Godmode9

A full access file browser for the 3DS console

GodMode9 is a full access file browser for the Nintendo 3DS console, giving you access to your SD card and to the FAT partitons inside your SysNAND and EmuNAND. As of now, you can copy, delete, rename files and create folders. A write permission system prevents you from doing dangerous stuff without noticing.

Warning

This is powerful stuff, so you should not use it if you don't know exactly what you're doing. This tool won't protect you from yourself. On SysNAND, any writing change to your CTRNAND can result in a full brick. Writing changes to your TWLN partition can lead to a partial brick, leading to your console not being able to run DSiWare / DS cartridges anymore. Always keep backups, just to be safe.

How to run this / entry points

GodMode9 can be built to run from a number of entry points, descriptions are below. Note that you need to be on or below 3DS firmware version v9.2 or have ARM9loaderhax installed for any of these to work. Note that for ARM9loaderhax you also need to have a file called slot0x05keyY.bin in the root of your SD card for full compatibility.

• Gateway Browser Exploit: Copy Launcher.dat to your SD card root and run this via http://go.gateway-3ds.com/ from your 3DS browser. Build this with make gateway.
• A9LH, Brahma & Bootstrap: Copy GodMode9.bin to somewhere on your SD card and run it via either Brahma or Bootstrap. Brahma derivatives / loaders such as BrahmaLoader, BootCTR and CTR Boot Manager will also work with this. Build this with make bootstrap.
• Homebrew Launcher: Copy GodMode9.3dsx & GodMode9.smdh into /3DS/GodMode9 on your SD card. Run this via Smealums Homebrew Launcher, Mashers Grid Launcher or any other compatible software. Build this with make brahma.
• CakeHax Browser: Copy GodMode9.dat to the root of your SD card. You can then run it via http://dukesrg.github.io/?GodMode9.dat from your 3DS browser. Build this via make cakehax.
• CakeHax MSET: Copy GodMode9.dat to the root of your SD card and GodMode9.nds to anywhere on the SD card. You can then run it either via MSET and GodMode9.nds. Build this via make cakerop.

If you are a developer and you are building this, you may also just run make release to build all files at once. If you are a user, all files are already included in the release archive.
