During development, Banjo-Kazooie: Grunty's Revenge had a few changes from this 0.40.58 build to the final (0.42.75) build.

DifferencesEdit

Early Build (0.40.58)	Final Build (0.42.75)

As shown above, Nintendo was possibly helping in development of the game until THQ came in and took over. More differences:

• The debug menu can be accessed via pressing Select in all ways. In Banjo-Kazooie: Grunty's Revenge, it is not.
• The first piece of dialogue Banjo says ends with three periods instead of one.
• The copyrights screen is missing in the beginning.
• The four other language options redirect to English. The other languages were later removed in the North American version.
