### Tärkeää tietoa

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
	
### Tarpeet

* The latest release of [kartdlphax](https://github.com/mariohackandglitch/kartdlphax/releases/latest)
* The latest release of [Luma3DS 3GX Loader Edition](https://github.com/Nanquitas/Luma3DS/releases/tag/v10.2.1)

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, replacing any existing file
  + The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
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. Luo `boot9strap`-niminen kansio SD-korttisi juureen
1. Kopioi boot9strap-`.zip`-pakkauksesta `boot9strap.firm` ja `boot9strap.firm.sha` SD-korttisi `/boot9strap/`-kansioon
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Eject the SD card and put it in the **target 3DS**

#### Section III - kartdlphax

1. Select "Enable plugin loader"
1. Paina (B):tä poistuaksesi Rosalina-valikosta
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`
  - If the source 3DS freezes at this point and you are using a cartridge, try [installing the cartridge to the system](dumping-titles-and-game-cartridges#installing-a-game-cartridge-directly-to-the-system)
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` -> `OK`
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. When prompted, input the key combo given on the top screen to install boot9strap
1. Once it is complete, press (A) to reboot your device

#### Section V - Configuring Luma3DS

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. Käytä (A):ta ja ristiohjainta ottaaksesi seuraavat asetukset käyttöön:
  - **"Show NAND or user string in System Settings"**

At this point, your console will boot to Luma3DS by default as long as the SD card is inserted.
  + Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
  + On the next page, you will copy Luma3DS to internal memory so that you can boot without an SD card.
  + You will **not** need to use your **source 3DS** to complete any further steps on this guide.
