When you buy a Wii game on the eShop, it downloads to the Wii U memory. But does it also save there, or does it save to the Wii Mode memory like a disc-based Wii game would? I'm asking because I want to be able to move my save games to the SD card so I can continue a Skyward Sword game on a Wii after starting it on my Wii U with the eShop version.
