In The '90s, ADK only made games for Neo Geo arcades and consoles until 2000s, where finally went to bankruptcy. After that, SNK bought ADK properties and inserted them into SNK Universe, starting with the Crisis Crossover Fighting Game NeoGeo Battle Coliseum in 2005, where apart of SNK licences (prominently The King of Fighters) were added as well characters from World Heroes and Aggressors of Dark Kombat, some of ADK's famous games in The '90s. And that was just the beginning.
ADK made a variety of games: in The '80s made various Sport Games and Combat-Flight Simulation Games, some of them licenced by external companies as SEGA and SNK (before they were third-party of them), but in The '90s ADK expanded more making Action-Adventure Games and Fighting Games, being World Heroes series probably the most famous title of the company (and the only known for many). After their bankruptcy, ADK lives more than ever in SNK, whose characters are in various SNK titles mostly as cameos and making various re-releases of their most known titles.
Notably, the Neo Geo was actually designed by ADK for SNK, being an evolution of the 68k architecture used in ADK's late 80's games like Time Soldiers.
