when i copy and paste my game files (nds and .sav) to my computer and then copy and paste them to another card it seems the saved information is not transfering. I have renamed all the games in my computer by eliminating the number prefix so they are alphabitized would that effect the sav files. I changed teh name after first unzipping the files, wouldnt the sav file rename also before the game has been put into the ds. please help i keep losing my place in games
