Description This option will check your roms against the driver in MAME and give you a summary of any errors it finds.

If you add a system name after the -verifyroms 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. -verifyroms 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 -verifyroms >verifyroms.txt. Again you can use this on a specific system by adding the system name after the -verifyroms.
