[Rumor] Is Sony sneakily removing PS4 backwards compatibility from PS5?

    “it would not be the first time Sony make promise on backward compatibility that they cannot keep”

    Remember OtherOS….

    I’m more in the camp of the people that think that PS4 bw compat WILL be enabled and working but since it’s software based (low level emulation), only a set of games will be fully supported. More or less like the Xbox 360 compat: they gradually tested and supported more games as they went along and now almost every game is compatible.

      How can it be software based? How can it be emulation? is the same architecture x86-64 by the same company, is not like the Xbox that used a pentium and nvidia while the xbox one uses amd. The only issue would be if sony were to not use FreeBSD as the OS but even then. The only issue would be if for some reason the games interacted directly with the PS4 Hardware instead of by libraries, and they were doing something that for some reason is not supported in the PS5 HW (which again, is same architecture), which AFAIK they dont.

      The only reason to not be fully supported is by having a blacklist/whitelist of software playable

        Emulation will have to be done for the new syscalls and new graphics API. Of course some work will have to be done on that.

          No it dont MS have shown what sony are saying to be BS as they using similar tech and have shown that the new xbox will work with all last gen xbox games

          Dont care I have 2 ps4s.

          Saying it “will have to be done” is a huge, HUGE oversight. Sony, having developed a new OS layer on top of FreeBSD and a new graphics API, can just gate an entire compatibility mode through a system flag that would be called upon booting a PS4 game. It’s not a big deal when moving across x86 platforms and there’s a very slim chance to have a whole new graphics API instead of direct Gnm/Gnmx updates.

          AFAIK The chip has a legacy mode that is fully compatible with PS4’s one and Mark Cerny explained it (instructions, clocks etc). At most you need a secure container for the ps4 kernel, so no exploit of the old system would affect the new one and the technology is already mature enough.

          Now… whether the PS5 will support PS4 or they will force you to buy the old console/PSNow as well or a second copy of the game for PS5 – this is business decision, nothing to do with what can and cannot be done.

    No backwards compatibility, no buy. I’m tired of their ***. I can make do with pc and switch.

    If the ps4 and ps5 are both x86 based then why would emulation be needed for backwards compat?

    • anon

      If they change the underlying OS it will require at least translations to the new APIs. Simillar with Windows and Linux, they both run on x86 but they can’t run each others’ software without implementing a compatibility layer(WINE) or running an instance of the other OS(WSL)

    No they aren’t, they just hate the thought of having to do it.

    I’ve never understood an individuals way of thinking when it comes to “no backwards compatibility, no buy.” I buy a new console because I want to play the new console’s games. Backwards compatibility, to me, has always just been a bonus. Not a deal breaker.

    Most likely that backwards compatibility is going against them securing the system from exploitation.
    It leaves some doors open.

    Remember WiiU anyone

    They probably just removed that sentence for clarity. It draws too much focus away from the fact that it’s a new console that will play new games.

    I agree that its questionable why they removed that sentence from their website, but they’re clearly not removing backward compability as a whole from the PS5 😛 Why would they do that after speaking on how important that it is?
