> Let's say your interpretation holds water even though I, and the EFF in their handbook [https://www.eff.org/pages/unintended-consequences-fifteen-ye...], and the US legal system just a few months ago [https://www.pearlcohen.com/court-upholds-dmcas-anti-circumve...], do not believe is correct.

The case you linked to has nothing to do with the interoperability exception. I don't know how they could reject my view if they never touched it.

Also

> Nintendo may potentially argue that yes, you are completely right. You have the right to interoperability, in the sense that you are allowed to make a device which physically takes Switch cards, decrypts them, plays them, from the original card, does not copy it to storage media of any kind, and does not allow the user any semblance of a DRM bypass, or any way to resell the original card while maintaining a copy.

And they would be right, if copyright law didn't have an additional exception...

17 U.S.C § 117 - Limitations on exclusive rights: Computer programs (a)Making of Additional Copy or Adaptation by Owner of Copy.—

Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided:

(1)that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner, or

(2)that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the computer program should cease to be rightful.
