I see.

Regretfully, I probably will not undertake reviving the development for
16 bits-systems.
(For better or worse, nowadays it would hardly have any practical value)
Otherwise, as I see it, platforms' limitations do not necessarily lead to
limitations in fuctionality, but possibly to a more resource-efficient
design. Having done a lot of production work on 16-bit systems before
the 32-bit era I know they are quite capable.
Thanks for your work on Nano-X.
