Use a [save manager](https://github.com/FlagBrew/Checkpoint/releases/latest) to backup any saves for these unsigned (illegitimate) games you care about.
Note that if you have any payload files other than `GodMode9.firm` in the `/luma/payloads/` folder on your SD card, holding (Start) on boot will display a "chainloader menu" where you will have to use the D-Pad and the (A) button to select "GodMode9" for these instructions.
