Ok, some background. So my cab is almost completed, and I just picked up a coin door. I figured it would be as easy as running an i-pac to get the microswitches working. I got everything all wired up, and assumed I had to set the controls for the i-pac in the Retropie menu. I just had to hold the coin door switch and Retropie would recognize it, so I jumped the connectors on the i-pac with a wire to set the controls, and set the Select command on the coin switch. I figured this would do it, but when I get into a game it won't recognize it as a coin entry. Even if I unplug all other controllers from the RPi it still won't show a coin entered.
I'm flustered by this as the Retropie menu will acknowledge the coin switch, but not in-game. Any ideas what I may be doing wrong?
