unfixed-info.bin is not a virus. It’s not a secret government backdoor. It’s a slightly moody temporary file—a digital sticky note that says “TODO: finish this.”
| File Name | Purpose | Deals with... | | :--- | :--- | :--- | | | Contains the key for the static , permanent information of an Amiibo | The Amiibo's fixed identity, including character, series, and a unique identifier that never changes. | | locked-secret.bin | Contains the key for the dynamic , changeable information of an Amiibo | User-specific data that changes over time, such as experience points, nicknames, and game progression. |
When setting up TagMo to create custom cards, you will receive an error if these keys are missing.
The file is a critical cryptographic decryption key used by emulation software to read, modify, and clone Nintendo Amiibo data. Alongside its counterpart, locked-secret.bin , this file contains proprietary decryption keys required by applications like TagMo on GitLab to bypass Nintendo's retail encryption. Without it, applications cannot parse the raw data within an Amiibo .bin dump file.
