You can complain all you want, but there is no way anyone here is going to spend the time and effort trying to keep the DirectDraw executable working when Microsoft doesn't support it anymore and every update to Windows and/or DirectX further breaks it. If we kept focusing on DirectDraw, we're going to have a game that's virtually unplayable by everyone in two or three years.
Instead, we're going to do the obvious -- remove the DirectDraw code from future versions, and focus solely on improving SDL2's performance.
