Check the specific game first
On the PlayStation Store, an unsupported game is marked as only available on PS4. Game Boost applies to select supported games; its presence cannot be assumed based on the age of the game. Write down the title, edition, and format of your copy. The standard game, re-release, and stand-alone remaster may have similar covers, so compare the product page, not just the title in the search. First answer the compatibility question, then check the access rights to the desired copy.
Launching disc and digital copies
For a compatible PS4 disc, you need a PS5 with a disc drive: insert the disc, install the required update and open the game from its game hub. The disc must remain inside during play. Look for a digital copy in the game library and choose to download. PS3 discs are not supported. If you have a Digital Edition, check the exact model and disc-drive compatibility in Sony’s separate support article: the Digital Edition name alone does not describe all generations of the console. Don't buy a digital copy just because you have not yet checked whether your original disc can be used.
Check controls and launch results
Supported PS4 games can use DualSense and DUALSHOCK 4 controllers; PS5 games require DualSense. Check the manufacturer’s compatibility information for specialist controllers. After installation, check that the correct version of the game is open, then enter a playable scene and compare the buttons with its settings. If the problem appeared before startup, write down the message and installation method; if after launch - the scene and the controller used. This information helps differentiate a product incompatibility from a separate access or control issue. We did not hardware test every game.
