Chōkūkan Night: Pro Yakyū King is a baseball game developed by Genki and published by Imagineer, released only in Japan on December 20, 1996. It plays solo or against another player, and it was followed by a sequel, Chōkūkan Night: Pro Yakyū King 2.

Before you buy

The game came out only in Japan, so the Japanese cartridge is the one to buy. It is among the cheapest Japan-only carts and the fake risk is low. A complete copy costs many times the loose price.
