Hello Here in the documentation they write that you can unzip with partial data overlap. Is it possible to display similar information in your packer, thanks in advance.

Hi. I would really like to switch over to salvador from zx0.exe, but my application requires decompress-in-place so I really need that delta. I've tried the -v and -stats options, and searched the codebase but I can't see anything obvious. Is this possible to do?

You can calculate delta based on the "safe distance" reported in stats. Delta would be (safe_distance + compressed_size) - original_size - or check out my fork which adds delta to the stats output.
