So I've been playing a level on one of my games and I saved multiple times, sometimes overwriting my saved data because I wasn't sure how much of my SD card I had used. Anyways I finally beat the level today an save after that. I then messed around with my SD card trying to get .ds ROMS to work forgetting that I needed another microSD to play them. When I went back to my game all my recent saves from the past day or two were gone. Did I use up my memory? I'm afraid to check because I heard you can't go into data management for some reason without jeapardizing your system. The only SD card reader I can use is a spare laptop that I hate because it's bugged with a million freaking viruses which make it run at 90% CPU so it makes it a long and annoying task to use it. Like I said my last save was an overwrite a few hours ago. What deleted all my saves? Do I need to do something after I save like close the game properly? I can't remember if I just hit the home button then removed my memory card or not? What do you guys think happened?
