Technical Details (optional)

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.
