1 Player Start button only activates when released, not when pushed down.

When you hold down 1 Player Start button and push 1 player Button 1 or Button 2, it activates Coins for Player 1 or Player 2.

I reassigned the 1 Player Start button to another button and it also activates that action when released.

1 Player Start works normally on my other Jamma PCBs, so I know the input, wires and the button is working correctly.

I’m assuming there’s an issue with how the JAMMA pin is being called out by the JAMMASD.

I couldn’t find any downloadable software to fix the Jammasd.
