Hello
I can't seem to find the Widescreen option in Games and Apps Settings, I'm using the latest version (v11.0) and followed the 3DS/2DS: Playing in Widescreen.
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
