i was messing around with the tab/menu for mame, some how i put my R button on my controller as well as Tab that both were opening the tab/menu for mame. i pressed enter on the key for tab in the mame menu and hit escape twice to clear it like i have done with other mappings.
now i have locked myself out of the mame menu as tab wont' even bring it up? is there a cfg file somewhere for mame that i can ssh in and fix to get this working again?
