Sony is bringing modern convenience features to PlayStation Classic games on its new PS Plus service.
Today Sony announced 119 games that will be available on its new three-tiered PlayStation Plus service (check them here). Original PlayStation and PSP games will actually have new features like save states, rewind, a new UI, and even FPS boost and resolution upscaling features similar to Microsoft's built-in backwards compatibility enhancement tech.
"Some titles that will show improved frame rates and higher-quality resolution compared to their original launch versions. For select original PlayStation and PSP classic games, members will also enjoy a new user interface with menus that allow you to save your game at any time, or even rewind the game if you want a do-over."
Sony is careful to say that only select games will make use of these features and not every title will be supported.
Remember that PS1 and PSP game downloads are only available to PlayStation Plus Premium subscribers.
