Unused feature has been hidden in Animal Crossing for nearly two decades.
Replacing that memory gibberish with a carefully crafted memory card file lets you load arbitrary NES games through Animal Crossing.
Fans of the early 2000's era GameCube version of the original Animal Crossing likely remember the game including a handful of emulated NES titles that could be played by obtaining in-game items for your house. What players back then didn't know is that the NES emulator in Animal Crossing can also be used to play any generic NES ROM stored on a GameCube memory card.
Security researcher James Chambers discovered the previously unused and undocumented feature buried in the original Animal Crossing game code and detailed his methodology and findings in a technically oriented Medium post this week.
