Many years ago, Nintendo released Super Mario All-Stars for the Super Nintendo.  The SNES, having a new controller layout, required a new control setup to play the classic NES games.  Instead of making B the run button and A the jump button, they chose, quite wisely, to make Y the run button and B the jump button, the same way that Super Mario World was controlled.  This is much more natural, since you can easily hold Y with the tip of your thumb and press B with the pad of your thumb, whereas to do the same with B and A would require rotating to an awkward position.

My question is: WHY OH WHY has Nintendo completely forsaken this much-preferred control scheme for playing NES games, and even N64 games, using a classic controller?  I first noticed this in Gradius, where it wasn't too much of a problem, since you only rarely press A to powerup.  I played Kid Icarus with a sideways Wii Remote, so that didn't bother me either.  Mario 64, however, gave me huge problems on the classic, enough that I had to switch to the Gamecube controller because I was constantly confusing punching for jumping.  What the hell were you thinking, Nintendo, you got it right the first several hundred times, why screw this up so badly?

I like play all NES games with the wiimote. But then again I never played NES games on the SNES or anything else except the NES. I did buy two classic controllers because playing Super Mario World on the Gamecube controller was difficult.

Yeah, I don't like playing NES games with my Classic Controller, I much prefer just turning the remote on its side. It actually took me a few tries to release I wasn't going crazy while playing Zelda with the Classic Controller and the controls really were screwed up.

Is it still the same if you use your old SNES controller?

More like an update to the games, I think. Each game brings it's own emulator and seems to be no different to the Wii from any other channel.
