Banjo-Kazooie: Grunty's Revenge

Prototype Info Prerelease Info

Unused Graphics#

To do: Add unused graphics for Yum-Yum, Banjo and Kazooie flying, and the chained Breegull. All of these are currently on TSR.

Boss Placeholder#

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

Nintendo Logo#

Near the graphics for the Rare and THQ logos is the Nintendo logo used in the prototypes. Nintendo owned the Banjo IP and was set to publish Grunty's Revenge before Microsoft acquired Rare in September 2002.

Boggy#

Boggy, a recurring character in the Banjo-Kazooie series, was meant to appear in the game.

Two animations of him idle and riding his sled. He looks more cub-like than his usual appearance, as Grunty's Revenge story is set in the past.

Boggy's sled appears red and in greyscale.

Gruntling Commander#

Early	Final

The Gruntling Commander has an earlier character design, appearing as a generic Gruntling with a fedora. The final character is purple with a skull-imprinted bucket helmet.

Flight#

Flight was meant to be an ability in the game, but was cut.

The flight pad with animated glowing.

A feather dropped while flapping.

Debug Menu#

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

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).

Unused Text#

Unused Languages#

While the American version has no way of switching the language, unused French, German, Spanish, and Italian translations are present in the ROM.

Hidden Objects#

Gold Feathers at Banjo's House#

At Banjo's house, some Gold Feathers can be seen by deactivating the top background layer (See lower-right corner in the 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#

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.

Misplaced Gate#

In Spiral Mountain Rise, there's a partial gate near the top of the level which is obscured by a cliff.

Regional Differences#

To do: See if there are other regional differences.

US	Europe

• In the opening sequence, the story text in the US version has the text left-aligned, while the European version has it centered.
• In Breegull Beach's pirate boss fight, the pirates take about a second longer to appear in the last phase of the fight in the European version. It's a clear oversight that is not present in the American version.
