This game is a modified version of the Atari 2600 edition of RealSports Baseball. The controls remain exactly the same. The changes include updated graphics and color schemes. Additionally, the number of options has been limited to one or two players, and in single-player mode, you can choose whether the human player bats first or not. Everything else stays consistent. You can still pitch fastballs, curveballs, sinkers, and more, and you can still bunt, hit fly balls, and so on. Scoring works the same way, with games going into extra innings if tied after nine. The difficulty switches have no effect.
