The demand for "high compressed repack" versions of this game stems from the technical environment of the PSP’s lifespan. The PSP utilized Universal Media Discs (UMDs), which could hold up to 1.8 GB of data. While impressive for the time, this size could be cumbersome for the relatively expensive Memory Stick Duos used for game storage in the early 2000s. Consequently, the "scene"—a community dedicated to game preservation and modification—developed tools to compress these ISO files. By removing unnecessary padding, update files, or lowering the quality of cinematic audio and video, these "repacks" could shrink a game from 1.8 GB to a fraction of that size, sometimes under 500 MB.
