A user called CRTdrone has posted a few pictures of the extremely rare cd-i Golgo 13 game on flickr, it appears to be some sort of visual novel game so I wouldn't expect much action.
This game and Cyber Soldier Sharaku are the rarest cd-i games since they were only released in Japan by a company called JIM, there are a few other kids titles by JIM which has been dumped though.
