All I can think of doing would be to follow each trace for each button on the controller board and then wire up to a controller port. Turbokon and thesteve do this regularly but I have yet to see write up from either one of them.

Hey, I wanted to post an update for this topic. I hadn't done the external controller port for a while and did one yesterday. There doesn't appear to be any documentation mentioning the need for the 4 Diodes that should be installed on the internal controller board. This helps greatly with controller compatibility. Without the diodes, only certain controllers will work. Picture of where the traces need to be cut(or pins lifted) then have a diode placed in between. I didn't have any smd diodes on hand at the time so I ran wires to the back side of the controller board to 4 diodes and then back to the front again. Marked with Blue  |
