@helirob said in Can the mame menu be disabled in lr-mame2003-plus?:
it's frustrating because I have no idea how this happened
Hehe, i went through that frustration a long time ago, it actually led me to use FB instead of MAME, later becoming one of their devs.
Afaik, the situation with that MAME OSD menu is not as messy as it used to be though.
