Copy Protection
Although it is a game about being a pirate, MicroProse obviously didn't want you to pirate their game, so the game implements copy-protection in the form of looking up content from the manual. The immediate effect of failing the copy protection is an increased difficulty in the tutorial sword fight, and a guaranteed failure of said fight (even if you otherwise win). You are given an opportunity to start over, but you can still try to play the game if you fail the protection.

Additionally, the game gives you only 8 crew, and zero guns. Your health is reduced to Fair instead of Fine, and all four countries are hostile towards you. Finally, difficulty (variable DF) is set to "5", which is higher than Swashbuckler. If you overcome this challenge, you will receive 10 officer's portions as Captain  when you divide up the plunder, compared to Captain (Swashbcklr) receiving 8.
