When Resident Evil Director’s Cut was released, it came with 2 discs: one with the main game on it, whilst the other contained a short demo of Resident Evil 2. When Director’s Cut was released on Playstation Network, the option to switch to the second disc isn’t present, meaning you can’t play the demo. It makes sense because at this point why would you need the demo any more? You can still play RE2 Preview on your PS3, but only by owning the original disc that came with Director’s Cut. Playing it this way reveals that it works on PS3 fairly well, other than some of the sound effects being way off -probably the most noticeable sounds being heard in the inventory screen when selecting items.
