Just got a lightgun for my gameex cab and installed with little trouble. The ems topgun 3 works pretty good except I'm having trouble getting anything other than the fire trigger to work in mame. Button one is the fire button in mame and setting that through the tab menu works fine but any other button pushed on the gun doesn't register. I would like to be able to add credits, start the game, and reload from the gun buttons. Anyone with any experience with the ems topgun? Please help!!
