I actually have already tried with TN1’s. Some of the stars are salvageable, but I haven’t had much luck getting it to look anywhere near decent. What I’ve been trying with laserdisc transfers looks worlds better.
And actually, you would think you could just plop in Empire’s starfield, but while you can clearly see it is the same starfield is used by matching up certain star formations, it is shifted to the right dramatically. So much so that much of the 81 ANH starfield actually isn’t visible at any point in Empire, because it’s been cropped at the sides or something. It’s really strange and I don’t know why they would have made a starfield that overly wide.
