The error is from libarchive (not zip or unzip) - it thinks the file(s) use
the (legacy, unsupported) implode compressoin method. I don't recall changing
the version of libarchive used with SBBS between v3.20 and current dev
(v3.21a) - so that's surprising.

Maybe send me a copy of one of the files so I can take a look-see?

You could also use the archive.js script (with jsexec) to test the files with
libarchive.
