Short answer: OPL does not run on PS3, so it can't be used to load PS2 ISO games on a PS3. Whether a PS3 can play PS2 content at all depends entirely on which specific model you have — here's the accurate breakdown.
The Original PS3 Had Real PS2 Backward Compatibility
Only four PS3 model families ever supported PS2 discs: CECHA, CECHB, CECHC, and CECHE. Sony removed the feature entirely from every model released afterward, including all Slim and Super Slim consoles.
| Model | Region / Example | How It Runs PS2 Games | Compatibility |
|---|---|---|---|
| CECHA | Japan launch (e.g. CECHA00) | Full hardware — real Emotion Engine + Graphics Synthesizer chips | ~98-99% |
| CECHB | North America launch (e.g. CECHB01) | Full hardware — real Emotion Engine + Graphics Synthesizer chips | ~98-99% |
| CECHC | PAL/Europe 60GB (e.g. CECHC01) | Hybrid — Graphics Synthesizer chip kept, Emotion Engine (CPU) emulated in software | Lower, game-dependent |
| CECHE | North America 80GB, 2007 (e.g. CECHE01) | Hybrid — same approach as CECHC | Lower, game-dependent |
CECHA and CECHB units contain the actual PS2 chipset, so a PS2 disc runs on real PS2 hardware sitting inside the PS3 — compatibility is close to a real PS2. CECHC and CECHE kept only the graphics chip and emulate the CPU in software on the PS3's Cell processor, which is good but not identical to native hardware, so a small number of games have quirks. Every PS3 released after these four families — every Slim and Super Slim model — has no PS2 compatibility whatsoever.
What About PS2 ISO Files Specifically (Not Original Discs)?
Native PS3 backward compatibility, where it exists, is built around reading the original physical PS2 disc — it isn't a general-purpose PS2 ISO loader the way OPL is for PS2 hardware. Loading PS2 ISO files on a PS3 falls outside official Sony functionality entirely; within the PS3 homebrew scene there are separate tools built for jailbroken ("CFW") consoles that use PS3's own software PS2 emulation layer, but that's a distinct ecosystem from OPL, requires modifying the PS3's firmware, and has its own compatibility limitations — it isn't something this guide walks through.
