not64 can be used, not with gamepad. i made a wii u usbloader gx install and posted it in the nintendont thread, if you are interested, you cant use gamepad in usbloader gx yet, but if you boot a nintendont game you can use your gamepad on that, no, wii games are not possible yet.Is Not64 possible yet? I'd like it more just for the N64 games that can't be injected (which is a lot, surprisingly... Conker, Banjo-Tooie, Mario 64 romhacks, Glover...).
Also interested in a possible USB Loader GX with gamepad support to just work with all Wii and GC games at once (assuming said Wii games accept classic controller), but that's probably not possible yet.
