Query: This is NOT DirectX8

Well Ian while I admire your effort to write a book in the area, you have not done it justice. Firstly you concentrate ONLY on sprite based arcade games (these days a very small market share). Secondly, I cannot find a DirectX8 call anywhere in the source. This is going to be VERY misleading to an already confused group. People are struggling to get familiar with the DirectX8 characterstics and you have not taken any time to check it out for yourself. This book is DIRECTX 7 and is NOT up to date....
