I am terrible about knowing what names to call everything, so I will describe my problem. When I am in MAME, I hit TAB and a popup menu appears where I can modify input keys. For "SELECT" I mistakenly hit ESC - now I can't SELECT any game because it ESCAPES. I can't change it in that pop up menu, because I can't SELECT!
I made a mess of it, can I change back with a text editor? Which file contains those settings? Is it as easy as looking for an element named "SELECT = 'ESC'"?
Any help is appreciated.
