Okay, I have Atomic and GameEx, and whatever other front ends, pointed at some version of command-line Mame. When I run a game, it gives this long scrolling cmd box until, apparently, it's run the whole list of games available in Mame - not in my folder - but that Mame can play, regardless where in the list the game I'm playing is...and then the game starts.
However, if I point to Mame32, the game loads, immediately. Any ideas on this?
