It works on Wii U games and ONLY Wii U games. Gamecube games are run under vWii with Nintendont.
To use a Gamecube Controller with Nintendont, plug in the adapter and the controller.
You'll need a Wiimote to launch the game without it setting the Wii U Gamepad to Player 1.
Using the latest nightly and a dualshock3 i just get a black screen and have to pull the plug on my WiiU to recover. I also tried a wired Hori PS3 controller (HoriPad3 Turbo Plus) and it isn't detected by either the stable version or nightly. Any ideas? :'(
Does one need to be in CFW for it to work? Or is just launching it with haxchi and HBL enough? I decided against cold boot. Currently my config just boots to HBL and i have to hold b to get into CFW.
Also, does this work with the PDP Faceoff? I kinda wana buy one.
