The PlayStation 3 introduced a significant layer of backward compatibility to the PlayStation brand, allowing a vast library of PS2 games to be played directly on the new hardware. This feature was a major selling point for consumers transitioning from the older console generation, providing immediate access to a familiar catalog of titles without the need to maintain multiple systems. Understanding which PS2 games are fully compatible on the PS3 is essential for collectors and players who value a complete gaming experience.
Technical Foundations of Backward Compatibility
Unlike the PlayStation 2, which could play original PlayStation (PS1) discs, the PS3’s ability to run PS2 software is not based on simple data reading. The PS3 contains a physical Emotion Engine processor, the same core chip found in the PS2, which handles the specific demands of these older titles. This hardware-based solution ensures that games run at their native resolution and framerate, rather than relying on software emulation that often compromises performance. The integration of this chip allows the PS3 to essentially run a secondary console within its own hardware architecture.
Identifying Compatible Titles
Not every PS2 game benefits from this hardware integration, as functionality depends on the specific model of the PS3. Early "fat" models, specifically those with the CECHAx, CECHBx, or CECHCx serial number prefixes, included the Emotion Engine and supported the full suite of PS2 features. Slim models, however, generally omitted this chip, restricting them to a list of games that rely solely on software emulation. Checking the model number of your PS3 is the first step in determining the scope of your backward compatibility.
Model Specific Limitations
For users of the slimline PS3 models, the library of playable games is significantly reduced. These units lack the internal hardware required for full-speed PS2 playback, meaning only a select few titles are able to function, often at reduced graphical fidelity or stability. Owners of these models are generally restricted to the "PS2 Classics" available on the PlayStation Network, which are titles specifically patched to run through software emulation rather than relying on the physical disc and hardware chip.
Performance and Visual Fidelity
When played on a compatible "fat" PS3, most PS2 games operate exactly as they did on the original hardware. There is no upscaling applied by the PS3 itself, so the output remains locked at the native 480i resolution standard of the PS2 era. While this results in a distinctly retro look, it preserves the authentic visual style the developers intended. Some users appreciate this raw, pixelated aesthetic, as upscaling can sometimes introduce unwanted visual artifacts that deviate from the original presentation.
Controller and Functionality
The PS3 controller, the Sixaxis, can be used to play PS2 games, but the experience varies significantly depending on the title. Games originally designed for the DualShock 2 will feel more natural with the Sixaxis due to similar button layouts and analog stick sensitivity. However, titles that specifically required the pressure-sensitive triggers of the DualShock 2 might feel slightly different on the Sixaxis, and the lack of rumble feedback on the Sixaxis can remove a layer of immersion for certain players.
The Library of Classics
Despite the hardware limitations of slim models, the library of PS2 games on the original PS3 remains impressive for backward compatibility. Iconic series and genre-defining titles are available, allowing players to revisit sprawling RPGs and competitive sports titles. The following list highlights some of the most notable PS2 games that maintain full functionality on compatible PS3 hardware.
Grand Theft Auto: San Andreas
Final Fantasy X-2
Kingdom Hearts II
Devil May Cry 3: Dante's Awakening
Shadow of the Colossus
Ratchet & Clank: Going Commando
Tekken 5
