Yakyuuman (Japan) (V1.1) - Gameboy Color - Sports

One of the four original Game Boy games available for the Japanese launch of that system on April 21, 1989. Released alongside Alleyway, Super Mario Land, and Baseball, it bears the distinction of being the only of the four Japanese Game Boy launch titles never released outside Japan. If there are two copies, two Game Boys and a link cable, two-player mode is possible.
