Today I was walking in my college campus and my DS with my R4 fell and hit the pavement. It fell flat and didnt bounce or anything. it got scuffed a little but it wasn't broken. Later on I tested it out, and for some reason, every game worked except for my Animal Crossing. When I load it, it just immediately freezes and the screen stays on the rom selection screen. I tried formatting, renaming the rom, downloading and replacing the rom itself, i even took my save off and made a new file, but it all ends up with the same freezing. It worked perfectly, even just last night, up until i dropped it. it's kinda a weird thing to have happen after a ds being dropped. Any advice?
