PS5 specs +Almost all of the most popular PS4 games will be playable on PS5 at launch

So no PS3/PS2/PS1 backward compatibility?

Backward compatibility broken down


It has been a while, but PlayStation is getting back to backward compatibility.

As a part of today's PlayStation 5 deep dive -- and it's a deep enough dive to blow out your eardrums if you don't have proper scuba equipment -- PlayStation master architect Mark Cerny confirmed that the new console will be able to play PS4 games at launch. Most of them anyway.

As Cerny explains, the PS5 "incorporates any differences in the previous console's logic into the new console's custom chips." That means that "the logic and features sets that PS4 games rely on is still available in backward compatibility modes." Cerny says this is the crux for backward compatibility on PS5, as opposed to adding the PS4 chipset into the PS5 chip which is "extremely expensive."

The result is that most PS4 titles will be playable on PS5 at launch. Cerny specifically mentions that Sony looked at the top 100 most-played PS4 games and "almost all of them" will be backward compatible. However, every title has to be individually tested because some "game code just can't handle it."

So I just need to understand. What about the digital PS2 games, etc., that I own for PS4? They’ll transfer over too?

Yeah i was a bit miffed if i'm honest. Is this gonna be like all the yearly FIFA's or something? That takes like 5 games.

He didn't give any clear answer to that question Ernst. But, i would expect they would work, at least eventually.

They can EASILY get B/C to work on the console, they just don't want to. If people with their PC can develop it for free, how couldn't a billion dollar company do it also?

They are already emulating the PS3 on PC.

I gather the ps3 is a bit like the saturn in being a bit of a conumdrum. I don't think it's easy. The xbox has always been pretty much a windows pc, so it was easier.

Honestly though, i personally don't care so much about backwards. All it does is let me shift my backlog to the ps5.
Also, remember that sony is selling a ps mini, so i am guessing that is why no ps1 yet, cause that is easy.
