Hacking DIY amiibo cards

[admin]

DIY amiibo cards... created using blank NTAG215 tags and a little bit of dark magic

You need:
- a blank NTAG215 tag sticker (Shop NFC, AliExpress, ...)
- an amiibo dump (dump your own amiibo, download it, ...)
- a way to decrypt/encrypt amiibo dumps (amiibo decryption service, amiitool, ...)
- NFC reader/writer hardware (USB NFC reader/writer, Android smartphone with NFC, ...)
- compatible software to write an amiibo dump to a blank NTAG215 tag (I could not find any so wrote my own)
- a hex editor (HxD, UltraEdit, ...)
- a picture of the amiibo (download it)
- a printer (printer at home, printer at work, photo kiosk, ...)
- a ruler and a cutter knife

Steps:
- decrypt amiibo dump
- use hex editor to change UID in amiibo dump to UID of blank NTAG215 tag
- encrypt amiibo dump
- write amiibo dump to blank NTAG215 tag
- print amiibo picture and cut it out
- put NTAG215 tag sticker on the back of amiibo picture
