Super Mario All Stars - Super Mario World Wii Wad -

For those unfamiliar, a Wii WAD ( Wii Archive Distribution) is a file format used to distribute and play games on the Wii console through the Homebrew Channel. Essentially, it's a package that contains game data, which can be installed and played on a Wii using custom software. In the case of Super Mario All-Stars, the collection was initially released as a retail title, but later became available as a Wii WAD, making it easily accessible to players worldwide.
