I looked at the DOS unpacker and the macutils sources and they look very close and should work OK. I could debug the issue if you provide some CompactPro archives to test.

Ooo. That's exciting.

That's easy. Replace the entire table in crc/zip.c with the normal one starting with 0x77073096 (easily found online).

I also made a Python script to extract the archives.

I found that table here http://www.mrob.com/pub/comp/crc-all.html

Tricksy thing that macutils source. crc/zip.c is a generated file but
the makefile doesn't make that clear. When I did "rm *.o; make" in
the crc directory, it built makecrc first and overwrote my changes
to zip.c, producing a libcrc.a that was still broken. I thought I
might have forgotten to save the changes when everything worked
exactly as before.

With a working CRC this tool seems pretty good. Thanks for the pointer.
