Now I don't have time, but since it's like checking games into requests forum I can give you all some hint, especially to Paco
First, remember to check
MobyGames, second, try at Wikipedia, third, you can search info on other abandonware sites (xtcabandonware, cdosabandonware), HOTU Oldwarez list is a bit old because it's all Freezed there, but it's still good. Remember to not search into leechers cathegory (for example @ "free-game-downloads", that site is a bad Cut&Paste from other sites.)
Sometimes
Amazon could help you a lot, but they often do some confusion about Producers & Developers.
Last useless hint...Google is your friend :amused:
