The emulator reads the game’s state and continuously compares them with the bunch of trophies that come along with the game. The PlayStation 2 did not had a trophy system back then but the emulator intelligently reads the game’s state and based on some internal variables, a trigger event happens. Modern games are programmed with an event base model which means certain things should happen before the event is fired to initiate a trophy. The emulator also comes packed in with a smart logic for trophies implementation. Since the Emotion Engine is being completed emulated by software, the solution possibly has less dependencies on the PS4’s on-board CPU processor. After all, the existing architecture needs to understand the draw function calls from the emulator to the PS4’s GPU. Given that Sony uses its own custom graphics API which has evolved over the last many years and they have already done this kind of stuff before, it must have made things a bit easier. The Emotion Engine uses a 128 bit SIMD and integer registers which can be easily handled by the x86 architecture given that 128 bit SMID instructions were already present on x86 way back in the late 1990s. 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.
