no there is not i have checked extensively with no good results.
The good news is that you don't have to catch all the Pokemon, but you only have to see all the sinnoh Pokemon to get the national dex:)
there is no cheat
the best cheat is from action replay its getting the manaphy egg use Pokemon ranger or action replay hope i helped
by getting the national pokedex.
Don't cheat, train!
this site has a complete diamond/pearl walkthrough, info on every Pokemon in the national dex and where to get them all and how to evolve them, and other great stuff! check it out! www.Pokemon.marriland.com
To my opinion, the best cheats are either the Shiny Pokémon cheat, the 999 Master Ball cheat, the Azure flute cheat which leads to Arceus, and the National Pokédex cheat.
no, you have to cheat it
Yes there is a cheat forPokemon pearl and it is called action replay.
no, they're only available in pearl
no there is not a cheat for that but there are other cheats
No, but you can do it without a cheat.
