Change the release title Zelda: Breath of the Wild continues to reveal legal secrets to this day, and the Twitter user @HEYimHeroic has just unearthed another: the game’s NPCs use an updated version of the Mii face creation tool, which first appeared when the Wii was launched in 2006.
It makes sense for Nintendo to use an existing tool to streamline the character creation process for the game, but it is still somewhat surprising that a system created 15 years ago is still being used in Nintendo’s AAA software.
It is also interesting because it means that hackers who are disassembling the game on the PC (via emulation) can ‘inject’ new faces into the game now that they understand how those faces are created. Expect to see some famous faces coming in modified versions of Breath of the Wild soon, then.
