"Can I use an SD Card to save game data on the Wii U system? |
Your first link is accurate as SD cards in WiiU were only for BC and Wii. However, you could connect an external HDD or SSD and save/play games directly from that.
Your second link is referring to game save information from a game you physically own. I own 3DS and 2DS systems and you can buy a digital game, store it on the SD card and play it as such.
It is rather silly to think that these devices won't let you download digitally purchased games to the only extensible storage options they offer and play from those options.
