That feature has no high priority for development. You can use xz format instead of gzip.

fb parameter is about number of bytes. 7-Zip GUI uses "Word size" field for that parameter. "Word size" in help file: Specifies the length of words, which will be used to find identical sequences of bytes for compression.

If you have implemented unrar5 unpacking, then you probably looked C++ source code of unrar. And you understand that code. So you can look another C++ code of unrar or code of 7-ZIP for any feature that doesn't work still.

Unfortunately, I don't have knowledge about C++. I coded mainly in Turbo C in the 1990 years, it's a long time ago but never practiced as a job, so no more C since 1996. I forgetted the base of the langage, so I prefer to say that I'm a noob in C. I don't have any C++ compiler and doesn't know how to configure it to compile and trace 7-zip in debugger :-( . I've a very good bagage in Java but not in C++. Do you also code in java ? Best regard, SteF.
