PS1/PS2 games heading to PlayStation 4
Source: titles running under emulation, HD visual enhancements in development.

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.

就好像现在破解的PS3可以随便玩PS2的ISO一样，PS4也是毫无压力，而且目标是可以像PC模拟器一样提高游戏的分辨率至HD

不过PS3的游戏目前仍然需要云方式来运行

我一直以为这消息是个人都知道了

意义不大，啥时候psv可以玩ps2游戏就真牛逼了。。。。。

意义不大，PS太古老了没什么人感兴趣，手机模拟器都烂大街了。PS2上的好游戏老索索早已经在PS2上玩过了，从PS3过来的年轻索索也不可能忍受得了HD化后的老游戏画面。

期待，希望把全部的ps1/2的游戏数字化。

都是叉86  两台机器都破解装win764位

破解了入三台。

对老玩家来说，PS,PS2上想玩的肯定都玩过了。
对新玩家来说，PS,PS2上的游戏应该没什么兴趣吧。

ps4要是破解了，国内真没x1什么事了。

希望PSV能玩全部PS模拟器游戏啊。。。
希望PS3能玩全部PS2模拟器游戏啊。。。
希望PS4能玩全部PS3模拟器游戏啊。。。
以上都不要以云游戏方式啊。。。
国内网络伤不起啊。。。
