In November, 2016 the first patent was filed by Sony, titled “Remastering by emulation.” GearNuke unearthed the original patent in October 2018 and the speculation began that gamers could soon “play our PS4, PS3, PS2 and PS1 games on the PlayStation 5.”
“Remastering by emulation” outlines methods for creating remastered versions of our favorite games through complex algorithms. The original patent hints that this will be possible for games with certain identifiers within their code, while games without these identifiers would run in their original graphic settings.
The new patent discovered recently, titled “Simulation of legacy bus operation for backward compatibility” – seems to hint at a method for simulating the communications of old Playstation consoles. The patent also explicitly names Mark Cerny who lead architect for both the Playstation 4 and the Vita.
This, combined with the information from the previous patent, is causing the internet to turn rumour into fact, however Sony haven’t yet made any official statements.
Although backwards compatibility has never been a huge selling point for me on any console, the idea of remastering games on the go is an interesting concept and could bring new life to some of PlayStations classic titles.
