The only videogame my dad has ever gotten into (other than Pong) was NFS II SE. He wouldn’t race, he just liked driving around at 35 MPH and looking at the scenery. He enjoyed this so much he bought a wheel and pedals for it. I loved this game as a kid, and the fact that I could play it with a wheel. The song “Headless Horse” off the soundtrack is pure 90s cool as well.
Gozz is correct. You’re misunderstanding the nature of a digital signal. What the author did was convert a digital signal to an analog signal, store that analog signal on a bird, then record that analog signal. Whether it was redigitized after the fact is irrelevant. It is not a digital process end-to-end. This is the same as if I were to download a YouTube video, record that video on a VHS tape, then redigitize that video. Not only would the end result not be a bit for bit match, it wouldn’t be a match at all despite containing some of the same visual information, because it would be the product of a digital-analog-digital conversion.
