No,but there are other cheats to do it.
NOTHING
First complete the sinnoh pokedex, 210 Pokemon
You complete the shinho dex first and then you get the national pokedex
That pokemon is Azumarill in pokemon platinum in the national pokedex
No.
complete the normal pokedex
No you dont, just the national dex
I am not going to list the list here, but here is how to open it online:1. In Google, type 'national pokedex platinum'.2. Press 'return' or 'enter'.3. Click or Double click on 'Pokemon Platinum- The National Pokedex'.Then the Sinnoh Pokedex will appear (even though it says National Pokedex, it's the Sinnoh Pokedex with the location and/or a trainer with the Pokemon)!
You do need the national pokedex for the Pokemon modifier. the Pokemon modifier uses the national pokedex numbes. you can not use the sinno pokedex.
yea look it up on youtube
you need to find 210 Pokemon to complete the pokedex
In the National Pokedex in Pokemon Platinum Mawile is Pokemon 303.
