Contrary to Microsoft’s strategy, sony no longer made backward compatibility a priority since the PS3, even though the PS5 is able to play the majority of PS4 games, and even boost them in certain specific cases. But that could be about to change if we are to believe a patent that has just been approved, and which was filed by the manufacturer last year, with Mark Cerny (architect of the PS5) leading this research.
Backward compatibility at the heart of a new patent
On this patent, relayed by GameSpot, we can read that Sony is working on a technology which would allow current consoles to reproduce the internal functioning, and especially the speed of execution, of old consoles in order to run the games of the time. on modern machines. Because you should know that the architecture of each console is different, and that old games can have trouble running on more recent ones if the latter do not reproduce all the operating conditions of the original media.
Unfortunately, no conclusion is made by this patent, but it does indicate that Sony is working on this problem. This does not mean that we are talking about complete backward compatibility, since the patent makes no mention of the PS1, PS2 or PS3 (it simply speaks of slower consoles), and that we are still in the state theory for now.
Like many patents filed by Sony, we will now have to be patient to see if this will lead to something or not.
