Apparently Moon Patrol operates differently than most other arcade games with the dip switches. With most games, at least the ones that I tested, the dip switch settings are not updated/refreshed while a game is active. Unfortunately with Moon Patrol, dip switches are updated and immediately take affect while the current game is running. On top of that, MAME doesn't update the .cfg file while the game is running, so unfortunately, we have zero visibility to that. Sadly this means that tracking dip switch changes (for Moon Patrol specifically) is impossible.
