Unknow file format

[jebbyk]

I'm trying to decompile some Richard Burns Rally shaders but no success. Could you please tell me what is wrong with this file? I know it is a some kind of pixel shader, but decompiler says it is unknown format

(actual file extension is a .pso)
CarColor.zip

Hey @jebbyk! Sorry to hear you couldn't use the decompiler. I've taken a look at your file and at some repo's code, and, although I'm not the project's maintainer, I believe the file you've provided contains Shader Model 4.0 shaders that are not fully supported by the decompiler yet (there appears to be some code dedicated to it but it seems incomplete). Hope that helps in some capacity.

Edit: to be more specific, the first 8 bytes of the file look like so: 01 01 FF FF FE FF 40 00. The code responsible for figuring out the file format tries to look for one of the sequences:

1. 52 47 58 41 in first four bytes ("RGXA" in ASCII)
2. FF FE 03 00 or FF FF 03 00 in the next four bytes.

Your file has none of those, hence the "Unknown file format" error.
