The screen saver is awesome. One of the coolest things about attract mode. Still one thing I am not crazy about is it only randomly shows media from current display. Not all displays. It almost makes me think I should have one display and use filters to switch between rom sets.

One possibility is to make an all systems display that list every rom. Default to this display on launch.

Another is to use screensaver.nut. I can't find it though.

I cant' follow this code at all.
