After you defeat the Elite Four go to sandgem city and talk to professor rowan and then professor oak will come they will talk then give you the nationaldex
You have to catch every poke on in your normal pokedex
no
you get it when you see every single Pokemon in Diamond or Pearl, then go and speak to proffeser rownan
catch Dialga and Palkia this is incorrect, you finish the game when you have completed both pokedex + nationaldex.
Migrate it(Nationaldex needed)First you will need Emerald.Then catch celibi on Emarald and then migrate using palpark.
When you complete the first pokedex you go to the professor's laboratory (I think that talking by the computer on hospitals also works)and he will give it to you.
get nationaldex go to the route by were the psyduck were (ahead) and usepokeradar and find one no you can only find bagons in Pokemon perl version
nothing. it just woudn't show in your pokedex intill you got the natational one.
No I can prove it too I battled a corsola (unseen at the time) looked in my Pok'edex and no Corsola to be found
No, you have to trade them from Diamond/Pearl or Platinum. You can also get it from a poke walker route called Tree house. (15,000 wats to unlock)
You can't. You have to get NationalDex and then talk to Bebe. She will give you a free eevee, though I think it only works once
