The Indiana Jones machine I played every year at Funspot always had issues when it came to saving high scores.
The machine would sometimes put the 3 man high scores under the seven man scoreboard or totally erase one of the scoreboards, while keeping the other.
Either way whatever scores I achieve were always gone completely upon my subsequent visit, which was usually months later.
Outside of that, certain minor aspects of the audio would not work. (But I don't know if that was related to the score saving problem).
