The file unfixed-info.bin is a specific data component primarily associated with the Mifare Premium (Amiibo) emulation community. If you have encountered this file, you are likely venturing into the world of backing up or spoofing NFC tags for gaming consoles like the Nintendo Switch, 3DS, or Wii U.
Here is a comprehensive breakdown of what this file is, why it is necessary, and how it functions within the NFC ecosystem. What is unfixed-info.bin?
To understand unfixed-info.bin, you first have to understand how an Amiibo is structured. Every Amiibo contains a small NFC chip (NTAG215) with encrypted data. This data is split into two main conceptual parts:
Fixed Data: Information that never changes, like the character ID.
Unfixed Data: Information that changes based on use, such as game-specific save data, nicknames, or leveling stats.
The unfixed-info.bin file is a decryption key template (often called a "key set"). It contains the specific algorithmic data required by software—like TagMo (Android) or Amiiboss (iOS)—to "unlock" and read the dynamic data portion of an Amiibo dump (.bin file). The "Key" Duo: Locked and Unlocked
In almost all NFC emulation scenarios, unfixed-info.bin does not work alone. It is paired with another file: locked-secret.bin.
unfixed-info.bin: Handles the decryption of the data that the console writes to the tag.
locked-secret.bin: Handles the decryption of the "core" identity of the figurine.
Together, these two files allow third-party apps to verify that an Amiibo dump is legitimate and prepare it to be written onto a blank NTAG215 chip. Why Do You Need It?
Nintendo encrypts their NFC data to prevent unauthorized duplication. Because these encryption keys are proprietary property of Nintendo, developers of backup software cannot legally "hardcode" the keys into their apps.
Instead, the apps require the user to provide their own copy of unfixed-info.bin. Once you "feed" these files into your chosen software, the app gains the ability to: Read existing Amiibo data. Edit character stats or nicknames. Write Amiibo images to blank NFC stickers or cards. Common Issues and Troubleshooting
If you are trying to use unfixed-info.bin and encountering errors, it is usually due to one of three things:
Missing Files: Ensure both unfixed-info.bin and locked-secret.bin are in the same folder. Most apps will show a "Keys Not Found" error if one is missing.
Incorrect MD5 Hash: There are several versions of these files floating around the internet. If the software says the keys are invalid, you may have a corrupted file or a file renamed incorrectly.
File Naming: Some older versions of software specifically look for unfixed-info.bin (with a hyphen) while others look for unfixed_info.bin (with an underscore). Check your app’s documentation to see which naming convention it prefers. Legal and Ethical Note
While owning the software to write NFC tags is legal, downloading unfixed-info.bin falls into a legal gray area because it contains copyrighted decryption keys. Most users extract these keys from their own hardware or find them via community-driven educational repositories.
unfixed-info.bin is the "skeleton key" for the modifiable portion of an Amiibo's memory. Whether you are looking to preserve your collection from wear and tear or simply curious about how NFC tech works, this file is the essential bridge between raw data and a functional game piece.
