UPDATE: Here's what I found online.
Launch the game: Start the Ratchet & Clank game on your PlayStation console.
Access the options menu: Look for the main menu or pause the game and navigate to the options or settings menu. This can usually be done by pressing the "Options" button on your controller.
Find the language settings: Look for a section in the options menu specifically related to language or subtitles. It may be labeled as "Language Settings" or something similar.
Change subtitle language: Within the language settings, locate the subtitle language option and select it. Choose the Dutch (or Nederlands) option for the subtitles.
Confirm and save changes: After selecting the Dutch subtitles, navigate to the confirmation or save button in the options menu to apply the changes. The game should now display Dutch subtitles.
Verify audio language: Check if the game also allows you to change the audio language. If it does, locate the audio language option and select English. This way, you will have Dutch subtitles with English audio.
Resume playing: Once you have made the necessary changes, exit the options menu and resume playing the game. The subtitles should now be in Dutch, while the audio remains in English.
