Searched for so long now...

Trying to get a simple answer to this:

Have a wii U with homebrew.

Own a lot games and want to play them on diffferent emulators. (N64, SNES, Wii)

Wich gamecontrollers work? Or how can i get them to work?

-Gamecube controller? With Gamecube adapter? Is that any good?
-WiiU pro controller (not with display)
-PS3?

Does any wireless controller work?

I am very sad at the moment.... Nothing works....

There are TONS of videos out there to get the HOmebrew channel on the WiiU, but none about after you put it on...

Since the homebrew channel is running in Wii mode, you need a Wii remote (the one that points at the screen) and you can use a Wii Classic Controller (that plugs into the Wii remote.
