Oops, I think I know that guy ;-)

Karateka was an interesting crack as it used some funny tricks to
prevent the ugly pirate from boot tracing the application.
What is also funny with Wings of Fury is that, depending on how you
follow the code, you may go to the next boot stage or... nowhere!

The most difficult still remains Hold-Up (Infogrames, written by a
former brilliant French pirate) as it contained all the toughest on-
disk protection schemes but also trick off-disk ones.

I would definitively say that those that require a rewrite of the
original RWTS and disk and RAM reorganisations are among the most
difficult ones also. For instance, Micro League Baseball uses a simple
4*4 encoding scheme but uses all the RAM. And programmers/pirates know
that reading/writing 4*4 nibbles is fairly easy and short in RAM.
Moving to 6*2 nibbles involve more RAM usage... which you don't have.
Grrrr!

I do not want to talk about interpreted (M-CODE) or compiled (Pascal)
languages now, that is another tough subject!
