I was able to use jojodiff to merge two partial images of a multi-megabyte 9-track tape (with dropped bytes and parts of blocks in different places) into a valid correct image in less than a day! Without jojodiff, it would have taken me weeks.

Perfect. Everything I needed (and was very hard to find for Windows!): a quick command to generate a binary patch file delta to be applied on the original file.

Hello, I tested your software on both Intel and ARM based (Raspberry PI) and I was able to develop a prototype Software Over The Air solution using this solution. I have done numerous testing by creating diff and send the diff over the air and I was able to recreate original image. I do sha256sum comparison. Great work. I need a clarification, license information in sourceforge.net say your software is GPL 2.0. But the copying file in source pack say that it is GPLv3. Please clarify (my email: c.n.aananth@gmail.com) Regards, Aananth
