Ensure the update version (e.g., v1.0.1) is compatible with your base game.

Open your preferred management tool from the Homebrew menu.

After installing the update, do not delete the base NSP from your SD card. The update only patches existing files; it does not replace the entire game. Use Goldleaf or NxNandManager to check that the base game and update appear as separate titles (Base ID: 0100E37012EA8000 , Update ID: 0100E37012EA8800 ).
