The ingenius copy protection
scheme for The Secret of Monkey Island
, similar to code wheel
s used in Star Control
, Curse of the Azure Bonds
and many other game of about the same time. Before the game started it would ask you for a word resulting from a particular combination of face segments you could align on a series of paper circles rotating around the same axis.
What's more, Dial-a-Pirate had a secret message on the inside for scurvy scumdogs who took their wheel apart to photocopy for piracy purposes!
What is it? Well, if I told you, it wouldn't be a secret anymore...
