Rumor Mill: Sony has missed the mark with the backward compatibility of the PlayStation 4 so far. However, a new patent filed by Sony has rumors that compatibility with retro games on PlayStation 5 may be emulated
A new patent filed by Sony may suggest that the PlayStation 5 has backward compatibility with all previous PlayStation Consoles – a feature that will no doubt delight PlayStation fans.
The patent is said to be designed by PlayStation 4 Lead architect Mark Cerny and would theoretically allow the PlayStation 5 to run software from older devices; H. PlayStation 4, PlayStation 3, PlayStation 2 and the venerable PSone. This is facilitated if the older software is misled into believing that it is running on the original device, which patent details refer to as "processor ID spoofing". This would mimic the behavior of older hardware to allow the older software to work with newer hardware. The PlayStation 3 architecture is known to be particularly difficult to handle, which is why Sony has come to a standstill with backward compatibility.
While the patent makes no specific reference to the hardware, a recent Reddit thread cites sources that speculate the patent The application is intended for the PlayStation 5. It is also worth noting that the fact that a company submits a trademark does not mean that it will be published soon.
We had previously reported that the PlayStation 5 could be announced at E3 in 2020 and the console is said to be used with an 8-core Ryzen CPU and a custom GPU based on the AMD Navi architecture. It is expected that the PlayStation 5 will cost up to $ 500, while Sony has reportedly moved the first generation development to the next generation platform.
