The Apollo missions were very different, for example, Apollo 7 was only an orbital flight, while Apollo 9 was always an orbital flight with a series of maneuvers for the LEM test. Apollo 8 (mission made for testing of the modules, but lacking the LEM not yet completed) has only tested the lunar orbit insertion (10 orbits) restarting the engine and return to Earth. The other missions rather have tested and used the LEM completely.
The Space Shuttle has shown that can place various "scenarios" which manage very different parts of the flight.
Using this technique it is possible to reproduce parts of the flight also based on real telemetry data.
The Apollo technology is not very different from that of the space shuttle, of course, were different computers because Apollo was operating with a direct link system with the control center and with the help of a computer

Here there is an example of a python version:

They might start with Apollo 7, which only used the Apollo capsule + emergency eject system.
