Existing configuration files for +DOS Doom should therefore simply work out of the box. However, +Chocolate Doom also provides some extra settings. These are stored +in a separate file named 'chocolate-doom.cfg'. + +Options: + + fullscreen If 1, the game runs fullscreen. + + grabmouse If 1, the mouse pointer is "grabbed" during play. + This is only applicable if playing in windowed mode + (not fullscreen) + + mouse_acceleration Controls the acceleration applied to the mouse. + Acceleration has the effect of turning a greater + amount when the mouse is moved quickly. When this has + a value of 1.0, there is no acceleration. Larger values + apply a greater acceleration. + + novert Emulates the behavior of the DOS program "novert". + If this is 1, vertical mouse movement is ignored, + and the player will not move forward and backward + when the mouse is moved. + + screenmultiply If this has the value 1, the game runs in a 320x200 + window.
