I have a DSi with ver 1.4.3u and an Acekard pre loaded. My daughter updated the DSi ages ago and when she did the acekard no longer worked. I am trying resolve the issue myself but am a complete novice to the whole process. Can this be fixed?? I am running a Mac if that makes any difference. I went to acekard and downloaded 1.4.4 and AKAIO. Do I need to format the card first and do i need to do anything with the DSi itself?? Much appreciated.
