PS5 system update fixes bug on PS4 disc installation

A new PS5 system update resolved an issue that caused PS4 game discs to attempt to install the latest generation version of a game, even if it had already been updated. The 20.02-02.50.00 update includes the usual vague disclaimer from Sony that “improves system performance”, but adds details of yet another specific change:

“The following issue has been resolved: the PS4 version of the game was sometimes installed from the PS4 game disc, even after upgrading the disc version of a PS4 game to the PS5 version.”

The problem affected games of several generations, such as Assassin’s Creed Valhalla, which was released on a PS4 disc and would then unlock a PS5 update when used on the latest console. The bug would cause the console to repeatedly try to install the PS4 version from the disc, every time it was turned on, even though the PS5 version was already present.

It closes another issue with PS4-PS5 updates, after fixes for a download queue bug that blocked PS5 version installations and a new warning system that shows if you are starting a PS4 game on your new console.
