With the Wii U gamepad and the pro controller on it wouldn't let me use them as separate multiplayer controls on the Street Fighter 2 VC game. This is because the Pro controller automatically takes the position of P1 meaning both controllers only control player 1.
I've worked out that if I set up a wiimote as P1 and the Pro Controller as P2 it will.
This seems like a bodge job rather than how it should work. Is this the only solution?
