IM BACK!!
Now, did you drop the ds or something that might damage it? If You Got The Game new from a store, its not the game, they are hard to break. If you got the game off Ebay(2 of my games are new from ebay and they freeze up often so I have to save alot so I don't lose my data), it might have been already damaged or might just be a hacked game. Ebay is bad(From My Experience), even though its cheaper. Anyway, I doubt its the game. As Kingdra was saying, each time you charge the ds down and back up, it loses a little power. So If you charged it 1000's of times, then you know why its broken, the battery cant be charged anymore. So Try Getting a New Battery for your ds(I think Gamestop and EB Games sell them), and that might fix it. If you dropped HG alot or did anything to damage it, it, that might be the problem too. If your other games don't work, either, then somethings wrong with your ds!:( Sorry and Hope This Helps!:)
