There are two ways:
-Once you have AT LEAST ONE Pokemon in every one of your eight starting boxes, eight more will appear. (this continues till the max. number of boxes has been reached).
-The second way is to simply fill your boxes to the max, then eight more will free up.
There are in fact over 9000 boxes in Pokémon Platinum.
you cant, after you've caught all that could fit, you have to release them in order to register more in your pokedex.
as many as you want until they fill your PC boxes!
Only in the pc boxes you can release them. All you have to do is tap on the pokemon then the release.
No. It doesn't exist but you can try and download a hacked version or even hack it yourself from a DS
In order to get all 24 PC Boxes to appear in Pokémon White, you need to put at least 1 Pokémon in each available PC Box and then log out of your PC and then back in.
they allow you to switch between your boxes with ease
There is no cheat in Pokemon to get additional PC boxes. Those who need additional space in Pokemon X and Y can use Nintendo's Pokemon Bank service.
The PC on Pokemon is a place where you can keep in a computer if you have 6 Pokemon in your Party. The more full your PC gets the more boxes you get.
Originally when you start Black or White, you'll only have 8 Boxes which is only enough to store 240 Pokémon however as you fill up the 8 boxes with only a minimum of 1 Pokémon, you'll get 8 more boxes added to your PC which will bring it to a total of 16 Boxes and then after you fill up the 16 boxes with 1 Pokémon each, you'll be given 1 final upgrade which will give you a maximum total of 24 Boxes, this will allow you to store 720 Pokémon in the PC.
In order to get additional PC Boxes in Pokémon Black and Pokémon White, you will just need to put at least 1 Pokémon in each of your current 8 boxes and then log out. Once you've logged back in, you will have 18 boxes, this process can be repeated once more until you have a maximum of 24 boxes.
There are in fact over 9000 boxes in Pokémon Platinum.
You first put 5 of your party Pokemon in your PC Box. Then you have to switch your remaining party Pokemon with another Pokemon from one of your PC Boxes. You have to have at least one Pokemon with you at one time.
you don't.
you can't catch more pokemon. you have to get rid of some pokemon.
where all your Pokemon are listed
put some Pokemon in your PC boxes, which is located in the Pokemon center. If you want to get rid of them FOREVER you can release them (you are only able to release them while you are in the PC boxes) hope this helps
