This is a really great read. I was briefly obsessed with laserdiscs in the mid-aughts and went as far as swapping the EFM decoder chip on a Pioneer player with something that could pull the digital audio signal out (details are a little fuzzy at this point). I wanted to figure out a way to extract the video data and it seemed so potentially possible but, as is clear, far from simple and far beyond my abilities at the time. Incredible to see that things have finally progressed to the point where one can fully capture the disc data and emulate these things.
