How about uploading some Wii Game Saves.
This is Mario Party 8 game save.
Unzip this file to the SD card in the Wii.
Make this location on the Root of the SD card: private\wii\title\rm8p
save bin file in the RM8P folder
then copy from SD card to Wii using the Wii settings.
I also have Super Mario Galaxy game save if anyone is looking for it.
