The Japanese narrator starts off as they do at the beginning of the series and movies by explaining what 'Pokémon' stands for. The English dub skips the 'Pocket Monsters' explanation part.

English Narrator: The Pokémon world!
Japanese Narrator: Pocket Monsters, "Pokémon" for short.
(ナレーター): ポケットモンスター　縮めてポケモン。

A poster above Satoshi's bed in his room in Masara Town, Kanto region says: "Pokemon Monster Ball Get". Anime Language transcriptions:

	GET

Sakaki in the Japanese original specifically states that the plan is to 'take over the world'. Giovanni in the English dub just states that the Unova region is vital to completing Team Rocket's plan.

Giovanni: A major new stepping-stone that will move us toward the successful completion of our plan.
Sakaki: This place is to become a new foothold in our plan to conquer the world.
（サカキ）: 我がロケット団世界征服計画の新たな足がかりとなる場所だ。

Isshu-chihō (イッシュ地方) is the name of the region in Best Wishes. The rest of the decryption seems to be animators notes. It also refers to ANA7 and our loving friend Sonansu! The animators note also makes a Japanese airline reference reminding that its not JAL but instead ANA. The caption for the mountain picture is a reference to Heidi, Girl of the Alps (アルプスの少女ハイジ).

The English dub added an extra line for the Air Traffic Control man.

Air Traffic Control: You are cleared for landing.

One frame was not painted correctly during a scene just after Zekrom leaves. Pikachu's ear is missing the black tip.

The reference to the thundercloud being like god's eye (神の目) was removed from the English dub.

Professor Juniper: From within its thundercloud, Zekrom watches over people and Pokémon.
Professor Araragi: The huge thundercloud is a god's eye protecting people and Pokémon.
（アララギ）: 巨大な雷雲は人とポケモンを見守る神の目。
