Hello, I've been using Wiimmfi for a while an I really like it, also I would like to help. I have seen that Mario Sports Mix is not supported yet so I have this savegame from Mario Sports Mix I used with Nintendo WFC. And I have uploaded it to 4Shared (the link is below), it was extracted with SaveGame Manager. It has 3 files (includes the banner) The friend code string is: 2581 4173 9295. I really hope this helps. *censored* I hope this game can be supported by Wiimmfi soon.
