lol, EV was special. It was also pretty easy to mod with plug-ins using macos resource fork hackery, even to a kid, and all of the original game data was replaceable just by creating something with the same ID in a plug-in. Cap’n Hector became an angry invincible shuttlecraft with a single laser cannon. now that I’m old enough to afford a license, the company is gone and there’s no way, so I guess I’m stuck with him like this forever.
ultimately, you will need some kind of access to something with at least one port open, if you intend to host services on the clearnet. you could use tor if onion services will work for you. if you have ssh access somewhere with a port open (or a friendly sysadmin), you could tunnel to there and redirect incoming connections back through the tunnel. same thing with a VPN, if the sysadmin is really friendly.
the magnetic domains slowly relax. if you plug it in once or twice a decade, you can significantly reduce the changes of that happening to an extent that you lose data.
