If it's still present once the MCU is decapped and dumped I'll consider looking at it, but until then the simulation is highly questionable.

It then subroutine jumps to main RAM and executes this code. Here, we're just returning a RTS instruction for now. See above ghox_mcu_w routine. */ There is some handcrafted code in there to provide some functions, but I doubt it's been verified against the real hardware, and at the end of the day the Z180 dump is needed before sound will work anyway. The Toaplan2 Z180 dumps are some of the 'essential' decaps that really need doing as a high priority. (I don't even think Guru / Dr. have a Ghox tho)
