Mizushima Shinji no Dai Koushien — About this game
A baseball game featuring players from ``Dokaben'' and ``Daikoshien.'' Rather than swinging the bat in time with the hit ball, the pitcher decides on the type and course of the pitch, and the batter decides on the strategy, target course, and swing speed, and proceeds with each pitch. In "Daikoshien," you control Meikun High School and fight through the key points of the match according to the story. In ``competitive mode,'' you can choose your favorite team and play against the computer or another player. It is important to look at each player's strong points and pitch types and read what the opponent will choose. POW is required for special actions such as winning pitches and secret hits, and the decision to allocate the increased stock from strikeouts to players also determines the outcome of the match. You can resume the continuation of Dai Koshien by entering a unique password by placing colored balls on the board.
