I bought an EZ Flash 3in1, came to me yesterday and it turns out that every time I save in the game tells me it has been saved, but I turn off and turn on again the Nintento DS and the save is deleted. The only way to save my games is loading it from the microsd the. Sav they believe? be the battery? If so ... because if this happens just bought. NOTE: I just tested with Pokemon Emerald, Pokemon Ruby and sapphire.
