i'm in-game and about to save, the game said "unable to save" and i tried different save locations and it still the same. so i had no choice but exit to home. after i rebooted, it shows error " the game card was removed" i thought it was faulty card, but i try another SD and it works. i switched back to the KH sd card, it works but it deleted my save file. is there any way to restore, or can i backup the rest of my saves on PC so this won't happen anymore?
