This is the supposed copyright holder to Bud Tucker (can't find a mention of Bud Tucker on their site, but Eutechnyx is where
www.the-underdogs.org took me). I guess you can try contacting them, but I have the feeling you'd end up in a corporate loop of bullshit even getting them to offer the game for sale, if they even have it. Might get lucky though.
