Champion Baseball to JAMMA Adapter

Description

Allows you to use your Champion Baseball pre-JAMMA game, in a JAMMA cabinet or a super gun device.

Champion Baseball was originally developed by Alpha Denshi, and was released and distributed worldwide by Sega for the arcade market.

This is yet another game released by Sega with a unique pinout, likely the result of not being developed in house by Sega themselves.
