Nice job figuring that out.
I've tried many front ends and there are a few that I like quite a bit. Since my wife is going to be playing this cab a lot, I wanted her input on things. Between the two of us we got it down to Atomic FE, MameWAH, and Maximus Arcade. In the end, however, we'll be buying the full version of Maximus Arcade for its simplicity and its extremely arcadey look.
Still, I won't rule out switching to Atomic FE one day.
