ISN should be 6108018 but MPF pulls it as EAC0. It's possible that's because the internal serial is usually located on line 3 for Saturn discs, not sure.

Adding attachments for discs dumped with latest WIP and the submission results that show wrong ISN:
T-12504N.txt

^ in this case, ISN should be T-12504N

6107992.txt

^ in this case, ISN should be 6107992
