Greetings. Ive seen some info on this forum regarding this but haven't had much luck making it work so here goes. I'm using WIN8 with MAMEUI64 .149 So I bought an EMS TOPGUN3 and I've got the drivers and the calibration down or so it seems. The "TOPGUN Panel" registers my clicks on the gun. In windows I'm able to control my mouse pointer with the gun and click on things with the trigger. Loading up MAME Im able to aim the gun and highlight items in the TAB menu but the trigger doesn't seem to "click" anything. However, the crosshair in game only moves with my mouse. Attempts to get the "lightgun X analog" in the TAB menu to register the horizontal movement as per the instructions don't seem to work.
