g-force, I'm running Jedi through v4 now - I think you might have to add a line in the subtitle section to deal specifically with Empire. If you remember a while back when I ran ESB through v4 there was always an error; RotJ and ANH do not return an error, and that seems to be the only section that actually references the episode number, and coincidentally, the line only has specific instructions for a value of episode 4 or 6:
########## subtitle stage
episode==4 ? ANH(last,PAL) : episode==6 ? ROTJ(last,PAL) : Nop()
dark_jedi, do you get an error on Empire? NO biggie, but what do you think?
