Didn't Claude Fable do this? (and I think codex and Claude Code in general)

When Fable was around last week, I was smitten with it. I took an executable file from an old DOS application, told it to port it to the Mac. From that single prompt, it was able to set up a test rig with Dosbox to execute the application after already disassembling and gathering as much info as it can and then continuously refine the output application while testing it against the original file. 15 minutes later it had an 99% identical looking and functioning application running natively on the Mac. Sone final refinements got that to 100%.
