The copy protection is removed already. If you get a black screen by hitting enter, use
DOSBox for playing. Please read the game's discussion thread/use the forums' search function next time to not ask already answered question - thanks. And the Requests forum is only to ask for games not on site yet - if you have a problem not solved at Abandonia, open a thread at
Troubleshooting (manuals should be asked for in the game's discussion thread, I would say).
