I am running Mame 1.28, Mala for frontend and have the Ultimarc aimtrak module in my gun. On some games, like Egg Venture, everything works perfect, but other games like Vs Duck Hunt every trigger pull shoots twice and on all the Exidy games it is stuck on rapid fire. It has this same behavior in MameUI. I have tried different settings but can not figure out why this is happening. Anyone know what to do? Thanks.
