Looking for help - wiring a hacked PS1 controller

Chippermonky was kind enough to send me a hacked PS1 controller and I’m only now realizing that I have no idea what to do with it.

I’ve been searching the forums for a detailed explanation but am coming up short. If anyone has a link or is willing to msn me through please send me a PM.


Solder the wires to the corresponding microswitches.
