Description
Alpha Denshi, later renamed to ADK Corporation was an arcade game manufacturer mainly known for their Neo-Geo releases. In the 1980s however, Alpha Denshi released a number of arcade titles on their own platform. There was a mix of games that ran on unique hardware with different pinouts, and also some that ran on a common hardware platform with the same pinout. These games can be easily identified by the additional 12 pin video edge connector on the video board. This adapter converts only the Alpha Denshi games with this connector.
