Rocking a mayflash Universal Stick ATM (which is crap, I know. Still works good enough) and I think I might just get a PS2 to wiimote adapter for it and then do that. --- EARTHBOUND FANS, GO HERE :D Luminehall.net
I would assume you could since the system is supposed to be compatible with most wii accessories.
I'm also hoping this since I sold my PS3 since I didn't play it and had a T.E. stick left over for it that I gutted and swapped in the PCB from a Cheap Wii stick I bought from Japan and works great with tatsunoko vs capcom. I really don't want to have to buy 1 of those new Wii U fight sticks until they get more fighters.
