I've thought that for awhile too. Why would you really need to do a full audit with a UI anyway. You can't repair anything and instead of a full audit you can either do an individual set audit or easier yet, just hit enter & see what it says is missing or loads properly. Unless the full & indy audits are so intertwined that it wouldn't work. But then MAME wouldn't work at all. It still has to know & try to load the correct roms.

Pessimist: Oh, this can't get any worse!
Optimist: Yes, it can!
