Title: Feasibility and Limitations of Highly Compressed PlayStation 2 Games on Android Devices
Abstract
The demand for PlayStation 2 (PS2) emulation on Android devices has grown significantly, leading to interest in "highly compressed" game file formats. This paper analyzes the technical feasibility of such compression, the performance implications for mobile hardware, and the legal status of compressed game distribution. Findings indicate that while advanced compression algorithms can reduce file sizes by 30–50%, the decompression overhead typically harms emulation performance on current Android SoCs. Moreover, most "highly compressed" distributions violate copyright law.
5. Legal and Ethical Considerations
Distributing or downloading “highly compressed PS2 games” typically infringes copyright, unless:
Hot Shots Tennis: ~146MB – A cartoon-style sports game that is very easy to run on low-end devices.
Part 4: The Best File Format for Compression – CHD
If you are compressing your own games, avoid ZIP or RAR. The gold standard is CHD (Compressed Hunks of Data) .
The PlayStation 2 library consists of over 4,000 titles, many of which are "bloated" with dummy data—empty space on the physical DVD used to ensure the disc spun correctly or to fill the outer edges for faster reading. For Android users with limited internal storage or small microSD cards, "high compression" is the only practical way to maintain a diverse library. 2. Popular Highly Compressed Formats
