Over the weekend, data miners said they discovered a copy of Golf, the 1984 game for the Nintendo Entertainment System, in the system directory for the Nintendo Switch. This would mean every console has a copy of the game. Nintendo hasn’t confirmed or commented on the game’s presence, but there’s a very touching theory as to what this is all about.

Golf was programmed by the late Satoru Iwata, the former Nintendo president who died in 2015. Justin Epperson, a senior producer for the Japanese localization company 8-4, Ltd. said Japanese Twitter believes this to be a kind of memorial to Iwata.
