Max plugs the Colecovision console into the back of his PC using an RF aerial lead. No such input exists on most modern PC's. He's also able to capture & start copying code through that lead. The RF aerial wasn't designed for that sort of data transmission and even if it was, it wouldn't happen at the speeds shown.
Eugene Wylder claims he used infrared white light to save Reggie. No such thing exists.
