Kotaku - On the third floor of Nintendo’s U.S. headquarters, next to the conference rooms named after Mario and Donkey Kong, there’s a door that you can’t open. There’s no boss key or warp pipe here—unless you’re one of the handful of people with a high-security keycard, you’re not getting in.P
If you were to somehow break the seal, you might uncover a treasure trove of Nintendo secrets—scripts and code belonging to unannounced games from the most iconic video game franchises in the world. Maybe you’d stumble upon the Wii U version of Zelda, unfinished and unpolished. Maybe you’d find some hardware revision that hasn’t been unveiled yet. Maybe you'd run into one of the talented writers responsible for many of Nintendo’s most memorable moments.
