I have 2 happ guns connected to USB2GUN and have a JPAC hooked up to my Maximum Force cabinet with MAME. I have all of it setup and everthing.

I am having issues with the gun calibration. Like the calibration goes well and in the little preview window it looks like the gun is aiming correctly.

However when I am playing Lethal Enforcers, it seems like the further away from the center of the screen I get, the more offset my shots are. When I'm trying to aim at guys off center, like say about 1/2 way between the center and left edge of the screen, the bullet holes are showing to the left of where I am aiming.

I have noticed that this doesn't seem to be the case with the vertical positioning though. If I shoot towards the top of the screen at the center horizontally, it appears to be working fine and seems pretty accurate.

I am guessing this has to do with the screen being 4:3 yet the analog controller it THINKS the gun is, would be 4:4 or 3:3?

The odd part is I had this all setup in my other MAME cabinet as a proof of concept, and the accuracy was perfect. When I first was getting this new project setup I had another monitor in it and the tracking was even worse, so I swapped them, and now in my Maximum Force cabinet I have the exact monitor that I was using with my proof of concept that was working perfectly.

Is there some trick that I am forgetting to do with the calibration of the gun that I don't remember from doing it in my other cabinet? To be fair it was over a year ago. I'm also wondering if there are maybe some settings I need to set in MAME possibly?

Any help is appreciated, thanks.
