: When you load a character backup, the app uses unfixed-info.bin to read and display the Amiibo’s specific data (e.g., character ID and stats).
Think of it as a "digital pamphlet" or a changelog. When Nintendo releases a new system update, this file is updated to contain information about what has changed. When you open System Settings on your 3DS, the application reads this file to display the current update history, network status, and legal information.
The unfixed-info.bin file is utilized across a broad ecosystem of open-source applications, homebrew software, and hardware emulators. 1. Mobile Amiibo Emulation (TagMo and AmiBoss)
To help provide more specific guidance, let me know the where you found this file. If you want, tell me: unfixed-info.bin
: Also exactly 80 bytes, this file decrypts the unalterable factory-locked sectors of the NFC tag. It handles the base core elements of the chip, such as the character ID, series information, and initial generation parameters.
This includes dynamic, rewritable game properties like character nicknames, training levels, stat adjustments, cosmetic items, and game-specific progress (such as Super Smash Bros. spirit training or The Legend of Zelda companion data).
The file name typically represents a raw, unedited, or non-standardized dump of information from a storage medium or system chip. Common Origins : When you load a character backup, the

This specialized security system ensures that each physical figure maintains its unique identity while allowing for save data and other dynamic information to be recorded.
To view the raw hexadecimal code of the file, use a hex editor. HxD (Windows), Hex Fiend (Mac), or GHex (Linux). When you open System Settings on your 3DS,
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:
If growth continues, roll back to a previous driver version (e.g., 23.12.1 vs. 24.3.1).
The unfixed-info.bin file represents the master key required to interact with the data region of the Amiibo tag. Key Specifications: File Size: Exactly 160 bytes. Primary Companion: locked-secret.bin (exactly 80 bytes).
Because Nintendo protects its physical Near Field Communication (NFC) figures with strict proprietary encryption, the homebrew and backup community must rely on a twin-key architecture to interact with the underlying file systems. Understanding how unfixed-info.bin functions, how it pairs with other components, and how to properly deploy it is essential for anyone interested in custom NFC creation or digital archival.
