The desire to store large numbers of games on limited storage media—such as older portable hard drives, flash drives, or retro emulation handhelds—has driven interest in highly compressed PS2 disc images. While a standard PS2 game ISO can occupy several gigabytes, advanced compression techniques can shrink certain titles by 80-90%, making them viable for low-capacity devices. Achieving a sub-500MB size is not a universal standard but a targeted optimization reserved for games with specific technical characteristics.
Games with extensive open worlds, full orchestral soundtracks, or hours of voice-acted dialogue (e.g., Grand Theft Auto: San Andreas or Final Fantasy X ) are virtually impossible to compress under 500MB without destroying core functionality.
The Sony PlayStation 2 (PS2), one of the best-selling video game consoles in history, possesses a vast library exceeding 3,800 titles. Standard DVD-ROM capacity for PS2 games ranges from 4.7GB (single-layer) to 8.5GB (dual-layer). However, a niche but active community of data compression enthusiasts has successfully reduced many of these games to file sizes under 500 megabytes (MB). This paper explores the technical methodologies behind this extreme compression, the genres most amenable to such reduction, the inherent trade-offs in quality and functionality, and provides a curated list of notable titles available in this compact format.

While compressing games one lawfully owns for personal backup may fall under fair use in some jurisdictions, downloading pre-compressed ROMs or ISOs from the internet is generally copyright infringement. The PS2 remains a commercially protected system, and publishers still hold rights to these titles.
