The use of WAD files streamlined the process of game distribution on the Wii. Before digital distribution became the norm, games were typically sold on physical media such as DVDs or cartridges. The WAD file format allowed Nintendo to easily distribute games digitally through the Wii Shop Channel, making it convenient for consumers to purchase and download games directly to their consoles. For Super Mario Galaxy 2, being a popular title, its distribution via WAD file ensured that it could be efficiently downloaded and installed by users worldwide.

In the context of the Nintendo Wii console, a .wad file (WAD) is an archive format used to store channel data, IOS (Internal Operating Systems), or DLC. They act similarly to a ZIP archive, packing game files, icons, and banner data into a convenient, installable package.
Later in the Wii U lifecycle, Nintendo released select digital Wii titles on the Wii U eShop. Enthusiasts use modding tools to package the Super Mario Galaxy 2 ISO into a specialized WAD or encrypted installation format. This allows the game to be installed directly onto a hacked Wii U home menu, enabling native widescreen execution and gamepad compatibility. 2. Custom Homebrew Forwarders
