To get all three sinnoh starter Pokemon, you need 2 Pokemon sinnoh games & two ds's. you also need to be able to trade. on your platinum, say you picked turtwig first, go to your other game on the other ds & pick chimchar. put up a trade for a easy Pokemon to catch, eg bidoof then on the platinum game trade it other. you will then have turtwig & chimchar. do the same for piplup.
Save in front of where you get your starter Pokemon, then reset until your chosen starter is shiny.

Begginer Pokemon can be obtained in three ways: -At the beginning of the game when you choose your starter Pokemon -Trading with other trainers locally or over the Gts -Or breeding the evolutions ofthe begginer Pokemon with the same Pokemon in there egg group.
You can't get Thunderus in Pokemon Platinum at all. By then when Pokemon Platinum was made, no one knew that Pokemon Black and White were going to be made.
you see all the Pokemon in platinum and trade from your other games like emerald, blue, fire red etc and that is how you find all Pokemon in platinum.
almost all.
there is no code.
