Debug Menu

This game contains a debug menu; to enable it, use one of these GameShark codes and press L+Z at the title screen.

Version	Gameshark code	Version	Gameshark code	Version	Gameshark code
USA	D10F6914 2020 8018EDEF 0002	Japan V1.0	D10F73C4 2020 8018C80F 0002	Japan V1.1	D10F61B4 2020 8018B5BF 0002

In the debug build of the game that was leaked as part of the July gigaleak, the debug menu is enabled by default and can be activated by pressing R on the title screen.

• DEBUG_MODE activates key combinations during play:
  • L+R+A+B: Reset game.
  • R+B: Toggle CPU meter.
  • D-Pad Right: Advance player 1 and everyone behind them to final lap.
  • D-Pad Down: Advance everyone to final lap.
  • D-Pad Up: Advance player 1 and one other to final lap.
  • Z or C-Down can be pressed during the race start sequence to start early. This will glitch the game if done too soon.
• MAP_NUMBER selects the track. Available are the 16 single-player tracks plus the four tracks from battle mode.

Level Select	Course
0 M CIRCUIT	Mario Raceway
1 MOUNTAIN	Choco Mountain
2 CASTLE	Bowser's Castle
3 GHOST	Banshee Boardwalk
4 MAZE	Yoshi Valley
5 SNOW	Frappe Snowland
6 BEACH	Koopa Troopa Beach

15 BLOCK	Block Fort
16 SKYSCRAPER	Skyscraper
17 DECK	Double Deck
18 JUNGLE	D.K.'s Jungle Parkway
19 DOUGHNUT	Big Donut

• SCREEN_MODE selects the screen mode, and thus the players that participate. Available values are 1 player, 2 player up/down, 2 player left/right, 3 players and 4 players. The two player left-right view is never used in the final game, and is somewhat glitchy.
• PLAYER selects the first player. If you have more than one player, the game assumes Luigi for player 2, Yoshi for player 3 and Toad for player 4.
• SOUND MODE simply selects the sound mode (mono, headphones, stereo).
• PUSH B TO GET ALL GOLDCUP is fairly self-descriptive. This option only appears when the cursor is moved all the way to the bottom.

Note that if you try to start a one-player game on a battle map, the game will automatically add a second player.

XXX Sound Mode

GameShark code switches the sound mode to "XXX" on the debug menu and blank in the Options menu. Its purpose is not known.

CPU and Graphic Display

When Debug Mode is enabled, the following GameShark codes can be used:

• Debug Mode Enabled.

Europe V1.0	800DC5A5 0001	Europe V1.1	800DC535 0001

• Shows bars at the bottom measuring CPU usage of the video (red), audio (yellow) and game logic (orange) threads.

Europe V1.0	800DC6F1 0001	Europe V1.1	800DC683 0001

While the CPU meter is enabled, pressing L+R toggles a flag at 800DC664, but this flag doesn't seem to be accessed anywhere else. (This is done at 80004098.)

Frame-by-Frame advance

The following code activates a frame-by-frame advance mode if Debug Mode is enabled:

Version	Gameshark code
USA	81001760 3C03 81001762 800E 81001794 3C0B 81001796 800E 810017C4 240C 810017C6 0000

When the game is paused, player 1 can hold A and B and press L to advance a frame. This unfortunately conflicts with using A to unpause the game; you must hold A before pausing. Alternatively, adding the code 81001784 2400 makes it require only holding B and pressing L while paused.

Crash Debug Screen

If the game crashes, it will draw a small white square with red border near the upper left corner of the screen. At that point, entering the code L, Up, Left, Down, Right, R, L, B, A will display some information about the cause of the crash.

The first line displays three numbers - first is unknown (usually 5, probably thread ID), second is the address of the faulty instruction, third is the exception code (as defined in the R4300i manual). The second line displays the $RA register. The third line is the opcode of the faulty instruction.

The GameShark code 810DC6FE FFFF will shorten this code to simply "press L".

This display cannot be seen on most emulators, as most plugins don't seem to continue redrawing the screen after the game crashes.

Unused Code

To do: Supposedly there's some coding that allows A.I. racers to drift.

Track Scaling Function

Next to the mirror mode flag in memory (address 800DC608 in USA version) is a floating-point value that appears to always be set to 1.0. When a track is loaded, its height is scaled by this amount. (All polygon vertices are multiplied by this value.) Use one of the below GameShark codes to activate this feature. (default value 3F80)

Version	Gameshark code	Version	Gameshark code	Version	Gameshark code
USA	810DC608 ????	Japan V1.0	810DCED8 ????	Japan V1.1	810DBE18 ????
Europe V1.0	810DC698 ????	Europe V1.1	810DC628 ????

This value only affects track polygons, and hit detection is not altered to compensate for the steeper hills and/or shorter vertical walls, so changing it often produces unplayable tracks and strange effects such as floating trees, low areas being considered underwater/out of bounds, and walls that are no longer solid.

No similar scaling functions exist for the X and Z axes. This may have been intended as a debugging function to test slopes, or a bonus mode that would scale tracks to various sizes.

Vertical Splitscreen

This unused vertical splitscreen display for 2-player mode is only accessible via the Debug Menu or by using the following GameShark code below that forces the horizontal splitscreen mode to the vertical splitscreen mode when selecting a 2-player game:

Version	Gameshark code	Version	Gameshark code	Version	Gameshark code
USA	D00DC533 0001 800DC533 0002	Japan 1.0	D00DCE03 0001 800DCE03 0002	Japan 1.1	D00DBD43 0001 800DBD43 0002
Europe 1.0	D00DC5C3 0001 800DC5C3 0002	Europe 1.1	D00DC553 0001 800DC553 0002	iQue	D00D8ED3 0001 800D8ED3 0002

It's pretty clear why this isn't accessible normally: it's unfinished. The lap counter still displays in Battle Mode, the map goes over the second player's lap counter, and the V's and E's only appear when you're close to the camera.

This feature can be seen in some very early footage of the game from when it was known as Super Mario Kart R.

Lightning in Battle Mode

When used in Battle Mode, the Lightning Bolt makes all other players lose one balloon; however, it isn't normally possible to obtain this item, likely because it would have made battles horribly unbalanced. Code that specifically handles the Lightning Bolt's effects in Battle Mode can be found around 8008E0FC in RAM.

Bomb Warning

An unused multiplayer feature that warns players when they approach the moving bombs on the track. This can be seen in an early screenshot but was disabled in the final game. It can be re-enabled by using the GameShark codes:

Version	Gameshark code
USA	D10F6914 0002 800DC53B 0001

Start up a 3 or 4 player versus race then once in game, press C-Left once and drive near a bomb and then press C-Right until you see the bomb icon.

Feather Jump State

The player-state code contains a flag indicating a feather jump state is active. By setting the state at 0x0F699E (NTSC-U) to 0x10 it triggers an immediate feather jump on the player. The feather item from Super Mario Kart wasn't included in the final game, though it can be seen in certain prerelease material.

(Source: tasvideos.org)

Code from the 2020 Nintendo leaks labels this flag as USE_WING, which shows that this state would have been activated via use of an item, in this case the scrapped feather.

Storm Hit State

Another player-state code has a flag used to trigger a large spinning jump, which can be activated by setting the state at 0x0F699D (NTSC-U) to 0x02. When active, the character gets flung into the air in a similar fashion to the feather jump, but with much more height and less forward momentum. The character plays a negative voice line (the same as for a banana spin out) and upon landing on ground, it removes all momentum. By observation and labelling, this was meant to be a negative player-state.

Code from the 2020 Nintendo leaks labels this flag as HIT_STORM, which suggests that this state would have been used for colliding with the scrapped tornado and typhoon hazards presumably found in Kalimari Desert and other courses respectively, for which commented out code has been found.

CPU Shell Code

The game contains six tables that determine the item probabilities when hitting an item box. The first two tables are both for GP mode and determine item probabilities for a human player and a CPU player, respectively. According to the latter, CPU players have a certain chance to get Green Shells, both the single and the triple variety, but the CPU never uses shells at all, so this isn't actually ever seen in gameplay.

Unused Graphics

Menu Graphics

Among the menu graphics are two unused options, untranslated from Japanese:

Graphic	Translation
	Without Item
	With Item

Bomb Warning Icon

The bomb warning icon that shows when you're close to the moving bombs.

Early Traffic Light

An early version of the traffic light.

Early Item Boxes

The textures for the early item boxes. It's a leftover from Super Mario Kart R.

Player HUD

4 Player HUDs for the multiplayer modes.

(Source: Origami64)

Monty Mole

While these two sprites are technically used while Monty is preparing to spring out of its hole, the player never sees the lower body while Monty is standing still.

(Source: Ragey)

Position Numbers

Even though the game has 8 racers, there are unused 0th and 9th position icons for the lap progression HUD.

"GO" Sign

Texture	In-game

The bottom part of this texture cannot be seen, as the sign is too small to have the full texture. The full sign can be seen in some prerelease material.

Stylized Leaf

Although present in the game files, this leaf texture isn't used. It was probably meant to fall out of the striped trees, based on its appearance.

The code below replaces the realistic leaves with this unused one, when hitting a tree.

Version	Gameshark code
USA	810516AA 91D8 810516AE 0010

Shy Boo Animation

Together with the 360 degree render sprites comes this animation of a Boo, hiding its face.

Boos can bee seen floating around in the course "Banshee Boardwalk" yet this specific animation is never used.

Misplaced Item Boxes

Hidden underneath the Big Donut arena are two misplaced item boxes. These item boxes can be seen by getting the camera behind the green bars and waiting, eventually the two item boxes will float up into view. The stored Z-value of these two boxes is about 100 units less than all the other 22 boxes, causing them to appear below the course.

Since the red, blue and yellow sections of the map each contain six Item Boxes whereas the green section contains four, it's clear that these two Item Boxes were intended to appear in the map.

A Gameshark code to restore the two boxes to the course surface:

Unused Early Banshee Boardwalk Ceiling

The course "Banshee Boardwalk" contains an unused piece of geometry, which only can be seen in the credits scene by manipulating the ingame camera.

It can not be seen in a regular race, since the game never loads it in via the culling system, however the credits sequence is set up to render every part of the level regardless of its culling state.

The layout and an unsealed part of the ceiling suggests that is has been used in an earlier rendition of this course.

Hidden Music Loop

The "Winning Results" track was likely intended to alternate between two ~100 second sections of music, each composed of a 50-second segment repeated twice. Due to a binary counter bug, the first segment repeats, incidentally, 64 times (for 54 minutes and 39 seconds!) before the second segment ever has a chance to play—at which point it repeats twice and correctly returns to the first segment.

Debugging Text

Most of this text probably would have been spat out to a debug console on development systems, but goes unused in the final game.

Version Differences

To do: Check for any differences between the European 1.0 and 1.1 versions.

Audio Differences LOTS of audio was changed from the Japanese version.

Billboards

To do: It'd help if someone could rip the graphics that aren't here yet.

The billboards in the Japanese version are all clever parodies of real-life companies. They were (mostly) changed during localization because this would have gotten Nintendo of America in hot water.

The iQue version's billboards are based on the international designs, with the exception of the "Shot!" billboard, which was replaced with the iQue logo.

Japan	International

Marioro (a pun on Marlboro) was changed to Mario Star.

Japan	International

Luigip (a pun on Agip) was changed to Luigi's, itself appearing to be a parody of the now-defunct Bradlees chain of discount stores.

Japan	International

Yoshi1 (a pun on Mobil1) was changed to Yoshi, with a pawprint similar to the one added to English versions of Super Mario World.

Japan	International

The Koopa Air sign is colored yellow and blue in the Japanese version (a pun on Goodyear). It's white and violet in international versions.

Japan	International

The Nintendo logo billboard is blue in the Japanese version and red internationally, reflecting its most common depictions in each region.

Japan	International

The orange 64 ball in Luigi's Raceway (a parody of the 76 gas station) was changed to blue and the 64 was given a different design.

Since none of the track preview icons were updated, the orange ball can however still be seen on the track preview even in international versions. In Mario Kart 7's version of the track, the ball was changed to yellow, but is otherwise based on its Japanese design.

The Luigip and Yoshi1 billboards can still be seen in the icon for Mario Raceway and the Yoshi1 billboard in Royal Raceway's icon.

Luigi's Raceway

The Japanese version has collision on the grass above the tunnel on Luigi's Raceway, which can be reached by bouncing off another racer and flying over the wall. The collision was removed in international versions so trying the same there just leads to you falling into the tunnel (or out of bounds, if unlucky).

Moo Moo Farm

The course "Moo Moo Farm" is called "Moh Moh Farm" in Japan. This is because mooing in Japanese is pronounced with a long "O" sound, which sounds like "moh moh".

Japan	North America

(Source: The Mushroom Kingdom)

On NTSC-J 1.0, moles can be hit while using a boo item, causing them to be launched away. All other versions have no mole collision while in this state.

(Source: abney317)

Toad's Turnpike

On NTSC-J 1.0, when getting stuck out of bounds, Lakitu places you back based on where you last touched the ground. In all other versions, Lakitu places you back on the track based on where you got stuck out of bounds.

Trophy Ceremony

The trophy ceremony in the Japanese version displays the text "You are in (position)". The international versions change this to "You placed (position)". The punctuation was also removed, and the position itself is made purple.

Japan	International

(Source: The Mushroom Kingdom)

Course Ghost

The course ghost text is different depending on the region.

Japan	International

Time Trial Replay Bug

In time trials on NTSC-J 1.0 when the race ends, if the autopilot driver hits something that would normally make it so you can't replay or save your ghost, then it disables the replay option.

(Source: abney317)

In the Japanese version, completing the Special Cup on Extra Mode will display a Japanese-language version of the credits. This was removed from the English version for obvious reasons.

Additionally, the Japanese version has six voice actors, while the English version only has three. Charles Martinet (the voice of Mario) is the only one to be credited in both versions. Additionally, his name is misspelled as "Charles Martinee" in the Japanese version. Thomas Spindler (the voice of Wario) and John Hulaton (the announcer) also have their names misspelled.

Wii Virtual Console Differences

Although the Wii Virtual Console releases use the exact same ROMs as the cartridges, some minor visual differences exist due to emulation errors and in-memory patches. These changes are not present in the Wii U Virtual Console release.

Nintendo 64	Wii Virtual Console

• The color scheme for the train in Kalimari Desert was changed.

Nintendo 64	Wii Virtual Console

• The waterfall on Koopa Troopa Beach is a brighter blue instead of grey.
• The characters/numbers of the timer are spaced out by 1 pixel.
• The flash from using lightning was toned down to avoid risk of seizures.

To do: Figure out what these changes in the Wii U version do and document them.

iQue Player Differences

The game was released in China for the iQue Player in December 2003. Like most games for the system, it is based on the international version.

• The billboards have been translated.
• Most references to the Nintendo 64 were replaced with ones to the iQue Player. The only exception being the train in Kalamari Desert which still has the number 64 on the front.
• The Controller Pak manager is inaccessible since the iQue Player handles Controller Paks differently to the Nintendo 64, as each game that requires a Controller Pak has its own .pak file on the iQue Player's NAND.
• An audio glitch occurs when entering a race, going back to the main menu, going to the data screen, and then backing out to the main menu again that causes the menu music to play in a slow and low pitched tone.
• When improving your best lap in time trials, instead of the usual flashing lap time, the time is not visible during the race at all.
