A new 3DS update was recently released, and it adds the Amiibo settings menu to the 3DS, 3DS XL, and 2DS! (Sorry for the bad quality)
Save/Load Menu Layout
Now you can save your layout of the Home menu, which includes the theme and how things are arranged, and use a different one when you want to. You can save up to eight different layouts, and load them whenever you want. But it does remove the menu layout you are currently using, so make sure to save it first.
Theme Shop
New themes were added to the theme shop as well as more categories so that you can search by series. I love the new Kirby themes.
Amiibo Settings
That's all that was in the update. Hopefully the NFC reader/writer will be released soon. When it is released, people who don't have a New Nintendo 3DS will be able to use Amiibo.
Have A Successful Amiibo Hunt!
