heres something that happened to me:
i took my memory card with over 400 hours play time and all trophies out to bring over to my friends. i decided i wanted to play a few matches with my bro, so i turn my gc on without my memory card. it says something like " no memory card inserted. continue?". so then i put my memory card in and i though it said " data found on memory card. load data?". ya know? thats what it usually says. but it said " data exists. overwrite?". of course i am an idiot and didnt read it carefully enough and then it went bye bye. then i got everything the next 2 days. i somehow got no damage clear on my first run through all star mode with falco. after i did that, i didnt really care that all my data got erased. it was mostly the stats being erased that i was mad about. just thought you would want to hear a little story.
