Hey furntree! Great job on fiddling with this. I’m in a similar position where input lag is killing the experience for me (getting a 7 frame lag on the NES/SNES cores (plus the 2 frames my TV adds!))

Any chance you could upload an image of what you’ve got working so far? I’m curious to know if the input lag can be reduced to a level that I would personally find acceptable. 9 frames just isn’t good enough for me. If I can get it down to 2 (plus the 2 from my TV) I’d be more willing to put more time into getting RetroPie up and running. As it stands, the stock image/script installer just don’t cut it imo.

Don’t get me wrong, I appreciate the effort that’s gone into this project and understand that the technical problems are actually related to Libretro/RetroArch, but I don’t really want to invest more time into this if it isn’t possible to reduce the input lag.
