SN9047 is set up in Billy's Midway Arcade, recently added as of winter
2019.
It actually belongs to Billy's friend who also has a yellow unit missing some circuit boards. Both machines were bought from a mutual friend who sadly recently passed away and it was decided to put the red machine into Billy's arcade since that way people could play it.
In fact, Gamester81 even visited Billy's Arcade and did a video showing the machine up and running. Click thumbnail to visit.
