So the movies are the same and the number of textboxes hasn't been investigated between different languages? I feel like in a game like this where there are so many textboxes, if there is a difference in the number of textboxes between languages, that could save quite a lot of time. If i understood correctly, i think it would be worth looking into whether different languages affect the number of text boxes.

Do we know which language/version of the game is the fastest. Like which language of text is the fastest? Is the NTSC version any different in speed to the PAL or NTSC-J versions? If we don't I might look into it.
