I have access to a few memory card images. I have noticed that when I view them in a hex editor, there seems to be a part of the FAT that appears encrypted.
When I load these images with FMCB's virtual memory card tool all of the files appear. I see several files in the VMCU that have filenames that do not appear in the image.
What's happening here?
Is there some sort of encryption on these cards that the VMCU decrypts when loaded? Could someone point me in the right direction to learn more about this encryption, please?
Is there source available for the FMCB VMCU?
