I have an issue with my EZ Flash IV I've been unable to find a solution to. Whenever a save file is created and stored to the SD card, it's an empty file containing 0 kb of data. This what the save folder looks like in Window's file explorer: I know that the battery isn't faulty, since a save of a game remains as long as I don't play another game. I'm also confident it isn't the memory cards, as I've tried using more than one. Do you think my EZ Flash IV might be defect, or could there be another explanation?
