Well, I don't have SoulSilver, but I'm at the moment backing up my collection of originals. And while backing up the save from Zelda Phantom Hourglass the program said something about an EEPROM error. The savefile was transfered to my computer, but when I inserted the game into my DS it gave me an "your savefile is corrupt" and then "fixing save file" message. It somehow managed to repair the saves, because they are still there and working. Weird nonetheless.
