hello everyone,

i wanna ask if someone can help me update the projection shader to DX9.

i wanted to do myself and went through the manual with all lines that are in there (i learned from it, but obviously not enough :P).
i came as far as to update 4 lines to DX9 code (which are stated in the code as a comment, you should see them ^_^ ).

anyone know what to update more on this code to get it to work, or does someone has me a HLSL code for this ??

hope someone can help.

Code:
