I have the ds fire card and have mario kart ds on it but i want to use a someone else save,i have one save in .sav format but when i replace my current one with the other persons one, and start up the game it just starts a new save instead of loading the save that of the other person.
hmm... i've never tried this myself, so i dont know if using other peoples saves works.....it 'might'!? . try this... what was the last game you played before replacing the 'sav file'..was it mario kart? . go into the DSYSTEM folder in your firecard....delete the file that says 'last save'(this will delete the last save file created) then replace the MK sav file. then try. . i'm only guessing here, mate. hope it works for you.
