### 중요

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
	
### 준비물

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

* 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)

#### 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
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. SD 카드이 루트에 `boot9strap` 라는 이름으로 새 폴더를 생성해 주세요
1. SD 카드에 있는 `/boot9strap/` 폴더에 boot9strap `.zip` 파일 안에 압축되있는 `boot9strap.firm`과 `boot9strap.firm.sha`을 복사해 주세요
1. SafeB9SInstaller `.zip`의 `SafeB9SInstaller.bin`을 SD 카드의 루트로 복사해 주세요
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. (B)를 눌러 Rosalina 메뉴를 나와 주세요
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. 모든 안전 검사가 끝날 때까지 기다려 주세요
1. 메시지가 나타나면, boot9strap을 설치하기 위하여 화면에 주어진 키 조합을 입력해 주세요
1. 작업이 완료되면 (A) 를 눌려 기기를 재부팅해 주세요

#### 섹션 V - Luma3DS 설정

1. Your target 3DS should have rebooted into the Luma3DS configuration menu
1. (A) 버튼과 십자 패드을 이용해 다음 설정을 설정해 주세요:
  - **"Show NAND or user string in System Settings"**

이제 기기는 SD 카드가 삽입되 있는 한 Luma3DS를 기본으로 부팅 됩니다.
  + Luma3DS는 HOME 메뉴하고 똑같이 보입니다. 만약 기기가 HOME 메뉴로 부팅 됬다면 커스텀 펌웨어가 설치되 있습니다.
  + 다음 페이지에서는 SD 카드 없이 부팅 할 수 있도록 Luma3DS를 내장 메모리로 설치할 것 입니다.
  + You will **not** need to use your **source 3DS** to complete any further steps on this guide.
