This method of using Seedminer for further exploitation uses your movable.sed file to write a custom save file for Steel Diver: Sub Wars, which can then be used to launch the Homebrew Launcher.

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.

你需要准备点啥？

  • The game “Steel Diver: Sub Wars” installed on your console
    • If you have downloaded it before, you can redownload it
    • Your SD card must be inserted in your console to install Steel Diver: Sub Wars
  • Your movable.sed file from completing Seedminer
  • The latest release of Steelhax (direct download)
  • The latest release of SafeB9SInstaller (direct download)
  • The latest release of boot9strap (direct download)
  • The latest release of nimdsphax (direct download)
  • The latest release of Luma3DS (the Luma3DS .zip file)
  • The latest release of HBL otherapps (direct download)

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
  2. 将你的 SD 卡插入到电脑
  3. 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
  4. 在 SD 卡根目录创建一个名为 boot9strap 的文件夹
  5. 从boot9strap .zip 文件中复制 boot9strap.firm 和 boot9strap.firm.sha 到你SD卡的 /boot9strap/ 文件夹中
  6. 从 SafeB9SInstaller .zip 压缩包中复制 SafeB9SInstaller.bin 到 SD 卡根目录下
  7. Copy the steelhax folder from the Steelhax-release.zip to the root of your SD card
  8. 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
  9. 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
  10. Copy the nimdsphax folder from the nimdsphax .zip to the /3ds/ folder on your SD card
  11. Reinsert your SD card into your console
  12. 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
  2. Exit “Steel Diver: Sub Wars”
  3. Power off your console
  4. 将你的 SD 卡插入到电脑
  5. Open the SteelHax Save Tool website on your computer
  6. Select your movable.sed file
  7. Select your region based on your console
  8. Select “Build and Download”
  9. Wait for the process to complete
  10. 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
  11. Copy the newly downloaded 00000001.sav file to the data folder on your SD card
    • Overwrite the old save file when prompted
  12. Reinsert your SD card into your console
  13. Power on your console
  14. Launch “Steel Diver: Sub Wars”
  15. Your console will have booted into the Homebrew Launcher
  16. Launch nimdsphax from the list of homebrew
  17. 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

第三步 – 安装 boot9strap

In this section, you will install custom firmware onto your console.

  1. When prompted, input the key combo given on the top screen to install boot9strap
  2. Once it is complete, press (A) to reboot your console
  3. Your console should have booted into the Luma3DS configuration menu
    • Luma3DS 配置菜单用于设置 Luma3DS 自制固件的可选功能 其中有许多功能可用于个性化或调试
    • For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
    • If your console shuts down when you try to power it on, ensure that you have copied boot.firm from the Luma3DS .zip to the root of your SD card
  4. 按下 “Start” 键保存设置并重启

At this point, your console will boot to Luma3DS by default.

  • 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 install useful homebrew applications to complete your setup.
