I just wanted to say something about the control situation, and brought pictures.
This is the standard way that an NES controller was supposed to be held. (Thumb positions roughly drawn in bright green with MSPaint.) You're supposed to rock your thumb left or right to press a button.
But if you held the controller like
this, then any light twitch of your thumb-tip would trigger the "B" button, and depressing you thumb would trigger the "A" button. This was extremely useful for lightning-quick fire control in a game like Megaman, and let you easily fire while jumping at the same time (instead of the "one or the other" effect you get by rocking your thumb back and forth). The odd-looking position of your right hand is really not bad, if you let the controller turn slightly clockwise (but you can't look at it while playing, or you'll get distracted).
Since the classic square-brick NES controller, Nintendo has been trying to make it more comfortable to use the "standard" position, by giving the buttons a small turn counter-clockwise, which makes it even harder to use the "twitch" position.
The SNES controller has that slant, but by adding a second row of buttons, Nintendo invented a perfect "twitch gaming" setup, where you could use the
"B" and "Y" buttons, like you used to use the
"A and "B".
The GameCube controller abandoned the SNES style (well actually, the N64 did it first, but the GameCube did it too), but with some minor old-school effort, you can still play the
"twitch gamer" way.
But of course, Capcom messed that up by changing the buttons layout for no good reason. It's still possible of course, but you'd have to play like
this, which would probably break your wrists.
Capcom's swap of the "A" and "B" buttons messes with people who played the "standard" way to a lesser degree, by just making things feel backwards.
Since Sony's controller is an evolution of the SNES controller, the PSone (and likely PS2) versions of the games use the "perfect twitch gaming" setup of using the "B" and "Y" buttons that the SNES invented (although Sony invented stupid new button names for them, which will probably overtake the SNES names, in terms of popularity, sometime soon).
Does everyone get that? Was it clear enough?
