[Matt] has managed to cram a Wii into an old NES. The write up is fairly short, but does mention a few details. He installed some Game Cube controller ports and a Game Cube memory card. He’s added some external LEDs connected to the Wii’s power button. He put a lot of effort into this, as he said almost every area of the internal case needed some serious dremel action to make the Wii fit inside. He’s even promised a more detailed write up, so keep an eye out for that.
