Supported games offer one of two kinds of Amiibo compatibility; the ability to access an Amiibo toy's NFC tag and store data, and read-only recognition. Each Amiibo toy largely corresponds to a specific game that can access its storage space, though some may have multiple games that can use it. However, each Amiibo toy can only store data from one compatible game at a time, meaning data must be deleted to use it with a different title. For example, a Mario Amiibo figurine containing data from Super Smash Bros. for Nintendo 3DS and Wii U must have the data for that game deleted to store data from Mario Party 10. Many games offer compatibility with specific Amiibo toys on a read-only basis, allowing for additional content to be unlocked in that game. For example, using certain figurines with Mario Kart 8 or Mario Kart 8 Deluxe unlocks Mii costumes based on the corresponding character. Multiple variations of the same character offer the same compatibility, although special variations can unlock unique content with specific games. Existing Wii U and 3DS games can receive updates for Amiibo functionality. Due to their co-development effort on Super Smash Bros. for Nintendo 3DS and Wii U, Bandai Namco Entertainment were the first third-party publishers to embrace the Amiibo concept in some of their own games.
