I am going to use old 2D graphics at a high resolution. The idea is to bring old 2D graphics to a higher resolution. I think it can be easily done with 1600x1280 now by using 64bit or 128bit variables and a big variable for the pointer to a directx surface like this:
unsigned long long *surface;
surface = (unsigned long long *)directdrawsurface;
..and then set the graphics accordingly with
surface[0] = RGBAcolor;

yup works just fine.

highres_surface->Lock(NULL,&ddsurfacedesc,DDLOCK_WRITEONLY|DDLOCK_NOSYSLOCK,NULL);
//highres_surface->Lock(NULL,&ddsurfacedesc,DDLOCK_WRITEONLY,NULL);
unsigned long long *s = (unsigned long long *)ddsurfacedesc.lpSurface;
s[0]=0;
highres_surface->Unlock(NULL);
