PlayStation 3 uses shaders compiled with NVIDIA's Cg compiler. The primary resource portion has a discernible header, but for the most part it is made up of the the _CGprogram structure, which is unfortunately not publicly documented and does not appear in any symbols. The secondary resource portion (present only in pixel shaders) is usually null, though it can sometimes contain garbage near the end. These do vary in size, however, indicating they are valid resources and get loaded into memory. See [https://developer.nvidia.com/cg-toolkit-download NVIDIA's reference manual] or the SCE PS3 SDK for more information.
For information on Xbox 360 and PC shaders, see Microsoft's documentation of [https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/dx9-graphics-reference-asm-ps-3-0 ps_3_0] and [https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/dx9-graphics-reference-asm-vs-3-0 vs_3_0]. Note that PC shaders are compiled at runtime from source code contained in [[Shader
PC (Remastered) and PlayStation 4 shaders were compiled with Microsoft HLSL 10.1. The format appears identical on both platforms; this is likely true on Xbox One as well. See [http://timjones.io/blog/archive/2015/09/02/parsing-direct3d-shader-bytecode Tim Jones' blog post] on parsing the DXBC format for more information. Note that because PC hardware configurations differ, the compiled shaders that ship with PC (Remastered) are optimized at runtime; these are not cached.
