There are a few ways to distribute 3D screenshots for Nintendo 3DS titles. Some publishers send images you can copy onto a SD card to view in 3D via the system’s photo application.
Nintendo has a better solution for Super Mario 3D Land. Go to this page:http://tinyurl.com/6curhfs with your Nintendo 3DS browser to cycle through screenshots of Mario running into the gate of Bowser’s castle and tightrope walking through a ring of coins.
Super Mario 3D Land comes out on November 13.
