So I've been using my Acekard 2.1 all week with no problems, until I used it in another DS today. I had been playing a game using a DS Lite with no problems, then today I used the Acekard in an original DS to play a different game. Once I went to go play the game back in the DS Lite, I loaded the game I had been playing all week and it couldn't find the save file. What happened here? Did the original DS cause the Acekard to erase my saved game? There are other save files still in tact, but for whatever reason switching DS's seems to have screwed things up a bit. Is there any way to recover my save file I was using? EDIT: So it appears that my Chrono Trigger saved game got erased (after 11 hours of play)... My GTA save is fully intact and works great. What the hell, if I lost 11 hours of gameplay for no good reason I will not be happy.
