That's one of the things I'm worried about regarding the VC N64 games. The VC controller has 6 buttons and two analog sticks; the N64 controller had 9 buttons (Land R, the C buttons, A, B, and Z) and one stick. Apparently that means mapping the C buttons to the right stick and the Z button to...I don't know. Of course, the games are optimized and whatnot, so I guess it'll work.
