I traced all this stuff out to make up some full blown Southpaw controllers (swap D-pad for A,B,X,Y) for a couple of really kool guys, and one jerkass.
If you want to add a button, swap a button or need to repair a trace that got ripped up and a button doesn't work this outta help ya out a good bit.
The reason that the Guide button and Start button aren't traced out is because they have squat to do with the other buttons. They are the only 2 that actually have a "common ground" and are the only 2 buttons on it. All of these traced out here are "entangled" together, like a keypad or keyboard. Sometimes swapping just 2 buttons means you may be dealing with 4 or 5 because of the way they're all laid out in there.
