Sony Quietly Adds PS2 Emulation To the PS4 (eurogamer.net) 151

An anonymous reader writes: The Digital Foundry blog reports that Sony has added functionality to the PlayStation 4 that allows it to act as an emulator for some PlayStation 2 games. Surprisingly, the company did not mention that this functionality is live; a new Star Wars game bundle just happened to include three titles that were released on the PS2. From the article: "How can we tell? First of all, a system prompt appears telling you that select and start buttons are mapped to the left and right sides of the Dual Shock 4's trackpad. Third party game developers cannot access the system OS in this manner. Secondly, just like the PS2 emulator on PlayStation 3, there's an emulation system in place for handling PS2 memory cards. Thirdly, the classic PlayStation 2 logo appears in all of its poorly upscaled glory when you boot each title." Sony has confirmed the games are being emulated, but declined to provide any further details.

      The compatibility of this emulator must be quite bad, given the fact they must be using all sorts of speedhacks and multithreaded insanity that leads to innacuate timing to make the quite weak jaguar cores handle emulation in realtime and probably the emulator must require per game tweaking as happens with the nintendo 64 emulation on the Wii virtual console.

    As someone who has never had a console, do I understand correctly that people normally have to re-buy games when they upgrade their consoles? i.e. not like a PC where something 20 years old can, sometimes with a bit of hacking, still be played on your current machine.

    That's... ugh... do you just stack all your consoles in your living room so you can select the appropriate one for the games you have? Are you people made of space and money?

      This is precisely why I'm shying away from console games now. It wasn't too bad when the PC would gain emulation for the console titles over time (e.g. I can play nes, snes, n64, gameboy, playstation, playstation 2, gamecube, psp, nintendo ds, and wii titles fine on PC now), but as of PS3/Xbox360, things have gotten to the point where the chances of workable emulation are limited for the forseeable future.

      • This is all true, but it's slightly offset by the recent trend to re-release (and modernise) some of the more popular previous-gen games.

          Note that a lot of games I revisit are not on the popular list.

          I do however wonder if finally getting into the x86 architecture means they will have more x86 sensibility with respect to backwards compatibility moving forward.... On the other hand they may recognize the cash cow for now work that is rereleasing...

          • getting into the x86 architecture means they will have more x86 sensibility with respect to backwards compatibility moving forward

            True, but if the games are using low-level graphics APIs, you're only half-way there.

    • Yes and no, some games do get re-released in an updated format and some users will pay for that. The rest of us tend to keep the old consoles and the few games we truely love, in a box somewhere that gets dusted off and used once every leap year. The upside to this is there's no "hacking" to get something working. And if we're talking 20 year old PC titles, well, we're into the territory that you have to ensure your sound card (yes, they did exist as their own card) and video card are actually supported

        I bought a new video card recently for 200. The previous one lasted around 5 years and it was purchased for about 250. It kept up with most games rather nicely and only started showing its age with newer titles about a year ago. Ram and processor are good for a while yet. 8GB DDR3, Phenom 2 1090t

      • I don't think keeping a PC constantly up to date is really necessary to enjoy a majority of games. Sure some people spend hundreds of dollars on multiple video cards, high end processors and fancy monitors from Korea but it's not necessary. Mostly because so many PC games are optimized for console hardware released 10 years ago. If your monitor only goes to 1080p you can usually max out the specs anyway. You can run a 4 year old video card and still enjoy most PC games. Because as I said unless you want so

Yeah, I spent a stack of cash on my monitor (mainly for Photoshop), but otherwise, I have a 6 year old (bought 5 years ago for about $100) AMD quad core processor & 8GB RAM (and a small SDD + large HDD) - it doesn't take much to get a better experience than consoles.

        Most actually vintage titles get GoG releases. Many can also be emulated in DosBox just straight up.

        Basically, if you don't want to keep your old PC hardware around (as you obviously do your old console hardware), then you have to take steps in software to play the games. With consoles, you don't have the second option at all- though the first option is a bit easier.

    • Yes and no. Backward compatibility is more common than people mention, but because the actual architecture and media of consoles change from generation to generation, consoles as a whole aren't backwards compatible.

        Except anything in the Game Boy or Nintendo DS line, which support at least one generation of back-compat: GBA and GBA SP can run Game Boy and GBC games, DS and DS Lite can run GBA games, and 3DS, 2DS, and New Nintendo 3DS can run DS games.

        I'm pretty sure I know people who have several game consoles spanning a very long time .. like back to their Super Nintento.

        That and there are still third-party games coming out for the original Nintendo Entertainment System, three decades after the console's launch.

        if it still works and there are games you still like .. why just throw it away?

        Presumably to save recurring rent/property tax money by moving to a smaller home.

      • Most things with CD tried to be backwards compatibility, most things with cartridges not so much.

        That's not really accurate. Sure the Playstation line was Backwards compatible up until half way through the PS3's life span but none of the Sega Disc based consoles were BC. However Sega's Genesis could play Master system games with the appropriate adapter. (the adapter was really only there for the slot to accept the cartridges). Also the Atari 5200 and 7800 could play 2600 games. The gameboy's were almost al

          This was a major error from Atari; that and the 5200 joysticks.

    • It varies.

      In the old day each new console was a very different system that was basically totally incompatible with it's predecessors, if you wanted to keep playing your old games you had to keep your old consoles around. Sometimes a game would be re-released for a newer console but this was the exception not the rule. If a game was re-released and you wanted to play it on your new console then yes you did have to re-buy it. Often such games were packaged together into compilations for the re-release.

      • Not as much of a trend as you think. Atari 7800 was compatible with 2600 games. Sega broke that trend as well. Mega Drive was backcompat with Master System, and 32x was also backcompat with Mega Drive by way of being an addon (as you could put your MD cats on top of the 32x and they would generally work).

        Also Nintend broke that trend in handheld - all GBA systems but the GB Micro could play original B&W GB games. Each successive handheld has at least supported one previous generation of consoles.

      We just keep the old consoles. They're not that big -- maybe a foot across. And (until they got internet connectivity) they were mostly guaranteed to work forever without user intervention.

      Backwards compatibility on PCs was not trivial before DOSBox, and I understand that running Windows 3.1 games is still pretty difficult. Keep in mind that consoles don't have a single standard architecture. Different consoles in the same generation are not compatible, and the hardware on consoles changes much more from ge

    I'm sure a PS2 emulator has novelty value but I'm not sure many people will really be that interested. Wouldn't a PS3 emulator make more sense given a lot of PS4 owners may still have a PS3 to play PS3 games and might prefer one console to do both? Or is the PS4 simply not powerful enough to do it?

      • I can't remember if it was PS->PS2, or PS2->PS3 ... but essentially they achieved backwards compatibility by making the CPU for the previous generation the front-end processor for the new generation.

        There have been several consoles like that. Sega Genesis included the Sega Master System CPU as a coprocessor mostly used for audio and a VDP that can fall back to Master System video modes. PlayStation 2 included the original PlayStation's CPU as the I/O coprocessor. Nintendo DS included the GBA's ARM7 as the I/O coprocessor.

        There are a few other approaches to backward compatibility. One is to overclock the same CPU (Game Boy Color, Wii), possibly with more identical cores (Wii U). Another is to disable the previous CPU entirely when running new games (Game Boy Advance, PlayStation 3 with SACD logo).

    • by Junta ( 36770 )

      PS2 is easier. Note this is probably like the PS1 emulation in PSP, good enough to work almost all the time, but limited by Sony to make sure a given title works and/or is tweaked to work under the emulator before blessing it.

      Also, porting from PS3 might be more in reach for companies than PS2 back catalog, simply because being newer means they are more likely to still have the assets to build the title.

    • by tepples ( 727027 )

      I'm sure a PS2 emulator has novelty value but I'm not sure many people will really be that interested.

      It's the same logic as the Virtual Console section of Nintendo's Wii Shop Channel. Only a PlayStation 2 emulator can play PlayStation 2 exclusive games. A heck of a lot of those were produced for a console that clearly outsold the contemporary Xbox and GameCube consoles. Emulating the PlayStation 2 allows SCE and participating game publishers to produce revenue from these games.

      Or is the PS4 simply not powerful enough to do it?

      I suspect that to be the case. PlayStation 4's processor (a 64-bit Jaguar, DO THE MATH) is reportedly clocked lower than PlayStatio

      • Who cares about clock speeds? Even if the PS4 had a current-day top-of-the-line CPU, emulating a Cell processor with usable performance would be an enormous -- probably impossible -- task.

        The Cell is quite exotic: it's radically different from most CPUs. I imagine it would be a nightmare for software emulation.

        On top of that, you'd have to emulate the GPU, which would another enormous (maybe impossible) task.

        A more practical alternative would be to set our sights lower, and for Sony to create tooling to sim

        • by cfalcon ( 779563 )

          The PS3 was going to have this problem from the start- the cell architecture was just too exotic. The only way we would have PS3 emulation on the PS4 is if the PS4 kept to that exact design concept- and that's just punting the problem to whenever it's no longer wise to keep down that design path.

    • I'm sure a PS2 emulator has novelty value but I'm not sure many people will really be that interested.

      Sony's solution is Playstation NOW. It is a streaming service to let you play PS4 games on your PS4 using a streaming "rental" model. The plan is to include PS3 games at some point.

    • Keep in mind the ps3 (cell) had a totally different architecture where the ps4 is off the shelf (mostly) pc components. They are offering a paid streaming service for some (all?) ps3 titles. That's why just giving us an emulator will never happen. Why spend time and money developing this to give it for free when you can make me buy those games again, or better yet sucker me into a subscription.

At least they recoup their investment from testing games and making their money in that way.

    The big unanswered question is whether Sony will allow users to play PS2 games from their original discs. On the basis of what we've seen so far, there would appear to be no reason why this isn't feasible.

    The worry, however, is that Sony wants restrict the system to online purchases made via a PS4, so that people who want to play PS2 games on a PS4 need to purchase the titles again, even if they own the original discs (and with probably only a tiny portion of the PS2's library being available for purchase).

    • by Junta ( 36770 )

      I suspect more it's a carry over of the capability from PS3. Not the original hardware capability to play the discs, but the later capability they had to help developers massage PS2 games to work on PS3 through their online store. It wasn't able to flat out run an existing game unmodified, but mitigated the amount of stuff a developer had to do to get it to run on a PS3 by emulating a lot of the stuff that was within reach.

  • When the Wii began offering SNES games, nobody called it a "SNES emulator." This is exactly what PS4 is doing, they're adding PS2 games onto the marketplace for PS4 (which may or may not be using an emulator, who knows/cares). But you cannot insert PS2 discs and expect it to work.
