Um.. Then he needs some program to strip off executable parts. I've
written one, but it is very simple and dumb, because I wrote it
especially for masyanya (flash series popular in Russia).

It is in attachment.
Though I've seen it work for over a hundred files, it tends to fail on
some, especially on newer or bigger ones. No complains!
