PS5: backward compatibility pushed to the PS1? This patent suggests it

Sony is still working on a way to deliver on its PS5 backwards compatibility promise. Indeed, Mark Cerny, the architect of the next-gen console, and David Simpsons, lead programmer at Naughty Dog, have just filed a patent for a new system centered around backward compatibility.

In the months leading up to the PS5’s release, fans were crossing their fingers for wide backward compatibility on Sony’s latest console. It must be said that the competition has been strong, since Microsoft supports no less than 700 games from the Xbox 360 catalog and Xbox on Xbox Series X and Series S.

Ultimately, players’ hopes are swept away. The PS5 will offer backwards compatibility on 99% of PS4 games, and PS4 only. Indeed, 10 rather anecdotal games are falling by the wayside and cannot be launched on the PS5. Since the console came out, but despite everything, Sony has shown on several occasions that it has not dropped the case regarding backward compatibility.

Sony continues to work on Playstation backwards compatibility

Indeed, a first patent filed in March 2021 has put the subject back on the table. The documents described a method for assigning trophies in emulated ancient games. And justly, another patent surfaced this Friday, January 14, 2022. This patent, dubbed “Backward Compatibility Though Use of Spoof Clock and Fine Grain Frequency Control“, was submitted by Mark Cerny, the architect of the PS5, and David Simpson, lead programmer at Naughty Dog, Sony star studio behind The Last of Us and the Uncharted saga.

As the title suggests, this patent describes a method that would reproduce the clock frequency of old consoles and reach the number of cycles performed by the CPU of previous Sony machines. In other words, this technology will allow the PS5 to run at a lower CPU clock speed or at least simulate it, in order to run PS1, PS2 and PS3 games.

Interestingly, the publication of this patent comes as several rumors point to the upcoming launch of a new subscription service from Sony. Designed as a competitor to Microsoft’s Xbox Game Pass, this Spartacus project would offer three formulas, and the most expensive would precisely allow access to PS1, PS2 and PS3 games. In fact, there may be a connection between this patent and this hypothetical new service from Sony.
