Celine has found a screenshot and a little description from a misterious Saturn adventure game, that was know as “Chinese Detective”: we cant find any more informations about this title and it could have been cancelled, or maybe released with a different name. Do you have any clue?
Thanks to Celine for the contribution!
Update: this game was really released for the Saturn as “WanChai Connection“, you can find the final boxart and some infos at Segagaga Domain. Thanks a lot to Yakumo for the information!
