That's so clever! I would have guessed that film reels would be too fragile for that sort of continuous usage, though I'll confess that I have no personal experience with them.

I was really curious about how they would handle 'rewinding' a film reel between plays; assuming 16mm film, I figured, it would have been about 30 meters of film, so I wondered whether you could splice it together into a full loop and concertina it inside the cabinet so that it doesn't actually require rewinding between plays, and can instead just keep playing it continuously in a forward direction, and... after a bunch of Internet trawling, I found a forum post by somebody who had purchased and restored two units, that's exactly what they'd done! (I had my calculations about the length of the film wrong, though; apparently the full film is only about 10 meters long, which would definitely make it easier to wrangle the loop!)

The world of these older electromechanical arcade games is seriously cool; so much history and ingenuity here that I hadn't been aware of!
