This is very wrong. Ghidra might decompile to some C code, but this is a completely different, and very high bar. This is 100% matching C code that compiles to the exact binary the game shipped with. This means it's able to be modified, tweaked and upgraded. Ghidra is helpful to do some research, but it won't compile.

That's not what the parent comment said: "100% decompiled to C, but not fully labelled yet".

Getting the exact same binary is definitely something else. Figuring out the exact compiler version and options, libraries, etc. is itself nontrivial.
