### 必讀事項

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
	
### 必備項目

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

* 最新版的 [kartdlphax](https://github.com/mariohackandglitch/kartdlphax/releases/latest)
* 最新版的 [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):

* 最新版的 [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/latest)

* 最新版的 [一般 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
  + 「SD 卡的根目錄」指的是你的 SD 卡含有 Nintendo 3DS 資料夾的目錄，而非該資料夾內部
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**:
  - 美版： `luma/plugins/0004000000030800`
  - EUR: `luma/plugins/0004000000030700`
  - 日版： `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. 在 SD 卡的根目錄底下建立一個新的資料夾 `boot9strap`
1. 解壓 boot9strap `.zip` 的 `boot9strap.firm` 及 `boot9strap.firm.sha` 檔案至 SD 卡的 `/boot9strap/` 資料夾中
1. 將 SafeB9SInstaller `.zip` 中的 `SafeB9SInstaller.bin` 複製到 SD 卡的根目錄
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. 按『B』退出 Rosalina 選單
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. 將 **3DS 目標機** 開機
  - 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. 等待所有的項目檢查完畢
1. 出現提示時，輸入上方螢幕所顯示的按鍵組合以安裝 boot9strap
1. 過程結束後，按下『A』重啟主機

#### 第五節 — 設定 Luma3DS

1. Your target 3DS should have rebooted into the Luma3DS configuration menu
1. 透過方向鍵及『A』以開啟下列選項：
  - **"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.
