Nintendo 3DS

Dumping Nintendo 3DS carts is fairly easy, and can either be done using a DS flashcart or through a software exploit.

You will need an SD card 8GB or larger for this.

  1. 3DS console (GodMode9)
  2. SkyDock

The following method work on all models of the 3DS, 2DS and New 3DS handhelds.

Follow the instructions over at 3DS Hacks Guide for more details on how to get your handheld ready, by enabling it to run 3DS-mode bare metal ARM9 homebrew, and make sure the latest stable GodMode9 is installed/present (v1.9.3pre1 or later).

Note that you do not necessarily need to install custom firmware to run GodMode9 - you can stop following the 3DS Hacks Guide once you get to the point of being able to run a .firm file (or equivalent file for that particular exploit). But for convenience, you may want to follow the 3DS Hacks Guide to the end, so you can easily run GodMode9 at boot.


  • Launch GodMode9 by pressing (Start) and then the power button
  • Navigate to [C:] GAMECART
  • Copy the .3ds file without trim in its name and the .txt file to the SD card. If split files show up (for 3DS games that are larger than 4GB), copy all the split parts to the SD card.
  • If you copied the .3ds file in split form, you need to combine them using copy /b part1 + part2 combined on the Windows command line or cat part1 part1 > combined on the Mac OS or Linux terminal. Otherwise, you're done.

  • Cart ID: Get this from the .txt file provided by GodMode9
    • Technical note - GodMode9 displays these in the little endian byte order (i.e. first byte is the chip manufacture byte), which makes sense as the 3DS CPU is little endian (as are the DS and DSi's CPUs). But the gbatek documentation of the cart protocol displays these in big endian byte order (i.e. last byte is the chip manufacture byte).
  • Box Barcode: Keep the spaces. It should be verified against the barcode itself by using barcode scanning software and using the check digit.
  • PCB Serial: Use for for the triangle character, one space character ( ) for each empty “slot” and for the small circle characters (which don't always appear).

You can submit your dump info to the No-Intro database, via the forum, email or directly via a database account if you have one.
