Got this DSi and I think it was a store model. Strange thing is It won't ever power off. I have a couple of questions. Can I update the firmware so it acts like a normal DSi? This no powering off thing has to be firmware related right or possibly hardware in the store model? Second question, if I update that firmware to use it normally then can I also use my Acekard2i with it? I've been using the kard with a DS Lite since last year. Haven't updated it at all. Looks like I would have to update to the latest firmware on the kard with it in my DS Lite? Then I could use it in either DS? I really appreciate the help.
