We now have two proven methods for locating the version of a GameCube disc. It's printed on the ring code of the actual disc and it's located at offset +7 from the beginning of the dump. A difference in CRC32's is going to first alert us to a variation between two dumps so assuming the two dumps are good the next step would be to compare the ring codes version number and if those aren't available verify by checking at offset +7. So I fail to understand the reason for DOL MD5's checksums why would you ever use this information now. It even generates the same checksums for Disc 1 and Disc 2 of a game containing two discs. How is this helpful in anyway?
Coming from someone who dumps a lot of GC discs it would save me time not to have to rename my dumps then go into DOS just to check the DOL MD5 unless someone can give me a reason for it still to be useful. I'm sure at the time it was a useful tool and I appreciate Organic's effort but now the information it produces seems unnecessary. I would like to see ring codes mandatory for submission of new GC dumps and DOL MD5 optional.
