Ok, I had heard before (dunno if it's true or not) that even when you close your DS and the screens go black and the sound cuts off, the DS doesn't entirely go into sleep mode. In fact, what I heard is that the battery drains just as much as if the DS was on. Is this true, or perhaps was it true in an old version of Sakura or even TouchPod? And is it still true to this day? Someone please clarify.
