How to Dump and Decrypt 3DS Cartridges

There are two methods to dump game cartridges to run in Citra. Detailed instructions are below for using either method, but in quick summary, the first method requires booting into Decrypt9WIP on a 3DS console, and the second uses the braindump homebrew app accessed via the homebrew launcher.

You must have a 3DS for this, you cannot use a PC alone.

Note on DLC and updates

Dumping a cartridge does not dump DLC and updates for that cartridge. Those are stored on the SD card. See Dumping Installed Titles for more information.


Method 1: Decrypt9WIP

By far the most reliable method of dumping game cartridges.

Required tools

  • 3DS system with the ability to boot into Decrypt9WIP; Read its readme on how to do this using one of the various entry points.
  • SD card with enough space to hold the dump; 8GB or higher recommended
  • SD card reader (preferred), or a way to use wireless file transfer

Instructions

  1. Boot the 3DS to Decrypt9WIP.
  2. Create a folder at the root of the 3DS SD card called files9.
  3. Create a folder inside files9 called D9Game.
  4. Insert the SD card into the 3DS.
  5. Insert the game cartridge to be dumped into the 3DS.
  6. From the root Decrypt9 menu, choose Gamecart Dumper Options, then Dump & Decrypt Cart (trim).
  7. Once this process completes, the game will be a .3ds file inside /files9/D9Game and is immediately usable with Citra.

Method 2: braindump

Any system with Homebrew Launcher access can use braindump to dump cartridges. This method is a little more user-friendly than the previous method, but comes with two caveats:

  1. Digitally installed games that were released after the introduction of system version 9.6 cannot be dumped using braindump.
  2. Braindump can't access all of the game's information, so it generates fake metadata. That is usually good enough for Citra, but not always. If you find the game from braindump doesn't work (while others can play it), or you need a lossless dump for better compatibility, then you need to use method #1 to dump your cartridge.

Required tools

  • braindump
  • 3DS system with access to the Homebrew Launcher
  • SD card with enough space to dump the game card, 8GB or higher recommended
  • SD card reader (preferred), or a way to use wireless file transfer

Instructions

  1. Set up braindump by extracting the braindump folder to the 3ds folder at the root of your 3DS SD card.
  2. Enter the Homebrew Launcher using one of the various exploits.
  3. Choose braindump, then select the game you want to dump. The inserted game card is the first one to appear.
  4. Wait for the process to finish.
  5. Your game will be at the root of the SD card and is immediately usable with Citra.
