Compression strips this dead weight, sometimes shrinking a file by over 90% without losing any game data. Top Compression Formats for PS2

While text and certain digital assets compress incredibly well, complex 3D game geometry, pre-rendered video cutscenes, and high-fidelity audio files physically cannot be compressed from 4 GB down to 10 MB using lossless algorithms.
