The "GameAll" portion of the string typically implies a comprehensive "Option File." In the PES community, an Option File is a saved data folder that users copy onto their console via a USB drive. Unlike a full game "mod" which might require a jailbroken console, these files work within the game’s own internal editor. By importing this data, players instantly transform "North London Red" into Arsenal and "Man Blue" into Manchester City, complete with high-resolution jersey textures and accurate 2018-season rosters.
