Topic: Question about imagediff/imagepatch tool

Hi, no account request but a question that probably only this forum can answer because these tools were obviously developed by a memer.
I've got some patch files created with imagediff to fix old scene dumps.

Problem is I don't have access to a windows machine, only linux.
Is there anything known about the patchfile format of imagediff?
Is it following any standard format so I can use an existing linux program with it?

Thanks for any help.
