kudos for making this, and it seems to work beautifully, but honestly i don't see why everyone thinks it's the end of the world to have to use the 3ds controls. let's be real, competitively, i'm pretty sure almost every tournament will be utilizing the wii u version of sm4sh. i mean we're only going to have to wait a couple months at the most for the console version of the game, so no one really has to 'adapt' to the 3ds, you kind of just have to play on it for a little while and learn the engine and figure some stuff out, then go right back to your perfect gamecube controller when winter hits and you have the version of the game we actually all want.
AND apparently a lot of pros who have played the 3ds version like the way it feels MORE than the wii u version, and when i got to play it at smash fest it felt great. (keep in mind the demos/tournaments were all using early builds though). so just enjoy the 3ds version and take it with you LITERALLY EVERYWHERE and then enjoy your wii u version + gamecube controller. win/win.
