Rebuilds the contents of title.db for Nintendo 3DS.

This currently does not interact with title.db directly, https://github.com/wwylele/save3ds must be used manually to extract and rebuild.

This had minimal testing, but it probably works in most cases. File an issue, send me an email, or contact me on Discord if there are problems.


  1. Get boot9 and movable.sed.
  2. Install the requirements: <py3-cmd> -m pip install --user -r requirements.txt
  3. Run the script with the SD card. Example:
    <py3-cmd> rebuild-title-database.py -b boot9.bin -m movable.sed -s F: -o out
  4. Import into title.db with save3ds_fuse and the -i flag.

<py3-cmd> is often python3 for *nix and Python from the Microsoft Store, and py -3 for Windows when installed from python.org.


This copies a clean version of title.db and import.db from title.db.gz.
