Heya's.. Just wondering if anyone can comment on RPI4 performance running various emu's on retropie. Specifically in Kung Fu Master (if you guys remember this classic), when the enemy grabs you, you shake the stick left n right to shake em loose.. But I'm noticing a bit of lag between inputs and thus it doesn't work. Would an RPI4 be better for this ?? Or is it possibly the fact I'm running through the GPIO connectors using GPIOnext as the mapping software. Could a USB encoder eliminate this, or would it add more delay ? Cheers for any input.
