Well, it is Mame 0.122u1 so it's really old, but I haven't seen how I can easily update my romset from the current version or even tell what version it is very easily in order to run a newer Mame. I did read the sticky on updating them, but it is mentioned even there that there is no easy way to tell the version of the currrent romset. Do you know of a way? If they are as old as the Mame version than I can't imagine doing that many updates anyway.
If I were to acquire roms for the newest version of Mame, can I just add another platform in Launchbox and run the newer roms and Mame out of that without impacting anything else, just by naming that a different platform name?
