The Nintendo DS unit is working fine with regular game cartridges. Only a white screen, when using EZ Flash IV with 1gbmicro card. Worked fine 'til unit was dropped. Oopps!!!!! Using the EZ Flash in a different unit, it fails again, but sliding the 1gb micro card into another EZ Flash IV, all but one of the games is playable. The one game that fails is Animal Crossing, and was the game being played when the DS was dropped. Help please. Do i need a new Flash????
