Reply To: Consolidating my list of MAME and FBA roms

This shows you if a romset is a clone, or a parent.

Parents dont need clone sets to run, but a clone set needs a parent to run.
You could remove all clones, but then you would get rid of games like pacman that is a clone of puckman.

This explains the difference between split and merged romsets.
