* "/nfp_backup.dat" This contains raw data from the [[Amiibo]] NFC data pages. The filesize is 0x001fbd20-bytes. Certain service cmds will trigger writing to this savedata. This entire file is read during [[amiibo Settings]] startup, it's unknown what command(s) actually triggers that. It seems the Amiibo data here is updated each time the Amiibo NFC data is updated, and read each time the Amiibo NFC data is read. Data is written into this savedata when the Amiibo was never scanned on this system before. The data here is probably also updated when the scanned Amiibo NFC data doesn't match the data stored here.

During NFC writing, the NFC data being written can become corrupted if the Amiibo figure is moved outside of range during writing. When this happens, this nfp_backup data can be used to restore the data(which would be the data it was writing when writing failed).
