You heard that right, the PlayStation 4 can now play the old PS2 and PS1 games.
This rumors about the PlayStation 4 that can play older games started when the Star Wars Battlefront PS4 limited edition was released, a special bundle code featured a select number of PlayStation 2 Star Wars games which runs more like an emulated PS2 game. This rumor was then confirmed by Eurogamer that Sony is indeed preparing an emulator of PS2 games for the PS4.
As the PlayStation Now streaming service only showcased a lineup of PlayStation 3 games, it shows that we might be seeing more PS2 and PS1 games from the PlayStation Network available for the PS4, as this was quoted from Eurogamer:
?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 PSP 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.?
From the looks it, Sony might be joining the Backwards compatibility trend as Microsoft leads the trend with their Xbox One that can play Xbox 360 games and the Nintendo Wii U having the capability to play old Wii games.
