Backwards compatibility is coming to PlayStation 4, and PlayStation Now is only part of the story. A well-placed source working with Sony's streaming service reveals that only PlayStation 3 titles are currently scheduled to use the "gameplay over IP" cloud service. PS1 and PS2 titles are set to follow the more conventional route of running locally under emulation on Sony's latest console - but with the possibility of HD visual enhancements.

While Sony effectively phased out hardware emulation of previous platforms during the early stages of the PS3 era, it has worked consistently on opening up the PlayStation back catalogue to publishers via software emulation and PSN downloads. Internally, PlayStation 3's firmware contains emulators for PS1, PS2 and even the handheld PSP, while Vita is capable of running PS1 and Vita titles virtually flawlessly using the same technology. In short, there's a proven codebase that can only get better for the vastly more powerful PS4.

Our information suggests that the same internal emulator strategy is planned for PlayStation 4, and we understand that Sony is actively pursuing the ability for older titles to run without the blurry upscaling seen on PS3, suggesting that native HD resolutions are being targeted. Assuming this intention carries through to final code, we'll be seeing an effect similar to the resolution scaling seen on unofficial PC emulation of Sony's consoles, as well as a great many of the "HD remasters" we saw on PS3 - where original assets were rendered at a higher resolution, often without any actual remastering at all.

Sony's use of emulation as opposed to PlayStation Now streaming is an interesting decision - and the right one for enthusiast gamers. Running code locally provides a superior experience in terms of both input latency and image quality, and owing to the bandwidth requirements of continuous gameplay streaming, a single download could actually work out better economically for the platform holder. However, anything that can be run on PS3 can also operate on the PlayStation Now servers, so theoretically there is no technical reason why PS1, PS2 and PSP titles running on the existing, upscaling PS3 emulators couldn't be added to the streaming service should Sony see fit - though HD resolution scaling would most likely be off the table in those circumstances.

我估计日后还能兼容PS3，只不过现在因为PS3还没退市所以不能说

兼容PS3才有意义，谁还会去玩PS1•2的游戏呢？

该用户已被禁言

慢慢做吧……等着NEW呢~

PS2的游戏HD化后画面还可以的，PS1就算了吧

向下兼容吧，记得再调整一下语序。你平时也那么说话？翻译真轻松啊。

PS1 和PS2  没啥 大意义  要奸容 PS3才是王道

为啥是向后兼容 不应该叫向上兼容灭

backward compatibility是老外的习惯用法

ps3模拟ps1都玩不下去了，ps4模拟能有什么区别么。。。
