SNK Rockola to JAMMA Adapter

Description

Allows you to use your SNK / Rockola classic pre-JAMMA game, in a JAMMA cabinet or a super gun device.

SNK (Shin Nihon Kikaku) is a Japanese video game manufacturer best known for its Neo Geo platform and games.

During the early days of arcade game production, many of its games ended up being licensed to Rockola for distribution in the United States. As a result many of the more popular Rockola games used a very similar, SNK developed hardware and a common pinout.

While this pinout has been used by SNK for their early games, later on the company released another common hardware platform with a different pinout.
