The phrase refers to acquiring a disk image file, in ISO format, of the video game Super Smash Bros. Melee. This specific file type is a sector-by-sector copy of the original game disc, intended for use with an emulator or, in some cases, for creating a backup copy. The term combines the title of a popular fighting game with the method of obtaining its digital representation.
Accessing this game’s ISO file became prominent due to the game’s enduring popularity within competitive gaming communities and its limited availability on modern platforms. Emulation allows players to experience the game on devices other than the original Nintendo GameCube console. However, it is important to note that distributing or downloading copyrighted games without owning the original is a violation of copyright law in many jurisdictions.
