This is the tutorial keygen: the same kind of puzzle as Saturday and Sunday, made as gentle as it gets.

Set your handle first (the CRACKER line). The serial follows from it, so a different handle needs a different serial.

The trick is called serial fishing: let the program work the answer out, and read it off just before it compares.

Greets to every trainer maker who ever froze a health bar, every cracker who signed a release with an NFO, everyone who learned assembly one jump at a time, the keygen musicians, and you for reading this far.
