A lot of old consoles are actually based on standard CPUs for the most part. Look at the history of the 6502 for example. Emulating the hardware can be done if time is taken to reverse engineer all the layers into an emulator.

Part of the issue, to me, can be if all the work is done and then copyright disputes arise- all work has to be removed from the public.

This was a fast response, and doesn’t cover the whole scope of handling networking in docker. As mentioned elsewhere there is a different network philosophy for Standalone Containers & Overlay networking.

You declare the ip in your setup, or in the yaml file. An example for the docker-compose file is in the link below. I’d expect you’ll want to declare the network and such as well, if you’re not familiar.
