In the latest Iwata Asks, Nintendo president Satoru Iwata explained that when users press the homebutton during a Wii U game, the last scene of gameplay will be saved as a screenshot that you can then share on Miiverse. There’s still no word if you’ll be able to share these screenshots any way else but assuming there’s going to be a mobile version of Miiverse I’m sure users will find a way to save the screenshots to their computers.

Kurisu: I want people to try Miiverse just by itself, and also try posting to Miiverse from games. If you spot a cool scene, you can post a screenshot by pressing the HOME Button. I truly hope people will actively participate in the communities tied to particular games.

Iwata: After you press the HOME Button, you can go from the HOME Button Menu to Miiverse. The game screen that was displayed at the time will be saved as a screenshot that you can post, right?

Kurisu: Yes. There’s a spoiler button, too. We’ve designed it so that people who don’t want to see spoilers won’t have to.

Iwata: There’s also a way to report something that you feel is a spoiler so it should be hidden.

Kurisu: Yeah. I hope people will make use of such features and enjoy aspects of Miiverse that connect to the games.
