Save state functionality has been part of the emulation scene for many years but it seems that it may make the move to consoles. A recent patent made by Sony outlines a future version of the PlayStation controller with a dedicated Save State button, per a legal document spotted on PatentScope by the folks at Tech4Gamers. An exact quote from the document states, "The user is able to enter the rewind mode from the live game play using one or more controller inputs to view recent game play (e.g. rewinding, fast-forwarding, playing, etc.) and returning to live game play afterwards." Keep in mind that not all patents become real products.
To users of various emulators, this descriptor of a "rewind mode" recalls the save and load state functionality common to those applications. Even Nintendo Switch Online's retro games support save states and brief rewind windows, these days. Instead of setting this functionality to a key bind like on PC emulators or a custom button combination like on Switch, though, Sony is looking to implement a dedicated button for this specific functionality, likely within immediate proximity to the D-Pad.
