hi there's no gamecube vc on wii u yet tho its confirmed & coming anytime now. how would you want it implemented tho. 1. same as nes, snes wii u virtual console games, where the game icon is on home screen, load it up & play the game on gamepad/tv. (gamepad, wiimote, classic controller, controller pro optional controllers) or 2. virtual gamecube, like the virtual wii but shows gamecube apps instead. this virtual gamecube also has memory management like the original gamecube(memory card screen) for gamecube saves. (optional controllers gamepad, controller pro, wiimote, classic controller & gamecube controller via what i said below) also a few cool ideals nintendo could do when gamecube vs is released. nintendo could release a usb dongle that allows 4 gamecube controllers to be plugged in for gamecube games, or games that devs with to support gamecube controllers in the future. (they can also do this with n64 controllers) also a gamecube memory card usb dongle optional save directory for gamecube wii u saves.
