Stores game-specific save data (such as Super Smash Bros. fighter levels or Twilight Princess Wolf Link hearts).

It's important to note that you will often see these files referred to with the prefix "retail", as in Have retail unfixed keys or Have retail locked keys in the TagMo UI. This indicates that the keys are from retail, Nintendo-produced hardware. The use of the word "key" suggests these are not generic files but are specific cryptographic components that must be kept secure. For this reason, they are almost never included with the modding tools themselves. Users are typically expected to source them independently for legal and security reasons.

If your unfixed-info.bin file is deleted or corrupted, you might experience the following:

: A multi-tool that can emulate NFC tags. It requires the keys in its internal storage to properly emulate Amiibo formats. Software Applications unfixed-info.bin

Then delete it. Or keep it as a pet. Your call.

Decrypts, signs, and encrypts the rewriteable user data and save states. How Unfixed-info.bin Works Mathematically

: Contains data related to the "unfixed" part of the Amiibo's internal memory (serial numbers and unique IDs). locked-secret.bin Stores game-specific save data (such as Super Smash Bros

: It is almost always used in tandem with another file, locked-secret.bin , which handles the static character identification.

From a technical perspective, unfixed-info.bin is a 80-byte data key. When you scan an Amiibo or open an Amiibo backup file, software frameworks like the Python library PyAmiibo read this master key to generate character-specific keys on the fly. The software executes a multi-step cryptographic pipeline:

Without knowing its origin, purpose, or safety (e.g., it might be part of a specific application, a malware sample, or a log artifact), any review would be speculative and potentially misleading. If you encountered this file on your system, I recommend scanning it with updated antivirus software and checking its parent application’s documentation. If you meant a different product or file, please provide more context (e.g., where it came from, what it’s supposed to do). This indicates that the keys are from retail,
