if you want Entei in Pokemon Diamond/Pearl you'll need a Pokemon FireRed/ LeafGreen that you started out with Bulbasaur. In FireRed/ LeafGreen if you started out with Bulbasaur [Grass-Poison] after you defeated the Pokemon and if you run into Entei in the wild capture it and migrate it into to Pokemon Diamond/Pearl through Pal Park. If you want to migrate in Diamond/Pearl you'll need to see all 150 Pokemon yes both Dialga and Palkia. You'll see Dialga in Pearl from an elderly woman who's shows you its picture and the same with Palkia in Diamond from the same elderly woman in Celestic Town. This adds its data to your Pokedex and less Pokemon to see in Diamond/Pearl.
You can get the Happiness Checker Poketch App by talking to a woman in Eterna City's Pokemon Center. This app allows you to see how much your Pokemon likes you.
You can't catch Dialga in Pokemon Pearl; however, you can see it. Go to Celestic Town, and go to the northern house. The woman inside shows you a picture of Dialga. This counts as being "seen" in your Pokedex. In Pokemon Diamond, it will be a picture of Palkia.
