I got a dsi then got the acekard2i. I have downloaded everything I have seen that I need and it still says "system file missing". I am about to give up what else can I do . I have formatted the sd card and am at a loss...
you need to unzip or unrar what you downloaded. then copy __ak2 (folder) and files akmenu4.nds to the root directory of the micro sd card. moonshell is optional for media player.
