Nintendo Amiibos use encrypted NFC data. To interact with this data using third-party software, the app must "unlock" the files using specific retail keys. While the software itself is legal, these proprietary key files are copyrighted by Nintendo and are therefore not bundled with the apps. It is almost always used alongside another file called locked-secret.bin Alternative Names:

If you generated the file yourself by dumping data from your own hardware, it is completely safe.

Nintendo designed Amiibo to be both secure and functional. The NTAG215 NFC chips inside the figures use a proprietary encryption system that Nintendo controls. This system splits Amiibo data into two categories:

This region contains information unique to the specific physical tag or data that changes over time.

To get started, you will need to place three types of files on your Android device (typically in a folder like Downloads or a dedicated Amiibo folder): unfixed-info.bin

However, these applications do not ship with the cryptographic keys built-in. The Software Sandbox

The file is usually marked as hidden and system. If you can see it, you have enabled "Show hidden files, folders, and drives" in File Explorer. Disable that, and it will disappear from view.

In 90% of cases, unfixed-info.bin is a temporary file and can be deleted without consequences.

If you receive "File in use" errors, boot into Safe Mode and delete from there. Nintendo Amiibos use encrypted NFC data

This dual-layer encryption ensures that both the static identity and the dynamic progress data of an Amiibo are properly protected and authenticated.

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

The Ultimate Guide to unfixed-info.bin: Custom Firmware, Amiibo Emulation, and Data Structures

. The file is essentially a temporary artifact. Deleting it will have zero impact on gaming performance, video playback, or stability. The worst that happens is that AMD’s next update recreates it from scratch. It is almost always used alongside another file

This allows you to inspect the file headers and search for text strings hidden in the binary code. 2. Specialized Emulators or Flashing Tools

If you are trying to "draft" or set up these files for the first time, follow these steps:

Understanding how unfixed-info.bin works is essential for developers, hardware enthusiasts, and power users who want to back up their physical collections or emulate Near Field Communication (NFC) tags. What is unfixed-info.bin?

: It is almost always used in tandem with locked-secret.bin . Together, these two files contain the retail keys necessary for standard Amiibo operations.
