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

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.

      Just so people don't get confused and think that "Other OS" was something that the PS4 previously had, it was a feature removed from the PS3.

      What I want to know is how many people whining about Other OS being removed ever used it or realized the limitations to it in the first place. Or understood the implications for their console (saturation levels of piracy and a death spiral into shovelware) if it had allowed to remain in place.

      And I fixed a bunch of security issues when I ran Windows Update this morning. Except that no, it's not really me that did that.

      You're also conveniently failing to mention that firmware updates aren't exactly optional. Some PS3 software (games or apps) require the most recent firmware, giving you the choice between keeping OtherOS, or keeping your PS3 usable for other tasks.

      Not that I've ever seen, no. It was about running Linux. It was tinkerers that used OtherOS, not pirates. Sony used the hypervisor to deliberately break GPU access, iirc, presumably to prevent gaming on OtherOS.

      Why hasn't the PC had a similar "death spiral into shovelware" despite being designed from the ground up for Other OS (with the exception of very few recent models with locked-down Secure Boot)? It has shovelware, as it is the first line platform for amateur productions, but why hasn't this caused "a death spiral"?

    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?

      There's probably a lot of old titles people would still play if they could, and which can probably make some additional revenue from.

      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. The theory was backwards compatible was essentially free.

      It's entirely plausible the PS4 can't emulate a PS3 fast enough ... but I bet there's a lot of side scrollers and other classic PS2 games people would still love to play.

      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.

      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 PlayStation 3's Cell Broadband Engine.

      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).

    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).

    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.

    I haven't had any problems emulating an SNES with add-on stuff like SuperFX and Mode 7 graphics since, oh.. 450MHz PII-based Celeron using ZSNES.

    ZSNES is fine if it runs the particular game you are trying to play. But it's not so fine for more obscure uses, such as compatibility with controller logs for console-verifiable speedruns, development of game mods and original games that work on the original console, and even a few games. From ZSNES Readme:

    The following features are missing: Pseudo 512 SNES horizontal resolution (no games are known to use this)

    Jurassic Park and Kirby's Dream Land 3 use this feature for tinted transparency.

    Perhaps if the developer chose x86 ASM instead of C++

    Then it would require megabytes upon megabytes of :i386 libraries to run on an x86-64 operating system, and the emulator would itself have to be run in an emulator on ARM or any other non-x86 platform.

    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.
