I know there are many people who find this appalling and wish that companies did more to re-release their older titles, but I've frankly just accepted that emulation will be the best and perhaps only way to play a majority of these titles. Unlike movies, where you simply need a method to playback a video and audio stream, getting interactive media to continue working isn't trivial, especially since it needs to run exactly as it did before (otherwise what's the point). I wish rather than taking the effort to port the game themselves, they'd be more receptive to fan preservation efforts, although some companies are more friendly towards this than others. It's a bit of a self fulfilling prophecy. The more people ask for older titles to be re-released, the more developers realize there's a market for it, so rather than release the source or future-compatible files, they instead will port the game to their latest system once a decade to resell it.
