I'm new to all this.. I just d-loaded Launchbox and acquired a Mame rom set... I imported the Mame Rom Set. Launchbox d-loaded the correct MAME for the ROM SET build however, none of the Mame games run.
Double click on, say, "Pac-Man," the screen goes black, and it drops right back to my desktop. Every game does that so far. Any help would be greatly appreciated.
Thanks!
