Rally-X to JAMMA Adapter

Description

Rally-X was a fairly popular game developed by Namco in 1980. While the hardware was similar to Pacman, the game uses a unique pinout due to the different power requirements and the addition of button controls. Namco ended up standardizing their pinouts going forward with the release of Galaga in 1981. Midway licenced the game for distribution in North America.
