Back when game stores still had the 3DS with demo games on display, the games would run off a special "Not For Resale" demo cart that Nintendo distributed to the stores. The carts were programmed so that when a 3DS boots up, it would automatically skip the Home Menu and run the demo, while disabling the Home Button in order to lock the console into demo mode only. This was designed to prevent customers from accessing the other system applications and potentially changing important system settings. The carts looked a bit like this: Now the question is, if someone were to use something like Decrypt9 to extract the contents off one of these cartridges as a .cia file and then install it to a 3DS running a CFW, would that make the console permanently stuck in the demo mode every time it boots up? The store display units could be returned to normal mode simply by ejecting the cartridge but since a .cia is installed to the system's memory and is persistent on the Home Menu, that would not be possible. Just a question out of pure curiosity.
