Particularly for this adventure, I have kept it strictly private. It was a hobby project and also was a challenge to myself.
In the process I learned not only of M32C(backwards compatible with M16C processor module in Ghidra), but as I mentioned, certain compiler bugs(not following the ISA spec strictly) that it is more flexible despite what the M16/M32C software manual says. However this meant that emulation produced wrong results, and thus my patches to fix it and ultimate success
I have opened a Ghidra support ticket, but I needed to provide proof that there is ISA behavior not described in the software manuals.
