How do you extract usable data from archive00XX.dat (BAR)?

Backstory stuff:
After some stuff with got messed up on my system (11.00), I reinstalled the firmware and wasn't worried in any way since I had made a Backup and Restore if something happened. However, apparently the drive I wrote the BAR to was failing (This is the first time I've had issues with this drive), and the console didn't realize this while writing, the BAR wouldn't restore since files 26 and 27 out of 57 were written to bad sectors. After doing a whole bunch of stuff to try to make this work, ending with recovering 99.8% of 26 and 99.99% of 27 with DDRescue, the BAR still refused to restore, so I pivoted to trying to extract the data and manually piece stuff back together.

Actual stuff:

I found a tool that can decrypt the Backup and Restore, but it just turns it into a bunch of blob.bins (Also it was skipping a lot of the archive.dats), and I haven't found any guides on what to then do with those .bin files. And I'm just lost on if and how to get any usable data out of this backup, and was wondering if anyone knew how (Or if by some chance there's still a way, make the BAR restore to the console)?
