I was playing Pokemon Pearl about half an hour ago...suddenly, and randomly, it just cut out. Made the sound it makes when you turn it on/off, like, the sort of pop of the speakers. Everything stopped moving, and I couldn't do anything, so I turned it off and on and....now it just doesn't work. Goes to the "touch screen to continue" message and then shows the DS slot as empty. Turned it on/off like 20 times, tried to take it out/in a load of times...nothing. I checked the memory card in my computer and everything seems to be fine, so I don't think it's a problem with the memory card. Tried using other games and they work fine, so I don't think it's a problem with the DS so... is my R4 dead?
