This video was captured by TylerL, a very valued member of our Libretro forums. In it, he compares a real NES running the game Super Mario Bros. to RetroArch running with 1 frame ahead.
You can see how Mario responds to a jump button press two frames later on a real SNES. With RetroArch and running ahead one frame, you can see Mario responding to the button press immediately on the next frame!
