WAD files are Nintendo Wii VC, or Virtual Console, games. These WAD games are installed on your Nintendo Wii main menu when you purchase them from the Nintendo Network over Wi-Fi on your Wii. The games can be from a range of different gaming systems including Atari, Sega Genesis, Super Nintendo, and even Nintedno 64 games. You can move these WAD games onto an SD card inserted into your Wii and transfer them between Wii systems. If there's a need to play an NTSC WAD on a PAL Nintendo Wii, you can use Freethewads software to convert your NTSC WAD to a PAL WAD.
