check out my posts on something like this... Here is an excerpt from HS forums..
"So I have been having this problem with the Aimtrack guns the Drakin made me for a little while now. They worked flawlessly in the beginning, then I got the panel Jack made me and everything was awesome. I got a new computer HP Athalon Quad Core Win 7 6 Gigs Ram, etc… Everything was great. Then the guns started acting crazy. When we would pause a game, they would come back out of whack after the pause, then had to recalibrate. Then a couple days later, they stopped working. The software wouldn’t even start up, it crashed when calibrating. I could not reassign the gun ids and when I plugged the guns in, my panel stopped working… Unplug them and DELETE THE default.cfg and the panel was back. But plug the guns back in and ALL the buttons were off… Player 1 Start was player 2 Coin and etc… Weird right.
So maybe my usb ports are bad or the guns were bad, so I plugged them into my computer at work and calibrated and they work fine… NOT THE GUNS.
I unplugged my panel at home for the first time and plugged the guns in.. deleted the default.cfg
Now with the CP unplugged, he Ultimarc software comes up IMMEDIATELY, configs and calibrates perfect. I set the gun ids to 3 and 4 upgraded firmware, etc.
Played 15 guns games, configged them all… they work perfect… BOTH GUNS… Wahoooo… Plugged the CP back in, rebooted and everything works great…
Not sure why I didn’t try that in the beginning, but I am not sure why it would matter, but that could be me cause I am a novice at some of the setting and frankly a newbie at this whole thing.
Time Crisis even works on my new computer with hardly any speech lag, but for some reason the cursor on the screen is about 5 inches off of where the SHOT actually goes… not the guns, but I think this may just be the rom… anyway just thought I would introduce everyone here to the problem… lol… and it seems to be fixed for now…"
It was some sort of an issue with my CP plugged in first... I could set the trigger fine, then in Mame... nothing... try unplugging everything except the guns and try it again... Hope this Helps
