Hay thar, I'm using a supercard lite on my DS lite, and whenever I close the cover of my DS, I'd get both screens flickering black and white, with the sound suddenly being slow and choppy, and the green LED constantly blinking. Is this supposed to be a sleep mode? also, unrelated: what should I see if my DS lite is flashed? I remember people used to say that I'll not receive the standard health warning menu thing if I have my DS flashed (and thus, can't change brightness settings). But I can do it, and I'm not using passkey/nothing is inserted in my DS slot.
