{: .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 and rename it to `otherapp.bin`
    + Do not add the `.bin` extension if you do not already see it
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
