yep I had already been too that gem of a website and that was one of the many different configurations I have tried. the version of mame would not allow me to choose the trigger for the light gun as button one. after choosing a diffent key for button one I tried to choose the x plane in the setup menu but mame did recognize the gun all I could see happening on the screen was a shaded selection bar separate from the one I was using on the menu moving up and down with where I was pointing the gun on the screen so I know the gun was working in windows but invisible to mame as a gun
