The only way besides using a cheating device (eg. GameShark), would be to save just before initiating a battle with said Pokemon and keep battling it and resetting until you encounter it as a shiny (this would only work with Pokemon you walk up to to start a battle, like Kyogre or Groudon).
The chances of a Pokemon being shiny are one in 8192, so you may be there a while. Good luck, you'll need it.
Get out you stupids! I'm better! You can't get a shiny Pokemon in emerald! Except for me! Hahahahahahaha!!
sorry but there are no shiny Pokemon codes they do not exist right now
Internal battery has no effect with shiny pkmn
No matter what Pokemon it is and if it is shiny it will stay shiny if you trade it or migrate it, trust me i know i traded my shiny banette to Pokemon xd and its still shiny.
There isn't any shortcuts for shiny pokemon, it all depends on luck

There is no Blissy Pokemo on Emerald.Therefore there is no Shiny Stone.

You can use gameshark to create shiny pokemon, but I don't prefer cheating.
