If it seems like the topic of preserving antiquated video games as art keeps coming up, that's because it's very much starting to become a popular topic in the gaming industry and among the gaming public. The headwinds facing the proper preservation of this ever-growing subsect of culture are fairly clear. The very tools that have been used by fans to keep these older games alive and playable have too often been viewed as a threat to some gaming companies. As with all things in life, copyright is also getting in the way, as are some industry groups coming out against vile threats like museums and curation groups looking to keep old games alive for the public. Even preserving old game manuals is a prospect that only survives because of fair use.

One recent suggestion we discussed was to make it part of the the game development culture to publish the source code for any PC game publicly. If this sounds like a bonkers idea that would risk a game developer all of its income, well, Doom did this, so no you're wrong. But, as we also discussed recently when Sony officially announced it was ceasing support of the PlayStation Store for PSP, Vita, and PS3 owners, this suggested cure does zero for console games.
