So yea, the title says it all pretty much. I recently did a large rom dump into LaunchBox (i'm new to this platform), and some of the games have multiple versions within the ROM Zip file and only 1 or 2 of those files seem to work when I launch directly from the Mame software. For instance; Heavy Smash has a Europe, Japan, and Asia version, only Japan and Asia will work inside of Mame, but it seems as if LaunchBox wants to launch the Europe version. Is there a way to get Launch box to load this particular "version" or am I way off?
