ways to get GameCube games running because at the very least i HAVE to have Luigi's Mansion. I first tried Nintendont over Devolution because of the anti-piracy bullshit however with Nintendont only some GameCube games worked (LM was one) but most didn't and you could only use wired controllers. Part of the reason for choosing Nintendont was because i didn't have a retail version of LM but i managed to get one now and following some youtube vids have managed to get it working on my Wii U via sd card perfectly and i also bought one of those MayFlash GC Gamecube Controller Converter Adapters so i could use my all time favourite controller (my Wavebird) however one thing that is annoying the fuck out of me is that when i go to play it the right bumper button is like it's permanently stuck. I can't get the vacuum Luigi has to stop and so therefore can't play the game properly. Surely someone must know a fix to this.
