I too added games when I did the dual boot... If you want to add a folder to the dual boot section with the 40 games you added you may want to look at ftp to the snes games section and use it's folder .desktop as a reference to simulate in the NES side of course the paths will be different... I personally uninstalled the dual boot part when I upgrade to 21f as I don't find my self playing the thoses games as much so I can't actually look to give u exactsthen you should read!
i want to create the folder manual with hand and without hakchi because hakchi has no access to the dual boot
