Oh... wow, I had no idea that's possible. I didn't think you could generate CRCs from other CRCs... given that two completely different files with completely different content could potentially have the same CRC. Well, that answer dashes my hopes of this functionality getting added to the database (unless we want to manually add the full disc CRC to every multi-track game!), but does certainly answer the question. Thanks :')

The combined CRC32 value is generated on the fly, none of the full disc hashes is actually stored in the database, except discs with one track abviously.

Air Combat for the PS1 has the hash 5b9d9183, for example. But if I search for it, Air Combat isn't found.
