Yeah, Mike Stewart did that many years ago. It was incorporated into a version of Orbiter that let you run the Apollo missions. It's on the ibiblio site that you were directed to and promptly ignored.
Downloaded his repo from Github, and having a look. It is very old, targeted at WindowsXP/Vista era.
His readme makes this statement:
"The repository contains the actual assembly-language source code for the AGC, for as many missions as we've been able to acquire" <== INCOMPLETE.
And:
"Virtual AGC is not a flight simulator, nor a lunar-lander simulator, nor even a behavioral simulation of the Apollo Lunar Module (LM)..."
So the setup is incomplete and abandoned. In order to validate this meaningfully, need a "Complete set of source code" as well as emulated components - and a simulation script of various feeds.
This is all stuff the would have HAD to do in 1968+ to validate it's operation/functionality/performance.
I saw a video a few months back of some young guy in a lab with a "full hardware setup" and data feeds to emulate more of the mission. Not sure where that video is now, have you seen it? This was the situation where "whatever they did for this setup" would have been immensely easier as a downloadable/shareable emulator suite...
CONCLUSION: There still exists no sufficient platform for validating this AGC and it's software.
So despite my cursory educated assessment - there's nothing I can viably prove here. So I'll keep my focus on the Physics, mostly.
