Well, I thought I'd check out X-Men on MAME32 (yes, I've never played it ), and got a message saying I was missing several rom files for it to run. But I've looked at 2 or 3 good rom sites, and they have the same 4 files, not the 10 or more I need to run it. I audited the game to see what I need, but the 4 files I have aren't listed. Are those many files encrypted in the four that I have, or is this a special case rom?
