When it goes to the gray screen with the power off option when you FIRST press the power button. And it does this with cartridges, digital downloads, anything for an original DS, anything 3ds and above work fine.
I have a New 2DS XL, and before it loaded DS games just fine, but one day every time I try to load one, the screen flashes to a white screen with a black border, then goes to the power save menu. What do I do?
