Banjo-Kazooie: Grunty's Revenge is the first Banjo-Kazooie game not to be released by Nintendo. However, it is the last game in the Banjo-Kazooie series to focus on the platforming elements. Also, the game was not released in Japan, for some reason.

Debug Menu

In the US version (internal build number 0.42.75), enter the following codes on a Gameshark:

83002AA8 9DD9
83002AAA 0800
74000130 00FF
83002AA8 0BA9
74000130 00FF
83002AAA 0801

Then, press L, R, and Select while playing the game to bring up this menu:

The top part of the menu contains the following strings:

  • A version string
  • A string telling whether or not the whole game is unlocked
  • A string telling whether or not God Mode is enabled
  • The map the player is on (using the map's internal name)
  • The player's coordinates on the map

The working options on this menu are:

  • Warp Map - Warp to a level in the game
  • Debug Info - Toggles the display of various types of debug info displayed on the bottom of the screen
  • Cheats - Unlock the Game (all levels and abilities are unlocked), God Mode (auto-refilling health), and Full E/F (gives the player all the moves)
  • Transform - Select from one of five transformations (Banjo, Mouse, Candle, Tank, Octopus)

Hidden Objects

Gold Feathers at Banjo's House

Background layer 2 deactivated with VisualBoyAdvance.

At Banjo's house, some Gold Feathers can be seen by deactivating the top background layer (See lower-right corner in picture). It's possible that the present Spiral Mountain could once be explored as a regular level at some point in development, and not just the past version. Notably, if the player were to hack Banjo into this area, the feathers can be picked up like normal.

Misplaced Text Box

BKGR-hiddenoval.png

At the bottom left of the starting area in Spiral Mountain is a misplaced text box that can only be seen by disabling background layer 3.

Unused Graphics

Hmmm...
To do:
Add unused graphics for Yum-Yum, Gruntling Commander, Banjo and Kazooie flying, Boggy, and the chained Breegull. All of these are currently on TSR.
BKGR-BossPlaceHolders.png

A boss placeholder sprite used in the prototypes for bosses that weren't implemented yet.

BKGR-nintendologo.png

Near the graphics for the Rare and THQ logos is the Nintendo logo which was used in the prototypes.

Region Differences

Hmmm...
To do:
See if there are other regional differences
U.S. Europe

For the opening sequence, the story text in the U.S. version has the text shifted over the left, while the European version centered the text.
