### Verplicht te lezen

kartdlphax is an exploit for the Download Play mode of Mario Kart 7. It can be used with universal-otherapp to install custom firmware on target devices.

In order to follow these instructions, you will need the following:

- A second 3DS with custom firmware (the **source 3DS**) that is the same region as the 3DS you are trying to modify (the **target 3DS**)
- A physical or digital copy of Mario Kart 7 that is the same region as both consoles
- An SD card for both devices
	
### Wat je nodig hebt

On the **source 3DS** (the 3DS with custom firmware):

* De nieuwste versie van [kartdlphax] (https://github.com/mariohackandglitch/kartdlphax/releases/latest)
* De nieuwste versie van [Luma3DS 3GX Loader Edition](https://github.com/Nanquitas/Luma3DS/releases/tag/v10.2.1)

On the **target 3DS** (the 3DS that you are trying to modify):

* De nieuwste versie van [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/latest)
* De nieuwste versie van [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.3/boot9strap-1.3.zip)
* De nieuwste versie van [standaard Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)

#### Section I - Prep Work (source 3DS)

1. Insert the SD card of your **source 3DS** in your computer
1. Copy Luma 3GX Loader Edition's `boot.firm` to the root of the **source 3DS**'s SD card
  + De hoofdmap van de SD-kaart verwijst naar de bovenste map van de SD-kaart, waarin je alle mappen op de SD-kaart kunt zien, waaronder de Nintendo 3DS map
1. Copy kartdlphax's `plugin.3gx` to the following directory on the **source 3DS**'s SD card, depending on the **region of your copy of Mario Kart 7**:
  - USA: `luma/plugins/0004000000030800`
  - EUR: `luma/plugins/0004000000030700`
  - JPN: `luma/plugins/0004000000030600`
  - Create the `plugins` and `00040000...` folders if they do not already exist
1. Eject the SD card and put it in the **source 3DS**

#### Section II - Prep Work (target 3DS)

1. Insert the SD card of your **target 3DS** in your computer
1. Copy `boot.firm` and `boot.3dsx` from the standard Luma3DS `.zip` to the root of your SD card
1. Maak een map genaamd `boot9strap` op de hoofdmap van je SD-kaart
1. Kopieer `boot9strap.firm` en `boot9strap.firm.sha` van de boot9strap `.zip` naar de `/boot9strap/` map op je SD-kaart
1. Kopieer `SafeB9SInstaller.bin` van de SafeB9SInstaller `.zip` naar de hoofdmap van je SD-kaart
1. Eject the SD card and put it in the **target 3DS**

#### Section III - kartdlphax

1. Power on the **source 3DS**
  - If you are prompted to set up Luma3DS, just press START to save the configuration
1. Once in the HOME Menu, press (Left Shoulder) + (Down D-Pad) + (Select) to bring up the Rosalina menu
1. Select "Enable plugin loader"
1. Druk op (B) om het Rosalina menu af te sluiten
1. Launch Mario Kart 7
  - Ensure that wireless connectivity is enabled
  - kartdlphax should tell you that it is running
1. Navigate to `Local Multiplayer` -> `Create Group`
1. Power on the **target 3DS**
  - Ensure that wireless connectivity is enabled
1. On the **target 3DS**, open the Download Play application (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"}), then select "Nintendo 3DS"
1. Join the group created by the **source 3DS**
1. Select "Start" on the **source 3DS** once it has detected the **target 3DS**
1. Once multiplayer has loaded, navigate to `Grand Prix` -> `50cc` -> (any driver) -> `Mushroom Cup`
1. Wait a while (a percentage should be displayed on the **source 3DS**)
1. If the exploit was successful, the **target 3DS** will have booted into SafeB9SInstaller

#### Section IV - SafeB9SInstaller

1. Wacht tot alle controles zijn voltooid
1. Wanneer daarom wordt gevraagd, voer de toetsencombinatie op het bovenste scherm in om boot9strap te installeren
1. Zodra het voltooid is, druk op (A) om je apparaat opnieuw op te starten

#### Deel V - Luma3DS configureren

1. Your target 3DS should have rebooted into the Luma3DS configuration menu
  + You can access the Luma3DS configuration menu at any time by powering off, holding SELECT, then powering on your device while still holding SELECT
1. Selecteer de volgende opties met de D-pad en de (A) knop:
  - **"Show NAND or user string in System Settings"**

Op dit moment zal je console standaard opstarten naar Luma3DS zolang de SD-kaart geplaatst is.
  + Luma3DS ziet er niet anders uit dan het normale HOME Menu. Als je console in het HOME Menu is opgestart, gebruikt hij custom firmware.
  + Op de volgende pagina kopieer je Luma3DS naar het interne geheugen, zodat je het kan opstarten zonder SD-kaart.
  + You will **not** need to use your **source 3DS** to complete any further steps on this guide.
