Description This option will generate a complete list of all the clone systems supported by MAME giving the clone system name and which system is the parent set of it.

If you add a system name after the -listclones it will only tell you the information for that system. There is a wildcard option that will let you generate a list containing systems of certain names e.g. -listclones puck* will generate a list of systems starting with puck. If you want to direct the list to a text file then use this command mame64 -listclones >listclones.txt. Again, you can use this on a specific system by adding the system name after the -listclones.
