OK, I am probably a clueless noob, but HTF do you get a Supercard to save yer gosh-darn games and game data? The save-file doesn't exist for no reason!! It saves, but, once I turn off the GBA, all the save data is lost. for example, if I am playing Sim City, and I save a city...that city stays, as long as the power is on. I can load and re-load it as many times as I want. but, if I turn off the GBA, the save data goes away. WTF?
