The term "ISO" refers to a disc image file—the digital clone of a UMD (Universal Media Disc). The PSP scene, kept alive by a devoted homebrew community, thrives on ISOs. But a FIFA 15 ISO would require a source UMD to rip, and since no such UMD exists, the search is for a holy grail. The word "exclusive" adds another layer of delusion. Why would a game that was never released be exclusive? The answer lies in the nature of modding. A handful of dedicated fans have created "patch ISOs"—taking the FIFA 14 engine and painstakingly updating the kits, rosters, and menus to reflect the 2014-2015 season. These fan-made FIFA 15 modifications are, in a sense, PSP exclusives: they exist only on that hardware, a loving tribute to a platform abandoned by its creators.
