I was playing china town wars, tried to save my game, and then was presented with a white screen. I reset my DSi, tried again, same white screen about 5 more times. Now when I try to boot the AK2i, it just goes to the black "please refer to your DSi instruction manual" screen. I had the latest firmware. I tried re-applying the firmware, and I get the same thing. I ordered a Supercard One-i.. So no big deal I guess. Just a heads up to everyone else.
