I guess that is what I have to do then...
but it's not a picnic when the DAT contains 10955 ROMs divided to only 360 sets. This is not emulation, it's the old Sierra games like Space Quest series, etc, etc... there's "ROMs" over 300Megs that is in more than one set.

I just thought I requested a feature that would be appriciated by many and make ClrMame Pro more complete.
