The title screen is not linked to a save file. You could have two games, one with the switch off, and one with it on. Which one should control the title screen? What should happen when the game is launched and the two save files are there but neither value is in memory?
This sort of thing really only works if you only allow a single save slot.
Anyone else find it amusing that people watch videos of tragedy and then try to take the "moral high ground" by having sympathy for the victims? Dude, you watched the tragedy for the same reason everyone else. People being injured is an instinctive human curiosity.
