I did something stupid while configuring my MAME controls.
Somehow I managed to set the UI Select" key to "none" so I can no longer toggle anything to change it back to the default of the enter key.
Can this be fixed without reinstalling MAME? I had a look in the config file and could see listings for some of the UI keys but not select.
I have another PC here with MAME running fine can I copy over a single file to get me out of trouble?
