It seems to me that, while console games may not be great literature, they are nonetheless of some interest, and steps should be taken to preserve them for posterity. Emulation is a good starting point; emulators exist for many gaming systems, from the Atari 2600 through the Nintendo 64.
However, emulation alone doesn't let you play games; you also need copies of the games. With CD-based games, it's fairly easy to simply play existing copies in a computer's CD-ROM drive. With cartridge-based games, however, special hardware must be used to extract the bytes. Worse, the same legislation that (probably legitimately) bans the creation of "backups" of games (used mostly for piracy, frankly) probably also bans these.
The purpose of copyright law is to create a deal whereby creators are ensured some reasonable control over their created works. However, in the case of video games, by the time copyright has expired on a game, the chances are that the technology to read it will be long lost; who imagines being able to find a functioning Nintendo system in seventy-five years?
With this in mind, I propose that copyright law be amended to allow for unrestricted copying and distribution of certain items. The exact rule, it turns out, is very hard to craft; the intent is to allow the archival of media that are on the verge of becoming unreadable - but before they become unreadable.
The intention of this is not to compete with the sale of new video games - indeed, most people would have no interest in older video games. Rather, it's to provide a way for enthusiasts and collectors to preserve the data and machine specifications.
Is this really useful? Probably not. However, copyright law has been based on the knowledge that a work will survive past the time when it leaves copyright and enters the public domain. With the creation of works which cannot survive that long, we need to consider changing the duration of copyright for these works.
This isn't to say that such programs should enter the public domain entirely. However, I think that Sega could survive in a world in which, ten years after the last Sonic the Hedgehog cartridge was made, people were welcome to copy old Sonic the Hedgehog cartridges, even though Sega could still retain ownership of the Sonic character, and full protection on newer games.
