I wrote a quick little script to Backup/Restore the Luma3DS Boot Animation. This will be handy for those who have a Boot Animation setup (Not splash screen) and need to update their Luma installations.
You can view the full post over on the gbatemp forums:
Luma Updater was updated recently to v2.2, although as there was no update to Luma3DS itself, updating is still recommended.
If you want to update the app, simply launch it while you’re connected to the Internet and follow the on screen instructions.
