@lupyuen We ran into this during disassembly and decompiling. That's why I needed to make a custom processor to help decompile the code more accurately. It's a very odd core. Seemingly RV32GC, and is RV32GC, with some oddities.

There is a good reason why the computer I did my work on is setup exactly the same way as it was when I released the last code revision. All that work, all the documentation and the results of that effort are still intact. Is it the human readable version? Absolutely not. That would come later from you and even now it is an impressive work.
