Without a code: if you want the shiny starter, just restart OVER and OVER and OVER again till you get, it'll take around 5000 tries to get it right, about 8000 if you're unlucky. For legendaries, just save in front of them, and if they don't appear a different color/sparkle than normal, restart.
For random wild pokemon(like pidgey) you just have to keep running around in grass till u find one, and it may not even be a good one. I found a shiny caterpie in the viridian woods, but i just left it.
