@_,,,^..^,,,_ : I've had a look at all three versions of Star Wars and yes I was right, the retro release is the one that looks most similar to your screencaps.
@Octorox: There is a blanket green tint over ROTS, its pretty subtle though so i'm not surprised that most don't notice it. Annoyingly it seems that imageshack has deleted all my comparison shots, i'll see whether I have the ROTS ones still lying around on my harddisk still.
