Making the Pokédex dual screen

Well I want to do is that when opening the Pokedex appears dual screen, but only to open the pokedex.
How I can do?

You can use Help-14's Pokedex, it goes Dual screen even if you use single screen, but mind this, the script may not work properly on v13+ so some amount of tweaks should be done to make it work properly on v13+ essentials.
