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.

GodMode9

With the onset of sighax and boot9strap, the supported method of dumping game cartridges is GodMode9.

Required tools

  • Latest version of GodMode9
  • 3DS system with boot9strap
  • 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. Set up GodMode9 using SigHax / Boot9Strap. Read its readme on how to do this.
  2. Put the SD card into the 3DS.
  3. From the root GodMode9 menu, navigate to [C:] GAMECART.
  4. Select [TitleID].trim.3ds, then select NCSD image options..., then select Decrypt file (0:/gm9out).
  5. Once this process completes, the game will be a .3ds file inside /gm9/out/ and is immediately usable with Citra.
