The current emulation only supports 32 bit writes to the "port" address.
I'll read the documentation to see how 16 bit writes should be handled
(obviously your image always writes lower and upper half of the 32 bit
value, and for this case, the solution might be simple).
Is prologue.img available online (so I can run your test scenario)?
Regards,
Stefan W.
