Sorry to bring this thread back from the dead, but recently someone posted a patch for the games based on the Dark Engine onto a French forum. Hours in, and this has basically created a stir over at the fourms. In fact, within the first day, 1000 uers had been logged in at once onto the forums.
Here's a link to the first English announcement: http://www.ttlg.com/forums/showthread.php?t=140085
We have no clue who made it, but we're all more than certain it is thanks to game_player_s that the creator was able to recreate the engine and update it for modern systems.
I can't say it enough: Thank you very much, game_player_s!
