Hello, I seem to be having a problem with my DS Phat (obviously). Whenever I try to boot it, it won't boot! I've tried charging the battery but the charging light won't switch on. Before this problem occurred, my Phat was fully charged and everything was working. But then a few days ago, peculiar things started to happen. Firstly, my DS firmware completely rebooted and when I switched it on, it prompted me for reconfiguration. Secondly, it started to spontaneously switch off whilst playing a game. Thirdly, whenever I tried to reboot it, the light would turn on, and then switch off again. I had to hold the button (to jumpstart it) just to get it to turn on. But yesterday, it just gave up and stopped working. Could the problem be with my flashcart (EZ-Flash V) or has by 'rechargeable' battery gone flat? Help would be really appreciated.
