I think you are into something here.
I tried creating an emulator for CPU that is very well known but lacks working open source emulators.
Claude, Codex and Gemini were very good at starting something that looked great but all failed to reach a working product. They all ended up in a loop where fixing one issues caused something else to break and could never get out of it.
When they get stuck, I find adding debug that the model can access helps. + Sometimes you need to add something into the prompt to tell it to avoid some approach at a point.
I’ve been trying to do the same thing as a hobby project to just imagine some “what ifs” with some slight changes to the original 8086 and the 80286.
It just never produces an actually working result without a lot of intervention on my part. (My change was merely changing the paragraph size from 4 bits to 8 bits on the 8086.)
Please tell me what CPU it is. I would give it a try. I doubt strongly a very well documented CPU can't be emulated by writing the code with modern AIs.
Interesting. When I had Claude write a language transpiler it always checked that tests passed before declaring a feature ready for PR. There was never a case where it gave up on achieving that goal.
