You won’t be able to visit the PlayStation Store on a PSP device any longer as Sony is set to shut it down by the end of March. However, you can still buy PSP software on other hardware devices.
PlayStation made the announcement on Twitter just a short time ago. They posted: “Update: Native PSP store to close on 3/31. Content purchases still accessible at store.playstation.com.”
A further announcement was made on the official website: “On March 31, 2016, the PlayStation Store for PlayStation Portable (PSP) system in the SCEA region will be closed. PSP system users will be able to purchase PSP content from the web-based PlayStation Store at store.playstation.com, and also access past purchases from the Download list on their PSP system. Users will continue to have the ability to make in-game purchases from their PSP system. Select PSP games are also available for purchase on the PlayStation®Store for PlayStation Vita system users.”
It’s been over ten years since the PSP first came out so it was only a matter of time until the Sony stopped supporting the device. Thankfully, games released for the console will still be available to purchase via other means. All you need to do is transfer the data.
