On the Pokemon emerald game you can make everyone shiny... It is just whatever your gender is the the only gender you see ( Except Pokemon with a high opposite gender rate 'like Ninetales') So the code for the shiny makes Your gender the Pokemon's gender; and the nature will be the last Pokemon's you've caught AND only that nature too. So does anyone have a gender change code! Please... (P.S.-- GAMESHARK codes are 11 digits long).
