TheAmiiboDoctor

Python script for fixing common errors with Amiibo NFC and BIN files.

NOTE:

• This fixes CT in SN3, UID Mismatch, BCC0, BCC1, DLB, CFG0, CFG1, PWD and PACK issues.
• This does not require any keys to fix these issues.
• This script backs up any files it will modify before modifying.
• This script recursively searches for nfc and bin files.
• Can also convert V2 and V3 Flipper NFC files to V4. (Which is what all the testing was done around)
• No Jabs Required, just a few pokes.

Usage:

1. Dry run (safe preview, recommended): python3 TheAmiiboDoctor.py ./ameebo_files

2. Convert v4 (safe preview): python3 TheAmiiboDoctor.py ./ameebo_files --convert-v4

3. Convert Only: python3 TheAmiiboDoctor.py ./ameebo_files --fix --convert-v4 --no-uid --no-bcc --no-password --no-pack --no-dlb --no-cfg

4. Convert and Fix (recommended): python3 TheAmiiboDoctor.py ./ameebo_files --fix --convert-v4

usage: TheAmiiboDoctor.py [-h] [--fix] [--convert-v4] [--no-uid] [--no-bcc] [--no-password] [--no-pack] [--no-dlb] [--no-cfg] directory

I would like to thank @equipter for all the help understanding 0x88 in the 4th position of the UID as well as CT analysis, BCC0 and BCC1 calculations
