I have the happs 3" trackball installed via ps/2 optiwiz, I have a ps/2 to usb adapter, the frontend recognizes the TB but not the actual games, I have read and searched and tried some of the advice given but nothing worked. I have the mouse set to 1 and for trackball_device I tried these options:
-trackball
mouse 1
mouse2
any help would be great, thanks I should mention that I have a usb mouse plugged in that is used in windows.
here is my current mame.ini for input devices
