I posted that link on another thread today.
The main trick is to use the Duke palette for all of your work. The simplest way to get the palette is to extract one tile from Duke 3D and import the palette with it. Photoshop somehow garbles the palette, at least the version I used to use. If you are willing to switch to The GIMP, I'll explain how to do it with that program. Even so free, it is ten times better than Photoshop IMNSHO
Cheers.
