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.

It used a very simple custom encryption for the time stuff and AES in ECB mode.
Protip Ghidra does not emulate inherent CPU behavior of INDEX instructions, behaviour not specified in ISA. I had to backport M32C instructions and patch M16C slaspec to emulate this behavior, caused by compiler bugs.
