Games Highly Compressed — Psx

The Sony PlayStation (PSX) popularized 3D gaming in the mid-1990s using CD-ROM media (650-700MB per disc). Decades later, "highly compressed" PSX game packs (often shrinking games to 20-100MB) have become a widespread phenomenon in emulation communities. This paper analyzes the technical methods behind extreme compression ratios (e.g., 10:1 or higher), the distinction between lossless and lossy compression in the context of CD-XA and streaming data, and the trade-offs in audio, video, and disc structure. Finally, it addresses the legal and preservation implications of distributing compressed game ROMs.
