How to play ps vita games on ps4
It is not possible to play PS Vita games on a PS4 console. The PS4 and PS Vita use different hardware and software architectures, and they are not compatible with each other.
However, some PS Vita games have been remastered or ported to the PS4, which means you can play an updated version of the game on the PS4. To find out if a PS Vita game has been remastered or ported to the PS4, you can check the PlayStation Store or do an online search for the game title.
If you want to play PS Vita games on a portable device other than the PS Vita, you can use the PlayStation Now service, which allows you to stream select PS Vita games to compatible devices, including the PS4. However, you will need a strong and stable internet connection to use PlayStation Now, and not all PS Vita games are available on the service.
