LS30 Joystick Games

I'm planning on eventually buying Time Soldiers and Ikari Warriors PCBs but its pretty hard to locate LS30 joysticks at times.

I have seen both board pinouts and neither have anything that indicates the LS30s are attached via the jamma edge so I believe they are hooked up via a connector on the side of the board.

Is there a way to replicate these joysticks? Or does someone know the pinout for that specific connector which is probably analog?

i know its not the original, but happ makes a rotary joystick (even says for ikari warriors)

Incase you didn't know, use the non-optical(kind of duh) rotary if you want to get the happ part.
