1. I tried to mail creators of Spectromancer/Astral Tournament. No any answer.
2. Well, Edo's Yu-Gi-Oh was free game, based on Yu-Gi-Oh rules, quite stable, without any copyrighted pictures to avoid issues (but with much of official rules). Pictures still could be inserted, if you have files for it - game supports it. Project was maintained up to 2007. Then creator suddenly lose interest in it, and... well, that's all about it. Game page still can be accessed
here. And
here is link for latest build (not one on the site), sources and (I think, copyrighted) pictures that can be inserted in game.
