===== Introduction =====
{{wst>carts_important_notes}}
Dumping DS and DSi carts is reasonably easy if you have a 3DS or DSi, but is more involved if you only have a DS available.

===== Methods =====

  - [[#Method 1 - 3DS console|3DS console]]
  - [[#Method 2 - DSi console|DSi console]]
  - [[#Method 3 - DS console via Wi-Fi|DS console via Wi-Fi]]
  - [[#Method 4 - DS console via slot-2 flashcart|DS console via slot-2 flashcart]]

==== Method 1 - 3DS console ====
=== Tools ===
  * A Nintendo 3DS (including New 3DS/2DS/New 2DS) with a method to run "bare-metal" ARM9 software. Methods include having a [[https://3ds.hacks.guide/|custom firmware]] installed or using a DS flashcart with [[https://3ds.hacks.guide/ntrboot|ntrboothax]].
  * SD card
  * [[https://github.com/d0k3/GodMode9/releases|GodMode9]] (v2.0.0 or later)

=== Dumping ===
  * Turn off the console
  * Insert the game
  * Boot your console into GodMode9
  * Navigate into "GAMECART"
  * Copy the .nds.enc file and the .txt file to the SD card.

==== Method 2 - DSi console ====

Follow the instructions over at [[https://dsi.cfw.guide/|DSi CFW Guide]] for more details on how to get your handheld ready to handle homebrew, and make sure the latest stable [[https://github.com/DS-Homebrew/GodMode9i|GodMode9i]] is installed on your SD card.

Dumping
  * Launch GodMode9i by using [[https://github.com/DS-Homebrew/TWiLightMenu/|TWiLight Menu++]].
  * Navigate to **NDS GAMECARD**, press **A**.
  * You'll see the following menu:

<code>
Dump NDS card ROM to
"s:/gm9i/out"?
(<A> yes, <Y> trim, <B> no,
 <X> save only)
</code>

  * Press **A** to dump the cart to your SD card.
  * Once it's finished, you can turn off the console and copy the files to your computer from the **gm9i/out** folder on your SD card.

==== Method 3 - DS console via Wi-Fi ====

Using the Wi-Fi version of the [[https://archive.org/details/wooddumper-r89|wooddumper]] homebrew, you can dump DS carts over FTP using a DS or DS Lite.

Requirements:

  * DS or DS Lite console
  * A way to run homebrew (if you don't have a flashcart, you can [[https://hiccup.miraheze.org/wiki/How_to_run_DS_homebrew_using_Download_Play|run homebrew using Download Play]] if you have certain hardware)
  * Wi-Fi connection that can be set to WEP security or unsecured
  * PC/smartphone/tablet that can connect to said network
  * FTP client software on said PC/smartphone/tablet (you can often use the built-in browser or file manager by entering the IP address and prefixing it with ''ftp:%%/%%/'').

=== Wi-Fi Setup ===

  * Create a WEP or unsecured hotspot using your router, smartphone/tablet or PC. There's no need to have it connected to the internet.
  * Make sure you have a device connected to the hotspot. There's no need for this to be connected to the internet via another connection either.
  * Use a Wi-Fi-enabled DS game (or [[https://archive.org/details/ugoku-memo-tobari-japan-nintendo-channel|this]] free Nintendo Channel demo) to setup the Wi-Fi connection on your DS. It'll say that the Nintendo Wi-Fi Connection service is discontinued, but this doesn't matter, as we don't need Nintendo's online service or any internet. If the auto-setup ("Search for an Access Point") option doesn't work, try the manual one.

=== Dumping ===
  * Run wooddumper.
  * Follow the on-screen instructions regarding inserting you cart.
  * Open the on-screen ip address in your FTP client.
  * Copy the .nds and .txt file to your computer.


==== Method 4 - DS console via slot-2 flashcart ====

=== Tools ===
  * A Nintendo DS or Nintendo DS Lite with a slot-1 flashcart
  * A slot-2 flashcart compatible with your slot-1 flashcart.
  * [[https://archive.org/download/wooddumper-r89|wooddumper]]

=== Dumping ===
  * Run wooddumper
  * Follow the on-screen instructions regarding inserting the cart
  * Insert your slot-2 flashcarts SD card to your PC's SD card reader / connect your slot-2 flashcart to your PC
  * Copy the .nds and .txt files to your PC.

===== For Reference: Identifying Game Versions =====

todo: add info on box serials (and non-standard carts if relevant)

{{:carts:nintendo:ds:cart_front.jpg?260}}

Front of cart serial\\
**SSS-CCCC-RRR**\\
e.g. NTR-A2DP-EUR

S = System (NTR = DS, TWL = DSi-exclusive/DSi-enhanced)\\
C = Gamecode (see the first four characters in the "back of cart serial" section, although sometimes the gamecode here is incorrect and won't match that)\\
R = Region \\

Region Codes:
^ Region     ^ Region Code       ^ 
| Japan   | JPN     |
| USA   | USA |
| Canada    | CAN |
| Europe | EUR | 
| United Kingdom | UKV | 
| France | FRA |
| Korea | KOR |

\\
\\
{{:carts:nintendo:ds:cart_back.jpg?260}}

Back of cart serial\\
**TGGRUVXMM**\\
e.g. A2DPN0J08

T = Type (A/B/C = Normal, D = DSi-exclusive, DS/DSi-enhanced with infrared hardware, T = Unknown, U = Tool/Utility, V = DSi-enhanced, Y = Unknown)\\
GG = Game code (e.g. 2D = New Super Mario Bros.)\\
R = Region (J = Japan, E = USA, P = Europe, K = Korea)\\
U = Unknown ("N" in all known cases)\\
V = Version (starts at 0)\\
X = Unknown ("J" in all known cases)\\
M = Production site/factory ID?

Easy way to remember where the version number is: fourth character from the right - this works for 3DS carts too.

PCB serial\\
**Meaning is unknown**\\
e.g. ▼ CS  A-1  C01-10\\
sometimes a dot character (•) is used

ROM chip serial (first line)\\
**XYYWW...**\\
X = Unknown\\
Y = Manufacturing year?\\
W = Manufacturing week?
