Just a few things to note:

Loading a bmp, the format becomes D3DFMT_R5G6B5 ( 23 )
Loading a tga, the format becomes D3DFMT_X8R8G8B8 ( 22 )

Calling bmap_to_uv(), makes it D3DFMT_V8U8 ( 60 )
Calling bamp_to_normals(), makes it D3DFMT_A8R8G8B8 ( 21 )

Vertex shader:

vs.1.1



dcl_position v0

dcl_texcoord v1



m4x4 oPos, v0, c3 ; transform position to the projection space



; Compute vertex position in the camera space - this is our texture coordinates

dp4 r0.x, v0, c0 

dp4 r0.y, v0, c1 

dp4 r0.z, v0, c2 



; Do the rest of texture transform (first part was combined with the camera matrix) 

rcp r0.z, r0.z 

mad oT1.x, r0.x, r0.z, c8.x 

mad oT1.y, r0.y, r0.z, c8.y 



mov oT0.xy, v1     ; Copy input texture coordinates for the stage 0;
