ADK. Where are they now?

Who were ADK? All the information I can find on them seems to link them with SNK, can find any information that they existed before SNK and can't find that they exist now.

The only non Neo Geo game I can find that they released was Twinkle Star Sprites on the Saturn (Dreamcast version was by SNK).

I've heard that ADK was a subsidary company of SNK, but is this true?

They were. up until 2001.... who knows where that staff is now.

They were a second-party company with SNK (think Rare to Nintendo, were anyways). They had some funnnnnnnn games going on. I'm really curious as to what happened to the people who make the fun. drool_2
