How to Dump and Decrypt 3DS Cartridges

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.


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


  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.
