{: .notice--info}

This process will overwrite your Steel Diver: Sub Wars save file, if you have one. If you wish to preserve your Steel Diver: Sub Wars game data, you should make a backup of your `00000001.sav` file before overwriting it.

### 操作步骤

#### 第一步 – 准备工作

In this section, you will copy some of the files that will be used to launch the Homebrew Launcher.

1. Power off your console
1. 将你的 SD 卡插入到电脑
1. 解压 Luma3DS `.zip` 里的 `boot.firm` 和 `boot.3dsx` 到你 SD 卡的根目录
  + 根目录指的是你点进 SD 卡看到的目录，你可以在这个目录下看到 Nintendo 3DS 文件夹，但请不要点进去
1. 在 SD 卡根目录创建一个名为 `boot9strap` 的文件夹
1. 从boot9strap `.zip` 文件中复制 `boot9strap.firm` 和 `boot9strap.firm.sha` 到你SD卡的 `/boot9strap/` 文件夹中
1. 从 SafeB9SInstaller `.zip` 压缩包中复制 `SafeB9SInstaller.bin` 到 SD 卡根目录下
1. Copy the `steelhax` folder from the `Steelhax-release.zip` to the root of your SD card
1. Copy the otherapp payload for your model/region/version from `otherapps_with_CfgS_11.17.zip` to the root of your SD card, then rename the payload to `otherapp.bin`
  + Do not add the `.bin` extension if you do not already see it
1. Copy `movable.sed` from your computer to the root of your SD card
1. 检查 SD 卡的根目录是否存在一个名为 `3ds` 的文件夹，如果没有则手动新建一个
  + This folder stores homebrew applications and data; it is different from the `Nintendo 3DS` folder that the console automatically generates
1. Copy the `nimdsphax` folder from the nimdsphax `.zip` to the `/3ds/` folder on your SD card
1. Reinsert your SD card into your console
1. Power on your console

#### Section II - Steelminer

In this section, you will create a hacked Steel Diver: Sub Wars save file that, when used, will load the Homebrew Launcher on your console.

1. Launch "Steel Diver: Sub Wars" once and select a Mii to initialize your save file
  + Decline the game update when prompted
  + If you have already updated the game, use the Data Management menu of the System Settings to delete the update
1. Exit "Steel Diver: Sub Wars"
1. Power off your console
1. 将你的 SD 卡插入到电脑
1. Open [the SteelHax Save Tool website](https://3dstools.nhnarwhal.com/#/steelhax) on your computer
1. Select your `movable.sed` file
1. Select your region based on your console
1. Select "Build and Download"
1. Wait for the process to complete
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `<8-character-region>` -> `data` on your SD card
  + **EUR Region**: `000d7e00`
  + **JPN Region**: `000d7c00`
  + **USA Region**: `000d7d00`
1. Copy the newly downloaded `00000001.sav` file to the `data` folder on your SD card
  + Overwrite the old save file when prompted
1. Reinsert your SD card into your console
1. Power on your console
1. Launch "Steel Diver: Sub Wars"
1. Your console will have booted into the Homebrew Launcher
1. Launch nimdsphax from the list of homebrew
1. 如果一切成功的话，你将自动进入 SafeB9SInstaller
  + If your console freezes on a red screen, hold the POWER button until it turns off, then retry this section
