Super Mario Maker for 3DS version 1.01 live on the eShop, needed to access Course World modes
If you intend to pick up Super Mario Maker for 3DS on Friday, you may want to grab the game’s first update from the eShop. Indeed: version 1.01 is already live. So long as you have 158 blocks (19.75 MB) of free space available, you should be able to download it.
Super Mario Maker for 3DS version 1.01 isn’t a minor update. In fact, you’ll need it in order to access the Course World. Without it, you won’t be able to play the Recommended Courses or 100 Mario Challenge modes.
Thanks to jikes10 for the tip.
