Someone please help. I got an Opti-pac, Happ trackball, I'm using Arcade OS and Mame. Everything is working fine, but I don't know how to set the games up for trackball use. Is it a setting within Arcade OS, or do I need to do something different when trying to change the inputs inside of Mame...Help
