True, but it looks for me like a tool that can generate a „nice“ path for every game. The path is true for every instance of the same game. If the path is done once, everyone can benefit from it. So a patch would not bundle copyrighted material, only the changes made from your tool that anyone else would end up with anyway. It is just a convenience thing. One would need the path, not running your tool over and over again for everyone wanting to play the sane version of the game.
