Taken from http://www.pokepedia.fr/ (Liste des Pokémon dans l'ordre du Pokédex National). They apparently took them from the French Mystery Dungeon games (Poképédia:Conventions de Style). This also corrects some typos.
The "he" characters were erroneously hiragana instead of katakana.
This appears to be the only way to make data access in eggs actually work, and is why the Platinum sprites are in pokedex/ too.
