SNES Mini style Rewind / Playback

Hi I’m making a topic to gauge interest in a feature like this and see if it’s something worth making a bounty for. I love the rewind system in Retroarch but ever since getting to use an SNES Mini the one thing piece of that experience that doesn’t feel matched in Retroarch is the excellent interface for rewind save states on the Mini that not only lets you rewind but also lets you play back your gameplay all the way to where you started rewinding from if you change your mind and decide there is nowhere in your rewind you wanted to jump off from.

IMO It’s a really fantastic way to handle rewinds and I wonder if something like this is possible in Retroarch, and if it is, if there are more people like me out there to generate a worthy demand for it.
