Hi you can always use the open sourced ddraw library from here:
https://github.com/CnCNet/cnc-ddraw/releases

It comes bundled with many different shaders but you can make you own or use any of the shaders from here they all provide a different look / result:
https://github.com/libretro/glsl-shaders/tree/master/

It is worth noting that you have to choose the renderer as being OpenGL to be able to use these different shaders in the ddraw.ini file and also set the shader to the one you want there.

renderer=opengl
shader=Shaders\stock.glsl

If you want the good old pixelated look the algorithm you are looking for is "nearest". You can download and use the stock.glsl file from that github and use it and it will give you a very pixelated look to your game just like you wanted.
I personally prefer using the xbrz-freescale or the 6xbrz.glsl for my game but it is up to you to choose which ever you prefer.

Hopefully that helps if you are looking for people to play with on battle.net we play every weekend there at 9pm GMT!
GLHF !
