How to Play Best Play Pro Yakyuu
Quick start
Press START on the title and select the open match first to check the flow of the match. Decide on the matchup card and team, organize the starting pitcher, batting order, defensive position, and start the game. This is not a game in which players directly control pitching and batting, but as a manager, you instruct strategies, pinch-hitting/pinch-running, pitching changes, and fielding changes according to the situation. The goal is to exceed the score at the end of the 9th inning. Once you are familiar with the operation, please proceed to the 2002 opening data pennant, edit player names and abilities, and create your own original team.
Controls
Use the cross button to move the cursor between the menu, players, batting order, and strategy. Press A to confirm/proceed to the next step, press B to cancel/return to the previous screen. During a match, open the strategy display, use the cross button to select attack/defense signs and substitution items written on the screen, and press A to indicate them. START opens the match progress menu or pause. There are no buttons to directly control batting, pitching, and defense as a player.
