OPS2M Demo 67 barcode is 7 11719 65386 8 (even though the cover slip doesn't have a barcode, the number can be generated from the 7 digit part number on the disc and spine e.g. 9653868 - it's a SCEE/first party disc so the first half is UPC 71171xxxxxxx, or GTIN 071171xxxxxxx)

I'll add the other demo because it looks like a good dump, but i must ask you to redump and check again the other disc. According to the ringcode data the dump should match the regular version SCED-50065 version already dumped. I found really suspicious that error count too, honestly. If you can please dump it again, just to be sure.
