I am currently working on an offline pokedex that will have all the pokemon from red blue and yellow all the way to X and Y.
This pokedex has everything hard coded in it so you won't have to be connected to the internet to use it.
I will be releasing the demo when I get a little bit more of it finished. Sadly for everyone, the demo will only have the first 20 pokemon. So from Bulbasaur to Ratacate.
