Hopefully this will be interesting to the DOS verison enthusiasts here. I was playing around with pixel shaders that are included in DOSBox SVN Daum, and realized that several of them will alter the image so that it looks like real CRT screen output. One of the shaders goes as far as to imitate the curved surface of an actual CRT display: Another shader creates a less noticeable surface distortion: To set up DOSBox SVN Daum to use these shaders, you'll need to change the following lines in dosbox.conf: [sdl] output=direct3d pixelshader=CRT-geom-curved.fx [render] aspect=true scaler=hardware2xCRT-geom-curved.fx creates the "fishbowl" effect pictured in the first screenshot above. CRT.D3D.fx is shown on the second screenshot. CRT.D3D.br.fx is a brighter version of CRT.D3D.fx. Also there's CRT-geom-blend.fx, which is similar to CRT-geom-curved.fx but also adds motion blur. All these will work both in the windowed mode and in fullscreen. You can also get higher resolution images by using hardware3x, hardware4x and hardware5x instead of hardware2x:
