AtimicFE!

Its easy to use and has many handy features:
*One big ROM list or Separate lists for different emulators or jukeboxes (music/video etc) with same or different menu layouts and graphics.
*Automatically configures emulators and media players.
*Has static or animated menus can be graphically configured however you want it (redesig from scratch).
*Can use your own sound samples for game select etc.
Simple to set-up or can go more indepth if required (extremely versitile).
*Awesome support from the author (answers any quiries about AtomicFE and is knowledgable about emulating in general).
*Completely hides the Windows environment and can be password protected to prevent windows access.
*Has option to shutdown PC after quiting frontend.
*Has a credit manager to allow credit=play-from-menu and can transfer credits to other games automatically
I tried many other frontends and found none better than AtomicFE.
