3DS:Alternate Exploits/Homebrew Launcher (steelhax)

Required Reading

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 with unSAFE_MODE to run SafeB9SInstaller.

If you already have Steel Diver: Sub Wars, this process will overwrite your game's save file!
