I'm wiring up a control panel with the Fighting UGCI from Happ. I have 2 joysticks with 6 buttons each, a trackball and 3 mouse buttons. The only extra button slot I have I am using as an escape key. I still want a coin button which I can hook up to one of the coin drop slots on the UGCI, but I have no way of transferring that data into MAME. The only thing I find from searching (that would work perfectly) is
CoinDrop by Headkaze, but he is no longer supporting it.
Is there some other script/program that does the same thing, yet is still available?
