If you look at the 1974 8080 Assembly Programming Manual, there is not much to do. "Appendix A Instruction Summary" describes each operation in handy pseudocode. All you need to do is to make an interpreter for these:
CALL ADDR: ((SP)-1) <-- (PCH), ((SP)-2) <-- (PCL), (SP) <-- (SP)+2, (PC) <-- ADDR
