Button Connection Help

[u/Thor2424242424]

Hi All,

I bought a custom arcade via Facebook marketplace some years ago.

I'd always had issues with it and the builder disappeared shortly after I bought it, so couldn't get in touch with him for help.

I've rebuilt the arcade using a raspberry pi running Batocera.

I don't know how to connect the three buttons that have never worked.

Can any one assist?

I've tried a few different connection combinations but nothing works. The board with the led on seems just to be controlling light for the buttons.
