Does anyone know if there's a side-USB port on the GameCube Controller Adapter? I just realized that my Wii U's out of space on the hard drive, and my plan was to just download Smash U and a few other games to an SD Card, but apparently if I want to make room for Smash I need to blow $70 on a hard drive because there's no SD Card support on the system, and the hard drive goes in one of the two USB ports that the adapter needs to be in simultaneously, meaning I either can't use the GCN controllers or I can't play Smash if I go digital like I'd hoped.
Incidentally, can anyone direct me to an External USB Storage Device that doesn't break the bank? I finally gave up and went to get my free Club Nintendo copy of Game & Wario, but now I can't get that either because of this hard drive nonsense; I honestly thought SD cards were good enough, and it works wonders on the 3DS, but apparently, the affordable option's not available on the Wii U.
