I installed .220 now and get an invalid BIOS error message when running the games.
I can stick with my .210 version of MAME, but I don't have the whole set anymore, just my favorites. I usually update every 5th new release of MAME, thus deleting the old. That's why at the moment .220 is the set I have, and not anymore the .210
Can't remember where I got the nonag version from anymore, do you know the link? I use the MAMEUI version.
