catch all the Pokemon in the pokedex you have, then talk to the professor at the beginning of the game (the one who gave you your first Pokemon)
no this guy is wrong. you have to have caught about 60 Pokemon and have traded with another game then go talk to the professer in the first town you start in and he will give you the national pokedex. if he doesn't you need to catch and evolve more Pokemon
only when you get the national dex on Sapphire version
You have to migrate six Pokemon from ruby, sapphire, or emerald in order to get into pal park. (after the national dex) Get the national dex. (before the national dex)
in ruby and Sapphire,they require more work than emerald version. so u must see all the Pokemon in the Sapphire and ruby gamesAnswerNo............No..............No.No.No.No!!!! To get the national dex, you need to trade Pokemon with fire red or leaf green and you will obtain the national dex automatically. You can't get the national dex if you don't have a link cable!!!! to trade Pokemon in sapphire to fire red. In one island give Celio the ruby and sapphire and voila!!!
tyranitar
national Dex have sapphire in and iron island
Pal park cannot be found in Sapphire. It is found in Diamond/Pearl after you get the national dex.
It's possible.
You complete your sinnoh pokedex, then go to your hometown and get the national 'dex then go to pal park and migrate pokémon from ruby, sapphire, leafgreen or firered.
You can only unlock the national dex that will add to the wild pokemon you see on the islands 4 - 8 , therefore you have to trade with saphire to get them added to your national dex
you get a diploma. One for your regional dex and one for the national dex. bonuses are also unlocked, differing by game.
its probably cause you don't have the national dex in emerald.
Both of these items can be obtained only after defeating the Elite Four, and obtaining the National Dex. The sapphire can be obtained in the Rocket Warehouse on Chrono Island. The ruby can be obtained from the post-National Dex area of Mt Ember.
