Nintendo protects the data on its physical figures using a mix of fixed hardware properties and encrypted internal storage. The data structure of an Amiibo is divided into two distinct zones:

Every NFC chip has a unique 7-byte concrete identifier (UID) hardcoded by the manufacturer. This data cannot be changed. Fixed Data To manipulate this data, two corresponding master keys

Nintendo utilizes Near Field Communication (NFC) technology inside Amiibo figures and cards, relying strictly on . These chips contain 540 bytes of raw storage data. To prevent unauthorized cloning and data manipulation, Nintendo splits the data structure into different security tiers:

Place unfixed-info.bin and locked-secret.bin in a folder on your phone. Open the App: Launch TagMo or your preferred NFC tool. Link the Keys: Go to Settings -> Import Keys. Nintendo protects the data on its physical figures

Allows you to change the properties, level stats, and cosmetic attributes of saved character backups.

The unfixed-info.bin file is a small but vital piece of the Nintendo homebrew puzzle. By serving as the key to the unfixed, unique data regions of an Amiibo's NTAG215 chip, it bridges the gap between raw hardware manipulation and seamless software emulation. Whether you are preserving a physical collection of rare figures or exploring custom NFC projects, understanding how this file works ensures a smoother, error-free experience in the world of console modding.
