The problem may be something in the ds cartridge slot. Try removing the game, blowing into the slot, then re-inserting the game. If that does not work, you may need to buy a new copy of the game. If you don't want to lose your progress you can buy a GBA/DS Action Replay and use it to backup your save data. that is a Gameboy Advance action replay with a nintendo ds slot. you can find it at www.codejunkies.com or you can look around for it at local stores or on ebay.

Is your system connected to the net? if you download the update that may work for you. If not i know that SSBB ( super smash bro brawl ) is a dual-layered disc, the first one out for the wii system, and that it is alot more difficult to read for the little lense in the system. Call nintendo and see if you can set up a repair for both your system and SSBB.

It's likely one of three things. Either your ribbon cable that connects the LCD to the board has come loose from it's connector, it has broken, or the LCD has gone out. These are the most common. Depending on which it is will depend on the steps you'll need to take to replace it. However if you got it for Christmas and it was new it is under warrenty and you can contact Nintendo for a free replacement DS.
