Which PS3 Models Play PS2 Games? All of Them—With Major Caveats

Every PS3 Has Some Backward Compatibility

All PS3 models (Fat, Slim, Super Slim) can play some PS2 games via software emulation, but the experience varies wildly.

Model	PS2 BC Method	Compatibility
Launch "Fat" (CECHA/B/C/E – 20/60/80GB)	Hardware (Emotion Engine + GS chip)	~98% – near native
Later Fat (CECHG/H/K – 40/80GB)	Software (partial EE/GS emulation)	~70% – many glitches
All Slim / Super Slim	Software only	~70% – same as late Fat

PCSX2 (PC): Near-perfect compatibility, upscaling, widescreen patches.
PS2 Classics on PS3 Store: Re-purchased, per-title optimized (delisted but still downloadable if owned).
Original PS2 + FreeMCBoot + OPL: Play ISOs from HDD/USB/SMB—best authenticity.

If you have a launch Fat PS3 with four USB ports, you own the best native experience.
