ok so update, after removing the CoinOps settings, and only using the FE settings, it will run without freezing, and still uses MAME button mapping when game starts. The issue I'm seeing now, is when CoinOps switches games during attract mode, the buttons turn off. If I manually change the game using the joystick the button animation starts up again. The other settings appear to not work in trial mode so not sure if that is something I need the full version to have working? Don't mind buying the software just want to make sure it works completely.
