I'm not great at reading Z80 but I've emulated a fair amount of stuff running on it just from hooking it up and watching the memory access patterns. One of the great benefits of working within the MAME framework is that the CPU cores do what they're supposed to and you don't have to reverse-engineer the ROM code to make something run.
