I know what you mean about not wanting to play Ocarina of time on the Wii, it does have a perfect setup on the N64. I think controller style doesn't matter as much with pre-n64 games though.
I still have my older systems, and a ton of games for them, and instead of dragging out the old systems to play them, I have an old laptop with s-video output and an N64/PSX controller to USB adapter and emulators for all my old systems and rom dumps of all my old games. With this I can play my old NES and SNES games on my TV just like the real things, only with an N64 controller. I find the N64 controller to be ideal for these older games since it have the classic style d-pad and the shoulder buttons and c-buttons which work perfectly for the SNES, and the a and b buttons that work perfectly for the NES. My preference would be to play my SNES games with a real SNES controller, so maybe someday I will lay down the twenty some bucks to buy a SNES to USB adapter. I just wish I could use the zapper.
Ah, and my laptop also works to play my old PSX games (only have a few games, and my PSX takes hours to load anything) and since my adapter has a PSX controller slot I can play them with the authentic controller, PSX games don't always emulate perfectly though and can take a lot of messing around with settings to get them right.
How great would it be if they made an adapter for the Wii so that you could use your old N64 controller to play your N64 games. Just thought of something else I am curious about, in Ocarina of Time, the top right corner of the screen had representations of all four c buttons and the a and b buttons with a label (i.e. jump, talk, Navi) or an icon representing the idem that is equipped to that particular button. Have they changed this on the Wii version to be representations of the classic controller's buttons rather than the N64 controller's buttons?
