Nintendo 3DS

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

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

  1. SkyDock (todo)

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 (v2.0.0 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.

todo: add info on “front of cart”/box serials (and non-standard carts if relevant)


T = Type
GG = Game code (e.g. DA = nintendogs + cats: Golden Retriever & New Friends)
R = Region (J = Japan, E = USA, P = Europe)
M = Something todo with the production date/run
V = Version (starts at 0)

Easy way to remember where the version number is: fourth character from the right - this works for DS/i carts too.
