The phrase points to the action of acquiring a digital copy of the game New Super Mario Bros. Wii in a format suitable for use with a Wii emulator or potentially, though illicitly, on a modified Wii console. This typically involves obtaining a file, often in ISO format, containing the game’s data. Such files are usually found on the internet through various download sites or peer-to-peer networks.
The availability of these downloadable files allows individuals to experience classic games without owning the original physical media or console. It provides access to titles that may be out of production or difficult to find. However, downloading and distributing such files without authorization from the copyright holder is generally illegal and carries potential risks, including malware infection and legal repercussions.
