Last night was working ok, this morning, i've turned it on (ds lite+g6 real) and there were no games or saves on the card. Nothing! The NDS folder was empty. I reformat the card (through the ds) and copied back all my games and is working, for the moment. My luck was i didn't have any important saves on the card (just 2-3 saves, from some games that i've just started). But what if it will happen again, and this time i will lose a save from the middle (or end) of a hard game (say Contra 4 )? I think i will go berserk if that happens. So....Why this happend? Is my card faulty?? How i can prevent this in the future? I paid for my G6 1gb real some 60$, so it's not cheap.
