Publishers are absolutely terrified "preserved video games would be used for recreational purposes," so the US copyright office has struck down a major effort for game preservation

A three-year fight to help support game preservation has come to a sad end today. The US copyright office has denied a request for a DMCA exemption that would allow libraries to remotely share digital access to preserved video games.

"For the past three years, the Video Game History Foundation has been supporting with the Software Preservation Network (SPN) on a petition to allow libraries and archives to remotely share digital access to out-of-print video games in their collections," VGHF explains in its statement. "Under the current anti-circumvention rules in Section 1201 of the DMCA, libraries and archives are unable to break copy protection on games in order to make them remotely accessible to researchers."

Essentially, this exemption would open up the possibility of a digital library where historians and researchers could 'check out' digital games that run through emulators. The VGHF argues that around 87% of all video games released in the US before 2010 are now out of print, and the only legal way to access those games now is through the occasionally exorbitant prices and often failing hardware that defines the retro gaming market.

Still, the US copyright office has said no. "The Register concludes that proponents did not show that removing the single-user limitation for preserved computer programs or permitting off-premises access to video games are likely to be noninfringing," according to the final ruling. "She also notes the greater risk of market harm with removing the video game exemption’s premises limitation, given the market for legacy video games."

That ruling cites the belief of the Entertainment Software Association and other industry lobby groups that "there would be a significant risk that preserved video games would be used for recreational purposes." We cannot, of course, entertain the notion that researchers enjoy their subjects for even a moment. More importantly, this also ignores the fact that libraries already lend out digital versions
