I have seemed to run into a problem. All I want to do is transfer ONE game over. (Mario 64 so I can play it in wii U mode) but whenever I try to prep my SD card it says "An error occurred while accessing the wii systems memory) I deleted all my save data and channels that were not legit but it's still doing it. Does anyone know a work around for this? I looked all over the internet and can't find a solution either. Please help.
