I am considering practicing ILs and potentially full game runs in the future, which means I'd like to submit them if I get any good runs.

I recently acquired a Wii U as GameCube is tough to come by, and is an overall more interesting system to use than the Wii given that I don't care much about motion controlled games.

I noticed that in some threads here, it is mentioned that Nintendont is banned (it is the only way of playing GameCube on a Wii U...), but the rules only seem to forbid it for runs faster than a threshold time. No mercy for ILs though.

While I could also acquire a Wii or GameCube alongside the game disc to qualify, do I need to use any specific controller? I am considering getting a third-party GameCube controller, is it fine if it has turbo if I don't use it?
