This is a list of pre-release and unused content for ''[[Diddy Kong Racing]]''.
==Concept art==
The following are test renders for several elements conceived for the game during development, shared by the game's art director [[Kevin Bayliss]].

==Early builds==
The intro cutscene from Adventure Mode uses an earlier version of the hub. Players cannot normally see these parts of the map, but they are different from the final release.

==Unused data==
Some unused cheat and debug codes can be found. Placeholder codes are displayed as a string of numbers and cannot be activated in the cheats menu.
*High Speed Racing (code 1234567890): no visible effect
*Print Coord (code 8846325012): shows the player's coordinates on the upper-left corner of the screen.
*ROM Checksum (code DODGYROMMER): displays a checksum of the ROM when the player exits the cheat list.
*Free Balloon (code EOLAOBFENRLONE): gives the player one free balloon. The code is an anagram of "ONEFREEBALLOON". This code is usable in-game, but the code is not displayed in the credits sequence.
*EPC Lock Up Display (code EPC): if the game crashes, on the next start-up, the game will list a crash report, but the pages display only very briefly.
*Control TT (code 1058732594): Actually used as a cheat.
*Control Drumstick (code 8649305321): Actually used as a cheat.
*Mirrored Tracks (code 0986754321): Similar to Adventure 2, which mirrors the track.
The sound test, which can be accessed by inputting JUKEBOX in the code menu. Soundtrack 12 is unused, and its file name is sea_2b. The background music is originally intended to play on [[Crescent Island]]. The character select theme, which changes every time a player selects a character, also has a file for a sitar-sounding instrument, suggesting that [[Taj]] may have been considered to be playable.
===Unused tracks===
Horseshoe Gulch is found in the game's files and is partially usable. It displays the [[Fossil Canyon]] minimap. It includes data for [[Wizpig]] on his rocket, and as such may have been used for testing.<ref>[https://noclip.website/#DiddyKongRacing/16 noclip.website], Horseshoe Gulch</ref>

Other unused track files can be found as well, none of which have any programmed objects:
*A water-filled temple resembling [[Jungle Falls (Diddy Kong Racing)|Jungle Falls]] and [[Boulder Canyon]].<ref>[https://noclip.website/#DiddyKongRacing/model:10 noclip.website], Unnamed Temple Track (Model only)</ref>
*An ocean area resembling [[Darkwater Beach]].<ref>[https://noclip.website/#DiddyKongRacing/model:43 noclip.website], Unnamed Ocean Track (Model only)</ref>
*A lava cave resembling [[Hot Top Volcano]].<ref>[https://noclip.website/#DiddyKongRacing/model:44 noclip.website], Unnamed Volcano Track (Model only)</ref>
*A snowy version of [[Tricky's Course]], including its shortcut.<ref>[https://noclip.website/#DiddyKongRacing/model:model:45 noclip.website], Unnamed Snow Mountain Track (Model only)</ref>

===Unused graphics===
Some remnants of the game's beginnings can be found in the game's files, such as the Pro AM 64 logo, which was used when the game was initially a project called "''Pro Am 64''". Files for placeholder graphics for the character select screen can be found with placeholder text for [[Conker]], [[Timber]], and [[Banjo]], while images for [[Diddy Kong]] and [[T.T.]] are missing. [[Sherbet Island]]'s tracks have placeholder signs. There is a sign for Twilight City, which corresponds to a course in the [[Future Fun Land]] lobby, and its internal name (TWILIGHTCITY) corresponds to T.T.'s [[Star City]] sound effect. Several icons, used presumably for debug reasons, can be found. Models for balloons showing character heads exist.

Many of the below graphics are hidden textures that are used to mark special objects (like sound or visual effect sources, or object spawn points or directors). These were used in debugging during development, and were simply hidden in the retail version rather than fully removed.<ref>[https://noclip.website/#DiddyKongRacing/0;ShareData=AWqaJ9vUZM8:oHpUPJh!V,HQUQdguuUp^B4UNVp8V&S!y9ZmY3T6Mg-97Cy&+^ noclip.website]; option for "show developer objects" exists under "render hacks."</ref>
