When I was sixteen years old I took one of these drawer-style cassette racks and drilled holes in the top to accommodate an arcade joystick and ten buttons.
I took apart a PlayStation controller, sanded off the solder mask, and soldered wires directly to the copper traces, running from the PlayStation pad to my arcade stick's microswitches. Then I went to a computer market and bought a PlayStation to parallel adaptor and plugged this abomination into my printer port because I was still waiting for someone to invent USB, then spent a merry afternoon figuring out how to get DOS to see it, then get MAME to see it, then I enjoyed me some Sunset Riders.
THAT
was an EASIER CONTROLLER SETUP
than FUCKING RETROARCH
Hahaha, the pictures are still online!
