Yes, Nintendo Power is no more. Though unless you are Japanese the chances are that you will not exactly be overcome with grief. Nintendo Power was a kind of Virtual Console download service for Super Famicom and Game Boy. Gamers could download games onto flash RAM carts from shop download kiosks. And there have been some classics, including Super Mario World and Donkey Kong Country 1, 2 and 3. The download kiosks are now being pulled though, so the service is no more.
