Media: Sony requires developers so that all new games for PS4 are also launched on PS5

by

Eurogamer reports that on demand Sony All games for PS4 sent for certification after July 13 should be compatible with PS5.

The requirement is mandatory for all future patches and reprints, if the entertainment went to check after the specified date.

The Last of Us Part II And Ghost of Tsushima, Most likely, they do not fall under new rules, but the press reports that they will also work on Nexstgen. [Augmented at 20:35 Moscow time: Information about reverse compatibility Part II The boss confirmed Sony Interactive Entertainment Jim Ryan (Jim Ryan).]

U Sony A new requirement for developers has appeared – all games for the PlayStation 4 sent for certification after July 13 should also be launched on PS5. This is stated in the documentation for the partners of the platform holder, writes Eurogamer.

If you believe the journalist, at the end of April, a point appeared in the development sets for PS4, choosing which the authors of the game confirm that it is compatible with PS5. Sony promises to contact each studio individually and explain how to test the compatibility of entertainment with non -stgen.

The documentation states that the platform holder refers to compatibility. For the product to be considered compatible with PS5, it must work on a new console without malfunctions and offer the same set of opportunities as on PS4.

Cyberpunk 2077 starts on PS4 and other platforms on September 17, so the new requirements will probably affect her and her.

Besides, Sony identified her requirements for upcoming patches and reprints. If the studio sent a certification game until July 13, then the corporation will not require compatibility of updates and remasters. Nevertheless, support for compatibility "is strongly recommended". If the certification process was initiated after July 13, then all the following updates and reprints must maintain compatibility with the new prefix.

It is worth emphasizing that we are talking about the date of sending for certification, and not about the release date. Entertainment undergoes a check long before the launch, therefore, for example, "Ghost Tsusima", whose release will take place on July 17, is unlikely to fall under new conditions. However, according to Eurogamer, and the samurai action, and The Last of Us Part II Still, they will work on PlayStation 5.

Recall, earlier Sony assured that the company is already testing games with PS4 for reverse compatibility and identifying problems. The corporation expects the old entertainment launched on Necstgen will differ from the originals of a more stable personnel frequency and higher resolution.

Meanwhile, Xbox Series X seems to be not lagging behind the competitive device, or even ahead of it – as she said Microsoft, Her console from the first day will support thousands of games of the past generation. They boast of accelerated loading, improved graphics, HDR support and, in some cases, a doubled personnel frequency.

Launching new consoles from www.prime-slots-casino.co.uk Sony And Microsoft scheduled for the end of 2020. According to rumors, already on June 3, the Japanese company will show the first games for PlayStation 5.

May 29, 2020 Power Ranges: Battle for the Grid will be the first fighting game with a cross-play between five platforms

May 29, 2020 Sony will show games for PlayStation 5 already June 4

The best comments

And who to shift it to? Sonya herself will not cut the updates so that the game works normally on PS5)
They cannot get into the game code and redo something without the knowledge of the developer)

In any case, it was better than at the start of the PS4-there was nothing there, Cross-Bai is present in a small number of games and then only in the number. and physical carriers go only to one system. And now it seems like PS5 will read discs from PS4. Sonya formally formally on June 13, they are all responsible for the compatibility of new developments.

And yet. Will this support for "lifelong"? The first revisions of the PS3 launched games from PS2 from the disks, and then cut it out, leaving only a built -in emuls.

Yes, all games will have to work on the trail. generation. I see it like that. The difference between PS 5 and PS 4 is the same as, say, between Win10 and Win7. It is, but all the shortcomings can be easily corrected. Somewhere the call of the API function to change, somewhere else to correct. It is expected that all games will have to work because the API PS 5 did not change dramatically, but the relics were specifically increased due to iron. So from the developers you just need to launch your new game on PS 5 and fix errors if they are. In my opinion, this applies more to game engines, since it is they who interact with iron through the operating system through the API or directly if the API allows.

or, more likely, they were not allocated by resources for this, nevertheless, the decisions are made not by engineers but marketer, after engineers evaluate the labor costs of tasks, and I am quite sure that native reverse compatibility went under the knife in order to save.

But in one you’re lying) Windows 10 (which in your opinion must eat every game) does not do this.

Um, as it were, there is a “limit” of reverse compatibility, since its creation is also labor costs, and when writing a new OS, you need to make sure that the methods of “old API” will work, and usually support goes in 2-3 versions, reverse compatibility in essence guarantees that your software will work on the next version, but it does not guarantee the work of absolutely all subsequent ones. And the purpose of the purpose of reverse compatibility is that a “smooth upgrade” is possible, so that you do not immediately rewrite Softina as a new version of the OS out, at a graduation convenient for you. But this is relevant only if Sofin is “supported”, in the case of games where the dick was released and scored (the studio fell apart, sold their rights or even the Chort knows that) no one will update it, and it is pointless since the game has already been “sold”, why is it updated to new consoles. So the platform holder should bother with this, that is, Sony. They are so simple, 2 versions of the API for compatibility so that the outfits do not bother with the update at the moment of the joint of generations, and for completely old versions of the games (2 generations of consoles and older) stupid emulators (and the argument that the emuls 3 is pulled only a powerful PC not an option. Since these emuls were written almost on the bastard, and having documentation on the console that Sonya Emul can write normally).
In general, summarizing, I am sure that Sonya’s compatibility problems are not engineering, but marketing economic.

And they should not be imposed, the reverse compatibility should be at the OS level of the console, and the game should be sideways. OS is a layer between the game and the iron that “unifies” the method of access to the iron, and this is how the desktop OSs work, now no developer writes a code for writing a file for each individual hard drive, this is not his care, the OS has API to access the file system, it uses it under the hood, even on the sDA, even on the SDD, at least on a magnetic. Summer, at least for a punch card.
That is, for example, the current console API had "Writefile (F: File)" And his outfits were used, now a new console has come out and it has API "Writefilesdd (F: Array [byte])", If there is no reverse compatibility, then the inconspes should be replaced everywhere in their code Writefile -> Writefilesdd Otherwise, the game will not work. If there is reverse compatibility, then there should be a method on a new console Writefile which is marked as @Deprecated (outdated) which simply inside turns the input data of the method Writefile In these for calling Writefilesdd (File -> Array [byte]) and calls. The challenge of this method is not optimal, it creates unnecessary and unnecessary in terms of the productivity of the body move, but this is done on the side of the console and the developers of 100,500 games do not need to be redone for them to work on the new console. And in the end, old games work as they work, although they eat more resources than they should (which should be covered by the fact that the console is more powerful) and the new ones already use the current API and work as it should.
This is the essence of reverse compatibility, and Sony’s statement in this case is a bell that they have some kind of crap and apparently native reverse compatibility and does not smell like.

In words, this is of course simple, but apparently not everything is so simple in realization) otherwise everything would work for everyone) and everyone would be happy. We do not know how it works) Soniva engineers will clearly make us smarter) and if they could not realize (such compatibility as you described) then this is not so simple.
But in one you’re lying) Windows 10 (which in your opinion must eat every game) does not do this. Developers are not standing still, new drivers, etc.D are developed, and unnecessary functions are cut. Also on consoles)

Well, Sony did not surprise this decision, as if I was ready in advance for this. Well, even though they bend their line, the outfits will go to them anyway, because it is profitable

So the essence of the news is that the games will start. But now also patches should approach the systems on which the game is launched. This gives hope that network content will not be trimmed, etc. And the breeds are cuts – you can’t guess with them, xs how and what they will do. and xs how in the end all this will work.

Wait/hope/believe. We can’t do anything else

The corporation expects the old entertainment launched on Necstgen will differ in a more stable personnel frequency and high resolution

As I understand it, it will be compatible, just not every game will work.
In fact, the same garbage that was with the reverse compatibility of the Xbox One, there is a list of compatible games in which not every game is present.
Consider this approach “honest” reverse compatibility, or not this is already a separate question.

Something Sonya is not a flexion of the right, but to pay for such “voluntary-compulsory” transfers who will be?

Duck, what is the use of a disk reading if it has not muddied compatibility, all this will work only with chosen games

Sony has a new requirement for developers – from July 13, all games for the PlayStation 4 sent for certification should also be launched on PS5.

It’s not about patches and network functions, but about a simple launch, so if I head will do something to do something, then his game will not work for PS5

Karoch will not be any compatibility of PS4, simply in fact, the heads themselves should make ports on PS5, it was a shame, the same garbage was on PS3 when the games came to both PS3 and on PS4 at the same time in the end in the end

Another confirmation of the assumption that Sonya is not all right with PS5. Since now the compatibility is transferred to the developments. Something doesn’t work? Do the second version. Cost? And you will receive expenses due to non-principle in principle.
The breasts and publishers will not say thanks for such a setup, but they will swallow.
