Dating myself but does anyone else remember being able to take a speaker magnet and rubbing it on the side of 80s arcade games and getting unlimited free credits? From time I was in like 4th grade through 8th grade I recall using this trick to play games. I don’t recall if the arcade manufacturers figured out the trick and changed the design or if the prevalence of home gaming led to the end of this by early 90s. Anyone else remember this???
