- All PS3 models can play PS1 games natively using built-in software emulation.
- PS2 backward compatibility is limited to early 'Fat' models with full hardware support (CECHAxx, CECHBxx) or hybrid models (CECHCxx, CECHExx).
- Full hardware PS3 models achieve 98-99% PS2 game compatibility, while hybrid models drop to low-mid 90%.
- Later PS3 models (Slim, Super Slim) cannot play PS2 discs at all.
- PS2 games on PS3 face issues like FMV desynchronization, audio drift, and streaming stalls, especially on hybrid models.
- PS3's digital output pipeline alters PS2 graphics, making textures sharper but exposing original analog tricks.
- PS2 memory cards are virtual on PS3, with limited peripheral support (e.g., lightguns fail due to lack of CRT timing).
- Backward compatibility was a launch-era bridge, removed due to cost, heat, and manufacturing constraints.
- Full hardware PS3 models (CECHAxx, CECHBxx) are the best for PS2 games but have high failure rates.
- Hybrid models (CECHCxx, CECHExx) offer better long-term reliability with slightly reduced compatibility.
