Playing PS3 Games on PS2: Why It's Impossible

Cannot be done. Hardware & software barriers:

• CPU/GPU: PS2 (Emotion Engine + GS) vs PS3 (Cell + RSX) – completely different architectures.
• Disc Format: PS3 = Blu-ray (25/50 GB); PS2 = DVD (4.7/8.5 GB). PS2 drive cannot read Blu-ray.
• OS/API: PS3 games require PS3 firmware libraries absent on PS2.

Backward compatibility only flows forward (PS3 plays *some* PS2 games via software emulation on early models).
