With the standard default sharp rom backups, I am able to open them with 7-zip and extract and manipulate files.
With the cacko rom backups, 7-zip tells me that the backup is not a supported archive.
This is strange, because the backup/restore programs appear to be the same in both roms.
I really like the idea of being able to work with the backups.
Sometimes it gets me out of a real mess.
Would anyone have any ideas on this?
