Go to google and type in Pokemon emerald secret word generator. Then you can customize your own wallpaper for the pc (it all depends on your trainer number)
Unfortunately, you can't get an Onix in Pokemon Emerald. To have your own Onix, you need to trade it from FireRed or LeafGreen. Hope I helped :)
