Some people have time on their hands, a lot of time. A maker who goes by the handle “LeChuck” has built a 1/6-scale version of the Atari Star Wars Arcade machine and it totally works. Watching Le Chuck play the machine on YouTube is a real kick because I personally put a lot of quarters into the full-size version of this machine at the Boulder, Colorado Chuck-E-Cheese back in the early 1980s. (Yes, and I ate a lot of bad pizza for lunch too.)
