If a game is highly compressed because content was removed (ripped), you may encounter: Crashes during cutscenes that no longer exist.
A file is essentially a standard PS2 ISO image that has been run through a compression algorithm to reduce its file size. Unlike general-purpose compression formats like ZIP or RAR, which require full extraction before use, CSO files are designed for emulators. pcsx2 games highly compressed work
