Forgive me if my forum etiquette is bad.
Im new here and Im just starting getting into MODs. Im planning a Rasberry Pi portable game and I was trying to figure out how I was going to get buttons from a controller and wire them.
My question is: Is there a certain place where I should cut the PCB of whatever controller I use to wire it to the GPIO of the Pi? Which controller's with ABXY buttons, excluding the SNES, are easier to wire? Some controllers have alot of components on the back.
Can someone help? So i wont spend so much on controllers because of botched PCB boards
