I Wouldn’t Get Your Hopes Up For Backwards Compatibility.

Us gamers tend to be hoarders when it comes to our game collections with many of us amassing huge stashes of titles on our platforms of choice. My steam library alone blew past 300 titles some time ago and anyone visiting my house will see the dozens of game boxes littering every corner of the house. There’s something of a sunk cost in all this and it’s why the idea of being able to play them on a current generation system is always attractive to people like me: we like to go back sometimes and play through games of our past. Whilst my platform of choice rarely suffers from this (PCs are the kings of backwards compatibility) my large console collection is in varying states of being able to play my library of titles and, if I’m honest, I don’t think it’s ever going to get better.

Gaikai BackgroundJust for the sake of example let’s have a look at the 3 consoles that are currently sitting next to my TV:

  • Nintendo Wii: It has the ability to play the GameCube’s games directly and various other titles are made available through the Virtual Console. Additionally all games for the Wii are forwards compatible with the WiiU so you’re getting 3+ generations worth of backwards compatibility, not bad for a company who used to swap catridge formats every generation.
  • Xbox360: Appears to be software level emulation as it requires you to periodically download emulation profiles from Microsoft and the list of supported titles has changed over time. There is no forwards compatibility with the XboxOne due to the change in architecture although there are rumours of Microsoft developing their own cloud based service to provide it.
  • PlayStation4: There’s no backwards compatibility to speak of for this console, for much the same reasons as the XboxOne, however my PlayStation 3 was a launch day model and thus had software emulation. American versions of the same console had full hardware backwards compatibility however giving access to the full PlayStation library stretching back to the original PlayStation. Sony bought the cloud gaming company Gaikai in July last year, ostensibly to provide backwards compatibility via this service.

For the current kings of the console market the decision to do away with backwards compatibility has been something of a sore spot for many gamers. Whilst the numbers show that most people buy new consoles to play the new games on them¹ there’s a non-zero number who get a lot of enjoyment out of their current gen titles. Indeed I probably would’ve actually used my PlayStation4 for gaming if it had some modicum of backwards compatibility as right now there aren’t any compelling titles for it. This doesn’t seem to have been much of a hinderance to adoption of the now current gen platforms however.

There does seem to be a lot of faith being poured into the idea that backwards compatibility will come eventually through cloud services, of which only Sony has committed to developing. The idea is attractive, mainly because it then enables you to play any time you want from a multitude of devices, however, as I’ve stated in the past, the feasibility of such an idea isn’t great, especially if it relies on server hardware needing to be in many disparate locations around the world to make the service viable. Whilst both Sony and Microsoft have the capital to make this happen (and indeed Sony has a head start on it thanks to the Gaikai acquisition) the issues I previously mentioned are only compounded when it comes to providing a cloud based service with console games.

The easiest way of achieving this is to just run a bunch of the old consoles in a server environment and allow users to connect directly to them. This has the advantage of being cheaper from a capital point of view as I’m sure both Sony and Microsoft have untold hordes of old consoles to take advantage of, however the service would be inherently unscalable and, past a certain point, unmaintable. The better solution is to emulate the console in software which would allow you to run it on whatever hardware you wanted but this brings with it challenges I’m not sure even Microsoft or Sony are capable of solving.

You see whilst the hardware of the past generation consoles is rather long in the tooth emulating it in software is nigh on impossible. Whilst there’s some experimental efforts by the emulation community to do this none of them have produced anything capable of running even the most basic titles. Indeed even with access to the full schematics of the hardware recreating them in software would be a herculean effort, especially for Sony who’s Cell processor is a nightmare architecturally speaking.

There’s also the possibility that Sony has had the Gaikai team working on a Cell to x86 transition library which could make the entire PlayStation3 library available without too much hassle although there would likely be a heavy trade off in performance. In all honesty that’s probably the most feasible solution as it’d allow them to run the titles on commodity hardware but you’d still have the problems of scaling out the service that I’ve touched on in previous posts.

Whatever ends up happening we’re not going to hear much more about it until sometime next year and it’ll be a while after that before we can get our hands on it (my money is on 2016 for Australia). If you’re sitting on a trove of old titles and hoping that the next gen will allow you to play them I wouldn’t hold your breath as its much more likely that it’ll be extremely limited, likely requiring an additional cost on top of your PlayStation Plus membership. That’s even if it works as everyone speculating it will as I can see it easily turning out to be something else entirely.

¹ I can’t seem to find a source for this but back when the PlayStation3 Slim was announced (having that capability removed) I can remember a Sony executive saying something to this effect. It was probably a combination of factors that led up to him saying that though as around that time the PlayStation2 Slim was still being manufactured and was retailing for AUD$100, so it was highly likely that anyone who had the cash to splurge on a PlayStation3 likely owned a PlayStation2.
