Not even remotely similar. A copyright banner isn't even a mere instrumentality because copyright law already protects the ROM; the banner is redundant. (see http://www.copyright.gov/circs/circ03.pdf. Notice was required by the 1976 Copyright act but after the US adopted the Berne Convention notice became optional.)

On the other hand, mail headers and other such meta are frequently necessary to provide the service. The very act of using email requires giving one or more headers to one or more third-party email providers; the very act of making a phone call requires giving phone number information to one or more phone service providers.

I'm not sure how that case is relevant to your point. In that case, Sega used a TMSS file as a hardware check to make sure games were properly licensed. Acclaim copied this file and included it in their games after reverse-engineering some demo games. This was eventually found to be fair-use since it was required to run their games but there was no technical reasons for the use of the TMSS file.

That's different from the point you were trying to make. The provision of email addresses and phone numbers are inherently necessary for an email provider or telephone service provider to provide those services. They aren't just incidental data--they're a fundamental part of the service transactions at issue.
