--from names either a producer (mgba, duckstation, pcsx2, or any of the 122 cores in the registry) or an input format (ps1, raw). A producer says who wrote the bytes; the format is still detected from the bytes themselves.

--rom reads a ROM's header for a title and product code and hashes it; --dat resolves that digest against a No-Intro, Redump or TOSEC catalog to get a canonical name.
