PS: Do you think different toolstamp / same ringcode CD need to be dumped?
I wouldn't expect any difference for the same ringcode/different toolstamp cases, though, the ultimate goal is to dump and catalogize every difference.
On another hand, I've met a case, when 2 discs with identical ringcodes had a slightly different data, so you can't be 100% sure about every disc without dumping it - http://redump.org/disc/2554/
Yes REDump base is almost complete but I think I still have a few games to add.
You can add the verifications of the already dumped ones as well.
