Damn, TubeHax was the easiest for me to setup without having to clear my fucking browser cache all the time... I don't have OoT or Cubic Ninja, and from what I hear, Smash Hax is a bitch to setup and use. I'm on a 2DS (O3DS without 4.5 support, I guess you could say), so my "hax" are limited.
I think you can setup ThemeHax, then.
