No.
You have to have seen or caught every Pokemon in the game
you need to have seen all the Pokemon in the regean first
The credits roll after you beat the Elite Four. However, I would classify the game as being completed after you have seen all of the pokemon in the Sinnoh Pokedex and the National Pokedex.
go use fly after you have seen or caught or somehing but it has to have seen then fly to home go to the proffeser then show him your pokedex then he gives it to you hopes this helps ;)
Once you have seen every Pokemon in the Sinnoh region go to sandgem and talk to the professer-he gives it to you and professer oak comes along and updates your pokedex into a national pokedex
Number 111 on the sinnoh poke-dex is garchomp which can be seen in Cinthia's party in Pokemon league. In the national dex it is rhyhorn which is in victory road and stark mountain.
Well, no.1 option is to go to www.pokemon.marriland.com and look at the pokedex there or, over a while I will place the names of all I have seen/court. (I have seen the whole pokedex of Shinno but not the extention ones.)
You can't see palkia on Pokemon diamond unless you trade. However, it will be added in the pokedex after you've seen dialga and visited the elder of Celestic toen. She will show you a picture of palkia.
To catch Porygon in Pokemon Diamond you need the National Pokedex. After getting the National Pokedex go to Trophy Garden in Route 212 and talk to the owner. When he says he has seen a Porygon it will now appear in the Trophy Garden.
To get the national dex, you first have to have SEEN every Pokemon in the regular pokedex. Then talk to Prof. Rowan.Then Prof. Oak will barge in say some stuff then he upgrades your Sinnoh pokedex to the Nationaldex
You can find Dawn at Professor Rowan's research lab in the Sinnoh region.
