Sony has updated its certification process in order to ensure future PlayStation 4 releases are all compatible with PlayStation 5.
Eurogamer reports the platform holder has updated its developer documentation with a mandatory checkbox that indicates games have been tested for PS5 hardware compatibility.
The option was added at the end of April in a new version of the PS4 software developer kit, and applies to all games submitted from July 13, 2020.
The platform holder defines 'compatibility' as submission code that runs without issues on PS5, and provides the same features and modes as on PS4.
