I got the checksum error when trying to unzoo them, but it gave me a
line number to check (zoo for pc - very handy for multipart archives).
The trouble is that one line got split over two.  To fix this you just
have to edit the file at that line (I think it was about line 430 in
part 6 in the #2 archive - I had no problem with #1), removing the line
feed/cr.  I don't think that the programs will run correctly if you
don't do this - it will work most of the time, but when it gets to a
certain part of the code (e.g. getting the artifact ...) it may crash.
I'm not totally sure about this, but I'd make the alteration if I were
you.
