How to Play Nantettatte!! Baseball
Quick start
First, learn the operations by playing 30 games or matches. For pitching, use the cross button to determine the course and use A, and for hitting, align the position and swing with A. B is used for auxiliary operations for each situation, such as pitch type, advancing to base, and returning to base. In defense, move the fielder toward the ball, and after catching the ball, throw the ball using direction and A. During the season, we look at the pitcher's wear and tear and make early decisions about pitching.
Controls
Cross button: Operate menus, pitching courses, batters, fielders, and runners. A: Decision, pitch, swing, basic throw. B: Assistance with cancellations, pitch changes, advancing/returning bases, etc. START: Game start, time.
Nantettatte!! Baseball — About this game
"Nantatta!! Baseball" is a baseball game where you can choose from multiple season settings, ranging from short-term to 130 games, and aim to win the Japan Series. In addition to the regular teams, there are also special teams, which combine pitcher changes, pinch hitters, defensive positions, and other arrangements with actual pitching and batting operations. When pitching, I spread out the course and speed of the ball, and when hitting, I look at the trajectory of the ball and adjust the timing. In a long season, it is important to consider not only one game, but also the condition of the players and pitcher selection, and to avoid unreasonable base advances and maintain a stable game flow.
