ARiD is an acronym for Arcade Rom ID.
It’s an identification tool used to check integrity and to spot unknown arcade boards from their EPROM dumps.
It’s always a work in progress but it recognises all the games the loaded MAME database knows.
It also performs checksum calculations for the FLUKE 9010A Micro System TroubleShooter. It’s very useful for repairing vintage computers and arcade boards.
