Dumping System Archives and the Shared Fonts from a 3DS Console
How to dump System Archives and Shared Fonts
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 and system font, 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.

- 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. First the shared font is dumped. Wait for the process to finish and press A again when prompted. 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 are two more folders,
sysdata. Transfer these folders to the User Directory. The folders will merge with the existing
sysdatafolders contained therein. If prompted to overwrite any files, say yes.
