--- Comment #50 from joaopa jeremielapuree@yahoo.fr --- I have news for the demo not working. It is a problem with pixel format not recognized.
With a player.ini created in the game folder if I use 800 600 32 1 BaseCMO.cmo it works if I use 800 600 16 1 BaseCMO.cmo it does not work
800 is width 600 height 1 is fullscreen and 16 (or 32) is depth format.
You can change values 800 and 600. It does not matter.
