Free Play, Attract Sounds, and Permanent High Scores
Free Play allows Juno First to start without inserting coins while retaining traditional Coin-Up operation as an available setting.

Attract sounds are enabled during every attract rotation, and screen saver attract mode helps reduce CRT monitor burn-in during idle operation.
