StarTropics on the NES. Was it Anti-Piracy or just a fun gimmick?

In 1990, Nintendo both developed and published StarTropics a fun tropical action game adventure game. StarTropics came packaged with a physical letter, which set up the story and was used within the game's plot. During gameplay, the player is prompted to dip this physical letter in water to reveal a hidden code (747), which is required to progress in the game. But Is this letter considered Anti-Piracy or just a fun gimmick to break the fourth wall? In today's episode, we take a closer look at the Anti-Piracy measure's of both StarTropics and StarTropics II Zodas Revenge for the Nintendo Entertainment System. ► Support the Channel -   / modernvintagegamer   Social Media Links : ► X : https://x.com/ModernVintageG ► Threads : https://threads.net/ModernVintageGamer ► Facebook :   / modernvintagegamer   ► IG :   / modernvintagegamer   ► BandCamp : https://modernvintagegamer.bandcamp.com/ #StarTropics #NES #747
