Well, funny you should mention it because this came out less than a month ago:

> Exemption to Prohibition on Circumvention of Copyright Protection Systems for Access Control Technologies
> [..]
> 1. Computer Programs — Video Game Preservation
> SPN and LCA petitioned to renew the exemption for preservation of video games for which outside server support has been discontinued. No oppositions were filed against readoption of this exemption, and Consumer Reports submitted a comment in support of the renewal petition. The petition stated that libraries, archives, and museums continue to need the exemption to preserve and curate video games in playable form. For example, the petition highlighted Georgia Tech University Library’s Computing Lab, retroTECH, which has made a significant collection of recovered video game consoles accessible for research and teaching uses pursuant to the exemption. [..] This existing exemption, as well as the above exemption pertaining to software preservation, serve as the baseline in assessing whether to recommend any expansions in Class 14.
