Where have you added this? What guide did you follow (if any) and have you posted the config to pastebin so that it can be inspected?
P.S. I have just read through some of your previous posts since July and numerous people have continually pointed you to read the https://retropie.org.uk/forum/topic/3/read-this-first yet it looks like you still haven't done so. Don't be surprised if your posts go ignored if you continue to ask random questions without providing the required information or taking the time to search this forum first.
