How to Play Bases Loaded 4
Quick start
Choose PLAY at the title with the D-pad and confirm with START or A. Select EXHIBITION, then 1P for a practice match against the computer. Choose both teams with the D-pad and A, then review the lineup before starting. A swings or pitches and B bunts. Fielding uses a center-field layout: Up is home, Left first, Down second and Right third. Move into the ball's path, then throw with the target direction+A. Once comfortable, start REGULAR SEASON and record its passwords.
Controls
Batting: D-pad positions the batter, A swings, Up/Down+A adjusts high/low, B bunts and A cancels the bunt. Running: destination direction+B advances or steals, return direction+A retreats, hold A+B to stop. Bases: Up=home, Left=first, Down=second, Right=third. Pitching: direction+A begins the delivery; tap A during the windup to increase the chosen location's effect, then use the D-pad for breaking pitches. B opens the field view for a pickoff, followed by target direction+A. Fielding: D-pad runs to the ball, B jumps, left/right+B dives, target direction+A throws. START calls time for substitutions; A opens the lineup and B cancels a choice.
Bases Loaded 4 — About this game
Bases Loaded 4 brings back season play while retaining a center-field view of the action. Pick a club from two six-team divisions, chase seventy wins in a season of up to 130 games and then face the other division's winner in a first-to-four championship series. Exhibition matches let you practise against the computer or another player without committing to that campaign. Individual performances also matter: a black-and-white star system reflects strong plays and mistakes, changing how players perform during the game rather than simply replacing their listed statistics. That gives you a reason to watch both the field and the lineup when deciding whether a substitute is needed. A radar helps locate fielders and the ball beyond the main view, while the infield display keeps runners visible. The goal is to build sustained wins through sound pitching, well-timed batting and quick, accurate defense.
