Janputer (ジャンピュータ), published by Sanritsu Giken Corp, was one of the earliest arcade Mahjong titles and helped Alpha to establish themselves in the industry.

That same year, Craul Denshi released Alpha's Crush Roller (Make Trax),[2] a maze game similar to Pac-Man.

[1][4] The 1990 Neo Geo arcade launch lineup included two Alpha titles: Magician Lord and Ninja Combat.

In 1992, following the revitalization of the fighting game genre by Capcom's Street Fighter II, Alpha developed World Heroes with assistance from SNK.

In the late 1990s, newer fifth generation consoles with 3D graphics and CD audio were becoming more popular with consumers and an attractive target for video game developers.

Still under exclusive contract, ADK was only allowed to develop two Sega Saturn ports: World Heroes Perfect and Twinkle Star Sprites, both published by SNK.

ADK developed only eight titles for the platform which was dwarfed in sales by Nintendo's Game Boy Color and lasted less than three years.

In 2000, ADK released its last video game title, Dynamite Slugger, and was primarily focused on developing content for Japanese i-mode-based mobile devices.

In that same year came Neo Geo Battle Coliseum, a console and arcade fighting game featuring several characters from the World Heroes and Aggressors of Dark Kombat franchises.
