How can I tell if my PS3 is backwards compatible?
All backwards compatible PS3s are "fat," but not all fat PS3s are backwards compatible. If you have a fat PS3, check the number of USB ports on the front of the PS3. If the PS3 has four USB ports, it is backwards compatible. If it has two USB ports, it cannot play PS2 discs.Which PS3 models are backwards compatible?
