I have my Trackball buttons 1, 2 and 3 as Mouse buttons. I set them up in MAME so that they are the same as P1B1, B2, B3. When I play a game, say Missle Command, I push Mouse Button 1 by the Trackball and Mousebutton 3 Fires at the same time. What am I missing?
Thanks in advance, I'll get this stuff figured out sooner or later =p
