With a few weeks to go before the PlayStation 5 arrives on November 19, Sony has outlined how backwards-compatibility of PS4 games will work with the new console.
The good news is that the "overwhelming majority" of the 4,000-plus games made for the PS4 will work on the PS5. However, there are some titles that won't work at all, and Sony has warned that some games may "exhibit errors or unexpected behavior" when played on the new console.
So far, Sony has published a list of 10 games that will not work on the PlayStation 5, but adds that the list "is subject to change and excludes demos, media, and non-game applications."
UPDATE: Since the list was first published, developers have pledged to patch the games so that they will work on the PS5. We have struck through those whose developers have said there is a fix in the works.
These games are:
Afro Samurai 2 Revenge of Kuma Volume One
TT Isle of Man - Ride on the Edge 2
Just Deal With It!
Shadow Complex Remastered
Robinson: The Journey
Hitman Go: Definitive Edition
Sony also explains: "Although many OS4 games are playable on PS5 consoles, some functionalities that were available on the PS4 console may not be available on PS5 consoles. In addition, some PS4 games may exhibit errors or unexpected behavior when played on PS5 consoles."
The company suggests that owners of PS4 games try them on their new PS5 and make sure they are "happy with the play experience" before purchasing additional content for those games.
It isn't all bad news though, as select PS4 games will actually look better on the PS5, thanks to the new console's Game Boost system, which makes older games run with a higher or smoother frame rate. Gamers will also be pleased to hear that PS4 accessories like the PlayStation VR headset, racing wheels and flight sticks will work on the new console.
Sony also asks gamers to use their DualShock 4 controller (the one that came with the PS4) when playing PS4 games on the PS5. The new console's DualSense controller isn't fully compatible with all PS4 games, and the older DualShock 4 controller doesn't work with PS5 games.
The company goes into more detail here on exactly what features of PS4 games will and won't work on the new PS5 console.
