comment How to emulate Mode 13h in a modern 3D renderer?
Even if you keep a dirty flag you would still have to update every frame when there's a lot of things happening, plus as postgoodism said a 320x200 texture update will unlikely create a speed issue.

comment How do I multiply pixels on an SDL Surface?
You can also take the closest pixel instead of interpolating between them, but the result will be highly pixelated, using this method allows you to smooth the image and have a better result.

comment Confuse with OpenGL, SFML, and its library
Here's a good link for a modern OpenGL tutorial (most of the tutorials are deprecated and make use of the fixed function pipeline) : arcsynthesis.org/gltut I'm looking forward to your game :)

I'll take the example of Windows. You first got to get a Device Context, this is what let you draw in a window, then you need to create a Rendering Context to let OpenGL have access to this drawing area. This is a very simplified explanation of the steps you have to go through. The process of creating a drawing area for OpenGL is platform specific, but OpenGL itself is not.

Do you want to multiply a color by another color or something else ? Please explain what you're trying to achieve.
