: The only way I can think without an extra analog input card is IF it's possible to have MAME mouse drivers accept a ps/2 mouse, two serial mice, and then maybe a way to interface a trackball to the gameport joystick hardware and have that recognized as an analog input.
: Otherwise I know there are other serial port cards that add more serial ports, I forget what they are called, it's an upgrade to the RS 232 that let's a cable be longer...it might be RS 422 or something like that, I'm not sure if those cards allow adding more simultaneous serial ports than the 2 that already exist, but if they do, maybe you can get 4 actual serial ports going instead of using the ps/2 and game port...and assuming MAME again can somehow have its mouse drivers access and accept the extra serial ports. That's just off the top of my head.
