With the arrival of the New Nintendo 3DS XL this coming Friday, Nintendo just released the latest update for its hit title Super Smash Bros. for Nintendo 3DS.
The latest update includes Share Mode, amiibo support for the New Nintendo 3DS XL, and other miscellaneous issues.
Unfortunately, Nitendo has not announced the release date for the NFC add-on for the original Nintendo 3DS and its various models.
Perhaps the most important new feature in the update, the Share mode, will let users post photos, replay info and Mii Fighter data to share with friends. This Smash 3DS Update 1.0.5 is a must-have.
