We're actively working on it, and try to get a release out at least every 6months or so.
One could play certain games in current FBA where it would be impossible to play in current MAME
without a considerable amount of frame skipping on older / lower powered systems. Since this is
mosly a hobbiest (as I see it) project, we emulate things that we would personally like to see in
this emulator.
