I've been looking desperately for someone to help me with this, but there seems to be no forum that i can find that can help me with the answers.. if you know of one please send me a link.... (ice also tried going to arcade rooms to fget incontact with an arcade machine mechanic...but no luck) .. i have an original factory made carnevil arcade machine, it's NOT a mame project...i dont know much about it, but it seems to have a very minor issue...maybe some of you know what it is and its just a minor fix, during game play, whenever i pull the triger, it just reloads, the trigger and pump works fine...i thought the guns just simply need to be recaliberated, but whenever i aim it doesnt seem like the signal from the optical lens is reading to the screen, isometimes...maybe one out of every 100 trigger pullls it will register a shot on screen at exactly where im aiming....can it be a bad connection?...do i need new guns? any help or directory in help would be appreciated, thanks
