I did something similar on the Trillek virtual computer, but without the trick of the 64bit int to store the bus state. Instead I used a bit high level aproximation as the CPU is far more simple, there isn't a IO address space, and there isn't wait states. What I did was a tick-instruction hybrid approach instead a tick-instruction cycle hybrid.
