Only thing to watch out for the x360 padhacking is that they pretty much all require multiple grounds - can’t daisy chain it all like a PS2 pad. That, and the solder points for the d-pad on the official microsoft controller are a bitch.
basically you have your controller pcbs in a box instead of inside the joystick and you use a method to connect the box to your joystick (most use db-15 connectors) and you have dedicated system controls instead of converters
Oops. Yeah I found this thread through search. And I also found that live dedicated one through search as well. Problem is I found this one first, and already posted, before I found the current one. >.<
