Crash Debugger

Present in the game is a crash debugger that can be enabled by entering the cheat EPC in the Magic Codes screen. You'll also need a memory card plugged into the first controller. When the game crashes, reset the console and the crash debugger will appear. It'll quickly flip through four different pages automatically. Resetting the console again will boot up the game normally.

Sound Test

Diddy Kong Racing Sound Test.png

A sound test is accessible by the cheat code "JUKEBOX".

Unused Music

Early Crescent Island Theme

Sound test track 12 ("sea_2b" internally) is an early theme for Crescent Island but was cut in favor of a different song.

Unused Player-Select Theme

The character-select music changes its lead instrument depending on the character highlighted by the player. Within the track, there is a MIDI channel for a sitar lead which cannot be triggered under normal circumstances. This may point to Taj the genie being playable at some point in development as the track shares its sitar with his other in-game themes. Taj would eventually be made playable in the game's DS remake.

Unused Sounds

A sound effect for the pterodactyls seen throughout Dino Domain tracks. It seems that you were able to hit them at one point, but in the final game, you can't interact with them in any way.

A sound of a car driving by.

A voice clip of Taj saying "It's a balloon".

A sound effect likely meant for a menu.

An unused missile firing sound.

A sound for some kind of trap.


A couple of cartoon sound effects. It's unknown how they would've been used.

Unused Cheats

There are some unused/debug cheat codes in the game. Some are still enterable, others have been changed to a string of numbers, rendering them unenterable due to the convenient lack of numbers on the cheat code entry keyboard. To unlock all cheats, including the unused ones, use one of the below GameShark codes.

Version Gameshark code
U V1.0 810DFD9C FFFF
810DFD9E FFFF
U V1.1 810E031C FFFF
810E031E FFFF
E V1.0 810DFE2C FFFF
810DFE2E FFFF
E V1.1 810E03AC FFFF
810E03AE FFFF
J 810E17FC FFFF
810E17FE FFFF
  • High Speed Racing (code 1234567890): According to Nintendo Power(?) this would have increased everyone's top speed or maybe just done the same thing as the "No Limit To Bananas" code. It's listed in the official strategy guide, which helpfully doesn't give you the actual codes. It doesn't appear to do anything if enabled. Presumably it would have been an ordinary cheat code that could actually be entered at one point.
  • Print Coords (code 8846325012): Displays player 1's coordinates in the upper left corner of the screen.

Diddy Kong Racing Coordinate Display.png

  • ROM Checksum (code DODGYROMMER): Displays a checksum of the ROM when entered. (Appears to freeze for a few seconds.)

Diddy Kong Racing Checksum.png

  • Free Balloon (code EOLAOBFENRLONE): Exactly what it says on the tin: Every time you start Adventure Mode with this cheat active, a balloon will be added to the selected save file. This cheat can be entered normally but is never given in the credits. (Anagram of "ONEFREEBALLOON".)
  • EPC Lock Up Display (code EPC): If the game crashes, next time it's powered up it will display a crash report screen, which isn't very usable as it flashes through several pages quickly.
  • Control TT (code 1058732594) and Control Drumstick (code 8649305321): Actually implemented as cheats. When you unlock these characters, these cheats show up in the menu and can be toggled on and off.
  • Mirrored Tracks (code 0986754321): Appears to do the same thing as Adventure 2.

Unused Graphics

Dkr64proam64logo.png

A logo for Pro AM 64, likely from an early version of Diddy Kong Racing before Diddy was in the game.


DKR-ProAm64-Logo2.png

A second Pro AM 64 logo. There is no palette associated with the texture.


DKR-logo small.png

A small, earlier version of the Diddy Kong Racing logo. The palette here is guessed, as one couldn't be found in the ROM.
A German video of a prerelease version (labeled "1.964 VERSION") shows that it was once used on at least one of the arches seen throughout Greenwood Village.

Dkrkrunch.png Dkrbumperv.png Dkrtiptup.png yea Dkrtimberplaceholder.png Dkrbanjoplaceholder.png Dkrdrumstick.png Dkrpipsy.png

A series of icons used for an early version of the character selection menu. Note that icons for Diddy and T.T. do not exist, while Banjo, Conker, and Timber's icons only have placeholder text. These likely came from a period when the game was called Pro AM 64.


DKR-piratelagoon sign placeholder.png DKR-whalebay sign placeholder.png DKR-crescentisland sign placeholder.png DKR-treasurecaves sign placeholder.png

Crudely-drawn placeholders for the signs in the lobby of Sherbet Island.


DKR-twilightcity sign.png

A sign for Twilight City which matches those found in the Future Fun Land lobby. The sound effect for when T.T. says "Star City" is internally named TWILIGHTCITY, so this is likely an early name for that track.


DKR-ttdoor proto.png

An early T.T. Challenge door.


DKR-minimap 07.png DKR-minimap 09.png DKR-minimap 0B.png

2D image digits 07, 09, and 0B are unused HUD maps. The first map is maybe a early version of the map for either Greenwood Village, or Jungle Falls. The second map has not been found. The third map matches the first unfinished track in the second video below.


Dkr redpresent.pngDkr bluepresent.png

Presents hanging from red and blue balloons.


Hi!

A torch with googly eyes.

A bunch of development-related signs and symbols.

These icons show up on tracks when viewed in a setup editor as markers determining certain functions of the game, such as checking your progress on a track, silencing/enabling a MIDI channel, or warping the player to another area.


Dkr goldrarecoin.gif

A golden Rare coin. These coins were replaced with bananas to fit this game's atmosphere better, though these would have functioned the same.


Dkr rarer.png Dkr rarea.png Dkr rarer.png Dkr raree.png

Individual letters of "RARE". Likely used instead of the silver N64 coins in the Coin challenges.

Dkr 1player.pngDkr 2player.pngDkr 4player.png

Player selection graphics rendered in a strange font.


DKR AncientLakeSign.png

An early version of the Ancient Lake sign.


DKR BalloonMysteryDoor.png

A door with a silhouette of a balloon that has a question mark on it.


DKR BalloonCheckDoor.png

A door with a balloon that has a check mark over it. Most likely was used when you completed both races and coin challenges

DKR SpaceTree.png

A graphic that was likely meant to be used in Spacedust Alley.

DKR64-leefan.png

A fan blade intended for the air vents in Spaceport Alpha.

A sparkly purple gem.

Early Final
DKR64-tajpadearly.png DKR64-tajpadfinal.png

An earlier version of the Taj pad found in the hub world.

DKR64-wizpigmouthsequence.png

This texture is actually present in the map used in the cutscene that plays when you unlock the first Wizpig race but is never shown on screen. The map itself is also based on an earlier version of the hub world.

Unused Models

Sea Monster

DKR seamonster.png

An unused sea creature that most likely would have appeared in one of the Sherbet Island tracks.

Internally, it is assigned to two model IDs. ID 00F1 is named setuppoint and ID 00F2 is named SeaMonster. Many areas of the game, when viewed in a setup editor, display the setuppoint variant of the model. Judging from their locations, they appear to dictate where the players or NPCs such as Taj or T.T. will spawn.

Numbered Balloons

DKR64-1balloon.pngDKR64-2balloon.pngDKR64-3balloon.pngDKR64-4balloon.png

Four balloons numbered 1-4. They're only modeled on one side, so they were likely used in the character select.

Speed Signs

DKR64-30sign.pngDKR64-60sign.pngDKR64-100sign.png

Three speed signs likely intended to be scenery.

Early Plane Zipper

Early Final
DKR64-ringzipper.png DKR64-airzippers.png

An early version of the plane zipper.

Arrow

DKR64-animation.png

A multicolored arrow. It shows up in a level editor and seems to be related to animations.

Camera

DKR64-animcamera.png

A camera that is used in cutscenes to represent where the actual camera is. It's never visible in game because it's always off screen. It also appears in Jet Force Gemini and Mickey's Speedway USA.

Character Balloons

DKR64-badgerballoon.pngDKR64-banjoballoon.pngDKR64-chickenballoon.pngDKR64-krocballoon.pngDKR64-pipsyballoon.pngDKR64-timberballoon.pngDKR64-tiptupballoon.png

Balloons for each of the playable characters except Diddy, Conker and T.T.

Dino Isle

DKR64-dinoisle.png

A very small platform that would've been used somewhere in Dino Domain.

Wizpig Door

DKR64-keithpigdoor.png

An unused Wizpig door that would've likely been used in the Future Funland Wizpig track since the area where Wizpig's throne is has similarly shaped openings.

Pro AM 64 Balloon

DKR64-proam64balloon.png

A balloon that has three Pro AM 64 logos, the Nintendo logo, and the Rare logos. It likely would've been used in a logo sequence at the startup.

Red Balloon Sign

DKR64-signs.png

A sign with a red balloon on it.

Space Columns

DKR64-spacecolumn1.pngDKR64-spacecolumn2.pngDKR64-spacecolumn3.png

Three towers with the heads of Wizpig, Smokey and Tricky at the top of them that would've likely been used somewhere in Future Funland. Models for Bluey and Bubbler don't exist.

Wood Block

DKR64-woodblock.png

A block of wood.

Test Models

MSUSA64-lightcone.pngMSUSA64-lightcube.pngMSUSA64-lightcylinder.pngMSUSA64-lightsphere.png

Four test models.

Spaceship

DKR64-spaceship2.png

Horseshoe Gulch

DKR64-horseshoegulch1.pngDKR64-horseshoegulch2.pngDKR64-horseshoegulch3.png

Value: 10

An unfinished track that looks like an ordinary track, but isn't circular. The AI racers just drive around seemingly randomly. One of the arches is untextured. In the U V1.0, E V1.0, J versions of the game, Wizpig appear in the map on his rocket and flies in a set path. This map was likely used for testing the AI.

Sequence Area

Value: 24

The Adventure mode intro cutscene uses an earlier version of the main hub world which contains a few differences compared to the final version. Since this map can't be explored normally, these differences can't be seen.

Early Final
DKR EarlyMap1.png DKR FinalMap1.png
  • Behind the starting point, the log has a chunk cut out of it that was filled in for the final version.
Early Final
DKR EarlyMap2.png DKR FinalMap2.png
  • The area leading to Snowflake Mountain was originally a grassy area. The area can actually be seen in its completed form in an old German promo video.
Early Final
DKR EarlyMap3.png DKR FinalMap3.png
  • The tunnel leading to Dino Domain was originally much longer and had some vines growing in it.

DKR Early DinoDomain.png DKR Early SnowflakeMountain.png

DKR64-sequenceareawarp.png

This map contains an out of bounds warp which can be seen at the bottom of the image.

Front End

DKR64-frontend.png Mickeys-Speedway-USA-Frontend.png

A cube with a different color for each face. This map is actually loaded into memory during certain menus but is never visible in game. This map also exists in Mickey's Speedway USA and Jet Force Gemini.

Snow Mountain

DKR64-snowmountain1.pngDKR64-snowmountain2.pngDKR64-snowmountain3.png

A snowy version of the Dino Domain boss track. Other than being slightly shorter, this map is mostly the same.

Lagoon

DKR64-lagoon1.pngDKR64-lagoon2.pngDKR64-lagoon3.png

A lagoon map that seems to be an early version of Darkwater Beach. It has an anchor and some trees which use the same textures as the walls.

Volcano

DKR64-volcano1.pngDKR64-volcano2.pngDKR64-volcano3.png

A volcano themed track that seems to be an early version of Hot Top Volcano. Note: the balloon seen in the first screenshot isn't part of the level.

Jungle

DKR64-jungle1.pngDKR64-jungle2.pngDKR64-jungle3.pngDKR64-jungle4.pngDKR64-jungle5.png

A track that is very likely an early version of Jungle Falls. Several waterfalls, a tunnel, and a pyramid can be seen. The collision doesn't always match the track model, so you'll sometimes be floating in the air.

Extra Localizations

Looks German to me!
Japanese Japanese? Japanese Japanese Japanese.

Aside from the English and French options in the menu in the USA version, there are German and Japanese options, though the latter is not quite finished as it replaces much of the text in the game with placeholders.

Code 81084542 0001 replaces French with German in the menu; 81084542 0003 replaces with Japanese.

Unused Default Record Time

DKR64-defaultrecord.png

Levels in the game that don't contain any time trial records, like the hub world, will use a default record of 3 minutes with the best lap being 1 minute and with the name ABC.

Regional Differences

Spaceport Alpha Wall Textures

International Japan
DKR-tunnelU.png DKR-tunnelJ.png
  • The wall textures for the tunnel in Spaceport Alpha are different in the Japanese version of the game.

Resolution

US/JP EU
DKR64usres.png DKR64-eures.png
  • The North American and Japanese versions of the game render at 320x237 while the European version renders at 320x261. Only certain HUD elements take advantage of the higher resolution since the view is just stretched vertically.

Revisional Differences

Some revisional differences exist, most of them are to make Spaceport Alpha slightly easier.

  • After defeating Trickytops or Bluey for the first time, Taj tells you a gameplay tip. In 1.0, Taj speaks during the accompanying jingle, but in 1.1, his voice clip is delayed until afterwards.
  • The infamous "wrong warp" glitch from Hot Top Volcano works differently between versions. In 1.0, the game crashes once you go through the loading zone, but in 1.1, it warps you to the main hub world, loading the data from file 1. In the Japanese version of the game, the loading zone warps you to either the main hub world or Dragon Forest. This glitch can be heavily abused to beat the game in under an hour.
Version 1.0 Version 1.1
DKR64-sun1.png
DKR64-sun3.png
DKR64-sun2.png
DKR64-sun4.png
  • In Star City, a neon sign of sun was replaced with the N64 logo and some squares in the 1.1 version.
Version 1.0 Version 1.1
DKR64-kilogo1.png DKR64-kilogo2.png
  • The Killer Instinct logo in Star City was removed.
  • A space ship graphic in Star City doesn't animate in 1.1.
  • In the Japanese version, one of the walls in Spaceport Alpha has a hole in the top, which you can go through with a well timed loop-de-loop, allowing you to go out of bounds on the track. For some reason, this hole doesn't exist in any other version.
Version 1.0 Version 1.1
DKR1 Vent.png DKR2 Vent.png
  • The vent's graphics were changed to a somewhat glitchy blue texture.
Version 1.0 Version 1.1
DKR1 Wall.png DKR2 Wall.png
  • A wall was added near the vent to prevent players from going the wrong way.
Version 1.0 Version 1.1
DKR1 Hole.png DKR2 Hole.png
  • The hole directly behind the starting line was removed likely so that it wouldn't confuse players.

Oddities

Diddy's Tail

DKR64-diddyselect.png

In the player select screen, Diddy Kong has a tail, but it can not be seen due to the camera angle.

Taj's internal name

The object corresponding to Taj is known as Parkwarden internally.

Internal music track names

Several music tracks have internal names that suggest they were once meant for a different purpose:

  • The Jungle Falls music has the name boss_1a.
  • The snippet of music played when Taj tells you a secret after beating a world is named sndlap. (Second Lap?)
  • The fanfare played when obtaining a Wizpig Amulet Piece is named finlp_1b. (Final Lap?)

Unreachable Balloon

DKR64HiddenBalloon.png

Underneath the Dragon Forest boss track is an unreachable golden balloon.

Wrong Warp

DKR64-wrongwarp.png

For whatever reason, a normally inaccessible warp exists underneath the starting line in Hot Top Volcano (the green octagon in the screenshot). Where it warps you depends on the version you're playing.

Title Sequence

All areas from the title screen sequence are on the same map, albeit extremely spread out.

Boulder Canyon Height Limit

Boulder Canyon has a height limit for planes even though only hovercrafts can be selected in that track. It's possible that planes were going to be selectable as well in that track.

Spaceport Alpha Alcove

DKR64-alcove.png

Next to the starting line in Spaceport Alpha is an empty alcove that serves no real purpose. It's possible that Future Fun Land was going to have a battle mini game as well like the first four areas and that the key to unlock the door would've been placed here.
