Switch version 4.0.0 seems to remove the NES Golf Iwata tribute
Several months ago, hackers discovered that the Switch has a special tribute to late Nintendo president Satoru Iwata. On July 11, the day of Iwata’s passing, system owners could unlock Golf from the NES. You simply needed to perform his signature “direct” motion from the older Nintendo Direct presentations on the home menu.
For whatever reason, Nintendo decided to remove the Easter egg as of version 4.0.0. That firmware has been around since late October, but its removal was only detected recently. The official code was deleted from the home menu, and all code was overwritten. Even when you attempt to load it manually, an error will be returned.
Why did Nintendo ultimately remove the tribute? That we can’t say. We can only hope that it will return closer to July 2018.
