Sony Hints at Backwards Compatibility for PlayStation 5

Sony Hints at PlayStation 5 Backwards CompatibilitySince the debut of the PlayStation in 1994, Sony has amassed a massive library of games on its various consoles. Problem is, software from previous PlayStations ain’t always backwards compatible on newer models.

But there are hints that the next PlayStation, the PlayStation 5, may run the entire mighty 20+ year old selection of games.

The latest hint comes from a patent filed by Sony titled “remastering by emulation.”

In short, the patent describes remastered assets being inserted “on the fly” into original software to bring it up to speed for HD displays.

I, for one, hope this comes true, because it’ll mean I haven’t been hoarding all those PS1 games in my mom’s basement for all these years for nothing (sorry mom!).

Here’s the full text of the patent summary:

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.
