Sony Patent Causes PS5 Backward Compatible Rumours

  1. 1. Will The PS5 Have Backward Compatibility?

Recommended Posts

A recently published or republished patent by Sony  titled "Remastering by emulation" has managed to causes rumours and speculation that the PlayStation 5(PS5) will have Backward Compatibility, here is some information:





Each asset such as a texture called for by legacy software such as a legacy computer game software has a unique identifier associated with it. The unique identifier can be rendered by imposing a hash on the asset, and then the asset stored with its identifier in a data structure. An artist remasters the textures for presentation on a higher resolution display than envisioned in the original software, and stores them back in the data structure with their identifiers. The original software is then played on the higher resolution display, with asset (such as texture) calls being intercepted, identified, and the data structure entered to retrieve the remastered asset having a matching identifier. The remastered asset is then inserted on the fly into the game presentation.


I am not sure that this patent has anything to do with Backwards Compatibility in the traditional sense, where you stick a disc on a previous console in the new console and it plays, this seems to me to be something similar to how PS2 games are played on the PS4 at present, the game is packed with higher resolution textures and an emulator.(Check edit)

 I would love to see the PS5 able to play games from all the previous PlayStation's, however i do not think Sony would commit itself to such a task, instead they will just keep re-releasing old games with higher textures that can look decent on a 1080p+ TV as well as adding trophies, i really do not think we will ever see any future consoles from Sony having Backward Compatibility.


I have added a poll, participate in it :)


Here is the patent


Thanks @zecoxao



I have been corrected by developer @Zer0xFF on the line i have put a strike through above, this is what he said:



false, this is NOT how it works on the PS4, the PS4 is straight up emulating PS2 games, with increased resolution, which is a feature of how shaders work


what that patent saying it can detect textures and assets are replace them, the closest thing we have to that is FFXII remaster
