The other day when my wii stopped working i called the nintendo customer support. I asked them if there was any way to save my memory so i would keep all my smash achievements. He then asked if i have ever thought about investing in a sd card to back up my files. So i guess according to this nintendo customer service rep you can save smash to a sd card. Not sure how true this is though. Unfortunately my wii wouldn't even turn on for me to save my files, so it looks like im gonna play everything over. At least that game is insanely amazing.
