for some crazy reason I got a message asking for a password in the setup, it was at the point where I am trying to setup symlink I tried to ignore this but it just says password incorrect, I then ran root and retyped the instructions but when I now type mupen64plus I get a "not found" error. could it be that I typed the wrong location in and now it can't find the file? even when Im in the .mupen64plus folder and I can see the mupen64plus file it still says "mupen64plus not found". Any ideas on how I can redo this step?
