I am running mame on windows 7 pro 64 bit and 64 bit mame .172 from Launchbox/bigbox. I am using an ipac with a trackball. The trackball goes to the ipac and into the serial port. None of the trackball games are working, but the mouse works fine in windows. I changed mouse from 0 to 1 and trackball_device to mouse in mame.ini. Any idea how to get it working?
1) Can you use the trackball to select stuff in Launchbox/bigbox? 2) Does your regular mouse work with trackball games?
I see you know your way around the mame filesystem (editing the .ini file). Sometimes UI frontends dont play nice with the mame.ini. In GameEx (an older version mind you) you had another config to deal with.
Have you tried the games using only mame, as in launching it straight from the exe?
