: unfixed-info.bin is the digital equivalent of a mechanic's sticky note—scribbled during engine work, useful for the process, but irrelevant once the job is done. It is not a virus, not a critical system file, and not something to lose sleep over. If it annoys you, delete it. If you never see it, ignore it.

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

: While the Amiibo character data itself is "fixed" (read-only), the "unfixed" section contains information that changes, such as in-game save data, levels, or stats.

The unfixed-info.bin file is a . It is not used directly to sign data. Instead, it is used to derive Amiibo-specific keys through a key derivation function (KDF). These derived keys are then used for two main operations:

About * Resources. Readme. * Stars. 80 stars. * Watchers. 3 watching. * Forks. 21 forks. GitHub So easy-4 Step to Make Your Own Amiibo NFC Tags - Xinyetong

: The standard software used to "burn" Amiibo data.

: You must have both unfixed-info.bin and locked-secret.bin (sometimes combined as key_retail.bin ) to decrypt/encrypt the data.

Most apps look for this specific filename. It is best to keep it exactly as unfixed-info.bin to ensure the software recognizes it automatically.

Nintendo utilizes a mix of hardware-specific data and static cryptographic keys to ensure that characters, statistics, and digital items cannot be easily forged or manipulated. The system relies on a derivative of the algorithm. To interact with the data on a raw level, software tools require two key files:

Is it a virus? A corrupted system log? Or just a harmless piece of digital detritus?

Internal chip mechanics that track modifications.

A genuine unfixed-info.bin is extremely small (typically only 160 bytes ).

: It is almost always used alongside another file, locked-secret.bin , which handles the "fixed" data such as the unique Amiibo ID (UID) and character type.
