Dumping System Archives and the Shared Fonts from a 3DS Console
Note: although separate in the title, the shared fonts are part of the system archives now. The title was made when they were separate, and is kept unchanged to avoid breaking wiki links. By following the guide below you do get the shared fonts as well.
How to dump System Archives
At this time, Citra can run many games without needing to do any special work on a physical 3DS. However, some games do require files dumped from a 3DS in order to function properly. This tutorial will teach you how to dump the system archives (alongside the config savegame), which are critical for some games, such as Pokemon, to work. These files are copyrighted and are not allowed to be shared, so don’t ask for them on the forum. If you do not own a 3DS to dump the files from, you are out of luck.
threeSD is a tool written to help import data from your 3DS for Citra more conveniently.
Refer to threeSD Quickstart Guide for importing your installed titles, updates, DLCs, save data, extra data, system files, etc. Note that you’ll still need a hacked 3DS with GodMode9 to obtain your keys so that threeSD can decrypt the data on your SD card.
- A 3DS with Homebrew Launcher access
- The 3dsutils homebrew app (Click here for a non-official version)*
- An SD card reader or a way to wirelessly transfer files between the 3DS console and a computer
*There is no official precompiled version of this app, but a non-official build is provided for convenience. Alternatively, you can install devkitPro and compile it yourself from the 3dsutils source code.
- Run 3dsutils via the homebrew launcher.
- Press A when prompted to begin. The system archives will be dumped. Wait for the process to finish, then press A when prompted to be taken back to the homebrew launcher.
- There will now be a
3dsutilsfolder at the root of the 3DS’s SD card. Inside that folder is a folder
nand. Transfer the folder
nandto the User Directory. The folder will merge with the existing
nandfolder contained therein. If prompted to overwrite any files, say yes.
