{: .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. 将主机关机
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
