### Required Reading

GodMode9 is a full access file browser for the Nintendo 3DS console, giving you access to your SD card, the FAT partitions inside your SysNAND and EmuNAND, and basically anything else. Among other functionality, you can copy, delete, rename files, and create folders.

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. 

GodMode9 is powerful software that has the capability to modify essentially anything on your console. Though many of these modifications are locked behind a permissions system, and it is impossible to accidentally perform dangerous actions without deliberately unlocking permissions, you should still follow instructions carefully and keep backups just in case.

## Updating GodMode9

Some of the instructions below are only applicable to the latest version of GodMode9, and as such you should follow this section to update your copy before continuing. Overwrite any existing files.
