I'm almost glad that it doesn't work for you. seriously, I spent a good hour on it messing around (and I'd like to think that I'm not an idiot), so it's good to hear that it's "not just me".
I'll just try another MAME from the list (along with that frontend) and see what I can do. I'm in the mood for videogame competition.
