So I'm playing some of these old school Virtual Console games, and the D-Pad on the pro controller is very picky with diagonals. In Mega Man X, I won't move forward sometimes if I'm holding down/forward. X will just stand in place. Same deal in Super Mario World. Is the Wii U Pro controller that picky with it's directions or is it just me?

Not sure, but I haven't noticed any problems. It might be that X wasn't meant to move when holding down/forward. Have you tried using the gamepad for comparison? i'm pretty sure it's the way the game is meant to be.
