AutoMap is good for a start, but it would be nice to be able to customize them. I've got a USB controller and I would like to be able to set its D-pad to the NES D-pad, and my start, select, A, B, etc.
Currently my equivalent Start and Select rotate the field through the horizontal axis. I can't un-bind default buttons from A and B, and I can't actually deactivate Input buttons on the 3DNes config screen.
3D is great but I'd like to also play these games comfortably.
