This is a major, beneficial malfunction. One or more players gained a significant advantage. I probably would have ruled player one keeps their score if a new game were played on TRON. Unless the machine were repaired it’s better to switch games to avoid the problem.
“Any beneficial malfunction which provides one or more players with a significant scoring or strategic advantage in a way that is not part of normal gameplay will void the score of the affected player(s), unless all immediately-affected players and tournament officials can agree on a suitable adjustment of the score or other elimination of the advantage.”
