Yes, but why?Your 3ds done crashed is what happened.
I feel like it might have something to do with the system, because sometimes when I open it up after a few days of having it on and not using it, it has a black screen and I have to hold down the power button for like a minute to turn it off. This first happened with Super Mario RPG, so I don't think it has anything to do with Cave Story.
Does it have anything to do with the CIA files?
