When creating a new dat file from a new mame release, I get a general set of messages, "duplicate ROM, 2nd entry ignored" and such. I understand most of them, but one particular message always makes me wonder:

Set: 'xxx'
includes at least one 'nodump' ROM, but ClrMamePro
found valid checksums for it within its parent/clone relationship.
Should ClrMamePro use the found checksum instead of the 'nodump'?

Can anyone please explain this one? If it's a true nodump ROM, what/how did ClrMamePro find something? What did it find? Roman, what do you answer to this question when you're creating a new dat?

Thanks,

Joe
