Mario Kart 7 has updated my sons 3ds and it is now on fw 2.2.0-0U. Ive checked the site and I cant find an old update to use to update my acekard. Can someone direct me to a link with the old AK update or give me some advise on what to do. Ive seen the latest offical fw doesnt work with the AK2 so I cant update to that. Any help would be appreciated.
