I would have said something had I known of this forums existence at the time.
Seconded. I always got MESS along with MAME because I had a machine which I used to emulate just console games, and I found it more convenient to use the same software list set I had instead of keeping multiple around. MAMEUI takes up way more space because it has all those extra arcade games, which I don't need. I beg of you, please continue it!
