MirrorReflection4 (unifyCommunity) Shader - Version with bump/normal map

Hello, I need the MirrorReflection4 shader from Unify with normal map (preferably with spec map) but i can't write HLSL/Shader.

http://wiki.unity3d.com/index.php/MirrorReflection4

Can anyone help me to enhance the mirror shader with those attributes?

Thanks!

Code (csharp):

1.  
2. Shader "FX/MirrorReflection"
3. {
4. Properties
5. {
6. _MainTex ("Base (RGB)", 2D) = "white" {}
7. [HideInInspector] _ReflectionTex ("", 2D) = "white" {}
8. }
9. SubShader
10. {
11. Tags { "RenderType"="Opaque" }
12. LOD 100
13.  
14. Pass {
15. CGPROGRAM
16. #pragma vertex vert
17. #pragma fragment frag
18. #include "UnityCG.cginc"
19. struct v2f
20. {
21. float2 uv : TEXCOORD0;
22. float4 refl : TEXCOORD1;
23. float4 pos : SV_POSITION;
24. };
25. float4 _MainTex_ST;
26. v2f vert(float4 pos : POSITION, float2 uv : TEXCOORD0)
27. {
28. v2f o;
29. o.pos = mul (UNITY_MATRIX_MVP, pos);
30. o.uv = TRANSFORM_TEX(uv, _MainTex);
31. o.refl = ComputeScreenPos (o.pos);
32. return o;
33. }
34. sampler2D _MainTex;
35. sampler2D _ReflectionTex;
36. fixed4 frag(v2f i) : SV_Target
37. {
38. fixed4 tex = tex2D(_MainTex, i.uv);
39. fixed4 refl = tex2Dproj(_ReflectionTex, UNITY_PROJ_COORD(i.refl));
40. return tex * refl;
41. }
42. ENDCG
43. }
44. }
45. }
