Bionicle: The Game custom Bohrok fight (PS2)

This is probably my most complicated modification thus far. I recently learned how the game loads models, so I decided to experiment. I edited the file with the Bohrok Kal fight from Gali Nuva's level so that it loaded six Pahrak Kal instead of each individual Bohrok Kal. Then I replaced Pahrak Kal with the Pahrak from the cutscene in Kopaka's level. Obviously, you never fight Pahrak normally in-game, but since the Bohrok models are similar, it works without issue.
