This week in the Nintendo Download: The Cave, Brain Training, and an anniversary party

Nintendo leaves its last-generation systems behind this week — with no new content coming to the original Wii or the DSi — but at least you will soon be able to play your Nintendo Entertainment System and Super Nintendo Virtual Console purchases on the Wii U’s fancy tablet controller. At this point, Wii and DSi owners should probably just take what they can get (which, odds are, will be an old SNK game or something that is barely a game at all).
