Nintendo's latest console is full of little easter eggs, such as "thx 2 all game fans" being etched into the internal circuitry of a Pro controller, but the latest one reportedly discovered by hackers is the wildest secret yet. Apparently, if you perform a certain motion with the Joycons on July 11, the same day former Nintendo CEO died of cancer in 2015, it unlocks a hidden copy of Golf for NES, one of the earliest games Iwata, a former programmer, worked on.

(Shout out to Ars Technica for doing a ton of digging on how this was discovered.)

Here's a video showing how it all works:

Does that hand motion look familiar to you? That's because it's one of Iwata's trademarks, a hand gesture made all the time while hosting the company's Nintendo Direct livestreams. It was one of Iwata's many charming quirks.

If your Switch has been connected to the Internet, there is no way to trick the machine into believing it's July 11, so at the moment, this only seems to work on factory fresh Switch hardware. It's unclear if Nintendo ever intended for people to discover this secret, or if there were plans to reveal it later.

Nintendo has yet to comment.

(Side note: This version of Golf even has motion controls, which suggest Nintendo will be updating its classic games beyond simply making them work on the Switch.)

Whatever the intention of the designers who put it there, it's a heartwarming tribute to one of Nintendo's former leaders, one who remains sorely missed.
