Making a NDS save backup homebrew (for CFW), help needed

As the title says, I'm making a NDS save backup homebrew (for CFW users only).

I've been able to dump my Pokémon Platinum save file knowing its size.
However I've no way to get or compute the save file's size.

Is there any complete NDS release list, giving the save file's size according to the GameTitle and/or GameCode out there?

Thank you in advance.
