“Most of the world’s video games from close to 50 years of history are effectively, legally dead. A Video Games History Foundation study found you can’t buy nearly 90% of games from before 2010. Preservationists have been looking for ways to allow people to legally access gaming history, but the U.S. Copyright Office dealt them a heavy blow Friday. Feds declared that you or any researcher has no right to access old games under the Digital Millennium Copyright Act, or DMCA.”
The most popular games will likely continue to get pirated, all this will do is guarantee that some small vintage games are lost to time.
