I don't know where you get the idea that it is beyond the ability of most
"crackers."  Regardless of copy protection or information being seeked/verified
or even multiple/series of CRC checks for original code integrity, they normally
just knock out the verification routine in total -- not attempt to return any
kind of spoofed validation information.

The real battle is hiding & protecting the copy protection itself.
