Donkey Me is a fan project by Bruno R. Marcos which takes Nintendo's classic arcade game and gives it a ton of new, unofficial "themed" expansions, based on stuff like Star Wars, Conan, Rambo, Indiana Jones and Big Trouble In Little China.
He's hoping to have it out in the next few days. It will be, of course, free. Keep track of its release by following Bruno's Twitter.
