We can’t say what kind of challenges the development team must have come across to implement the emulation but we certainly think that the simplified x86 architecture must have helped matters. So the main challenge for the development team must have been to emulate the Emotion Engine CPU and make it compatible with the existing unified memory architecture. PlayStation 4 features a 2 gigabit of SDRAM which is mostly used for managing background downloading and compressing shared videos, and an Audio DSP which is based on AMD’s TrueAudio technology. The Emotion Engine CPU was the state of the art processor developed by Toshiba and Sony but for a more general overview, check out the screenshot of the architecture above:Īll the essential components besides the Emotion Engine are already present on the PS4, although they are obviously much more advanced now. In order to understand how emulation works, one has to look back the architecture of the PlayStation 2.

So as you may have already guessed by now, the PlayStation 4 uses software emulation to run Sony’s old PlayStation 2 catalog of games. Later on Sony completely removed hardware emulation and opted for software emulation by allowing players to buy PS2 games from the PlayStation Network store. architecture which allowed players to play most PlayStation 2 and PlayStation One games. The first batch of PS3 SKUs actually had the original PS2 Emotion Engine CPU embedded right into the console’s complicated C.E.L.L. Most manufacturing companies opt for a software emulation or in some cases, a more expensive hardware emulation. The bigger question right now is: How does emulation work on the PlayStation 4?Įmulation of older games on new consoles is not a new idea. However, it seems that Sony will be taking a different approach regarding the business model of making their older catalog available for the PS4 by charging for digital downloads compared to the free model that Microsoft opted for.

It’s an interesting strategy by the Japanese company which is most likely a reaction to Microsoft’s support for Xbox 360 games on the Xbox One via the backwards compatibility update that was released for free a few days ago. A few days ago Sony officially confirmed emulation of PlayStation 2 games for the PS4.
