I just lost a bunch of source-code files, it seems :-< Or, at least
the latest version thereof.

I have this THINK C project (the Crystal Cave game) which I stuffed and
put on a shelf in August.  It finally hit comp.binaries.mac this week,
and some folks decided to take me up on my offer of source for the
curious, so I took it off the shelf.

Everything looks fine until I actually try to extract things.  I have not
tried them all, but the first five anyway give me an error message about
checksums in the resource fork, and somewhere around the second attempt
will bomb the Mac.  This is very bad.

There's enough good information for the trashed file to be on the desktop
with the correct icon when I'm done, but as near as I can tell, the files
are unusable.

Does anyone have any information or experience about such stuff?  Is there
any hope of recovering the files?  All stuffing and unstuffing is being
done by StuffIt 1.5.1. under System 6.0.2 on a MacII.

Lest you think I'm a total nitwit, let me assure you that there is another
form of backup, but it's one update level old, and I don't have perfect
memory of what got changed where to make the release version, so I would
surely prefer to recover the files.
