Games not working

[kodeblue]

I bought my son an Acekard 2i for Christmas. I have some games I put on the card and everything was fine. I went to add some more games on but cleaned up the titles a bit (removed the numbers that seemed to have been added). After adding more games, I noticed some game icons are pics of the DS instead of a game icon. Also, some other games are not loading. Will changing the titles alter the game to not play some how? Any help on why these probs are happening?

Should really change file names before putting on mem card, the .sav files won't match now, and the mem card as probably gone corrupt now and you will have to re-format and re-install - did you back your card up? if not always best to backup card to pc when it's working
