I must admit - that I derived more fun from "cracking" such games than
playing them in the old days. Many coders put as much thought into
protecting the game than the game itself. This one may belong to the
group of protection methods in which the loader code modified itself.
All brilliant stuff - and such inspiration!

I had a look to see if I had made any notes about this particular game
but no luck. All I have is a "clean" copy minus its original loader.
