Mickey's Speedway USA is a racing title by Rare in a style similar to Diddy Kong Racing, with the obvious exception that the drivers have been replaced with various Disney characters.


Debug Mode

MickeyDebugUSA.png

A simple debug mode can be enabled by entering the following button sequence on the title screen (directions refer to the d-pad):

Right, Up, B, B, Up, Left, B, Z

Alternatively, this GameShark code will also unlock the feature:

Version Gameshark code
USA 8007A1E3 0001
Japan 8007A2E3 0001
Europe 8007A4A3 0001

After the code is enabled, DEBUG TOGGLED will appear momentarily. Whatever "rub bulbz" is supposed to mean, the game will now display various details about player 1's position on the track: exact X, Y and Z coordinates, and the angle (A) their kart is facing.

(Source: Mezmorize)

Crash Debugger

The crash debug screen

If the game crashes without the debug mode enabled, it will display a basic crash debug screen with a version number.

If the game crashes with the debug mode enabled, it will display a more complex crash debugger which is almost identical to the one in Jet Force Gemini.

Unused Areas

All tracks can be seen in this video. Furthermore, all unused tracks use Speedway's "Malibu" music as a default. All of the unused areas and animations can be seen by using one of the below GameShark codes.

Version Gameshark code
USA 8007A14B 00??
Europe 8007A40B 00??
Japan 8007A24B 00??

Replace ?? with one of the below values, enable the code after the character selection screen and choose the practice track.

Speedway-USA-Final-White-House-03.png

Value: 07

There is an early version of the White House battle track. It is titled "maze" in the ROM. The collision is intact. There is an unused Token Dispenser on this track that shoots out a total of 20 "Oomph Tokens". The dispenser has no collision and can be driven through. The animation is intact and appears on the two unused battle tracks. This map contains 12 item boxes around the perimeter with 3 of them on each side. The final version only has 5 of them in the center.

Battle Tracks

The first two tracks are textureless and contain the unused Token Dispenser.

Battletest

Speeway-USA-battletest-01.png Speeway-USA-battletest-02.png Speeway-USA-battletest-03.png

Value: 09

The first battle track is named "battletest" in the ROM. The track features two towers at opposite ends, each with an entrance. The entrances go to an underground area, seen in the third screenshot. This map contains no item boxes.

Cascade

Speeway-USA-cascade-01.png Speeway-USA-cascade-02.png Speeway-USA-cascade-03.png

Value: 15

The second battle track is named "cascade" in the ROM. The main feature is that it has three height levels, cascading downwards. This map contains no item boxes.

Practice Track Battle

Value: 2C

There is also a carbon copy battle version of the Practice stage. It's identical to the original Practice stage, with the exception of any seagulls or chickens in their respective locations. Apart from having no AI programming, this map is mostly functional. It contains spawn points for the second, third, and fourth players as well as six item boxes with two of them in each area.

Test Map

Mickeys-Speedway-USA-Mushcan.png

Value: 06

A very empty test map exists. Its file name is "mushcan". There is a large empty space in the middle of the map. Some of the hole is actually transparent track.

xxFrontend

Mickeys-Speedway-USA-Frontend.png

Value: 00

A large empty cube. Each of its six faces are a different color. This "front-end" cube also appears in Diddy Kong Racing and Jet Force Gemini.

xxFrontend2

Value: 01

An identical copy of the above map.

Leftover Tracks from Other Rare Games

These maps are bare and do not contain any objects, unless specified.

Mizar Racer

Value: 02

The first leftover track is Mizar Race from Jet Force Gemini. All collision data is intact. The map may have been used for testing. Two object placeholders appear on the track: "Bomb Collect" and "Upside Down Collect".

Greenwood Village

Value: 04

The second leftover track is Greenwood Village from Diddy Kong Racing, specifically the version from Jet Force Gemini which removed the well shortcut near the start. Collision is intact and this map may have been also used for testing. Unlike the Mizar Race track, this one can be completed and even has a path for the AI to follow.

Unused Multiplayer Mode: Capture the Flag

The unused battle tracks have proven that there is an unused multiplayer mode in which players must collect Oomph Tokens and bring them back to their personal hub. This mode appears in the "maze", "cascade", and "battletest" maps. In the "cascade" map, all four player hubs are next to each other. Once the player drives over their hub, the tokens disappear and more tokens are shot out of the Token Dispenser. "Maze" allows for a total of 20 tokens on the map at one time, whereas "cascade" and "battletest" limit this to 8 tokens.

Unused Textures

Speedway-USA-Early-Logo.png

The most noticeable difference is that Speedway is blue instead of yellow. This is identical to the logo shown in the E3 2000 demo. The USA lettering is also missing white stars on the blue border.

Early Track Previews

Speedway-USA-Old-Track-Great-Wall.png Speedway-USA-Old-Track-Hawaii.png Speedway-USA-Old-Track-Niagara-Falls.png Speedway-USA-Old-Track-Washington-DC.png

There are four preview images that suggest the game was originally going to be a world tour instead of just the United States. The tracks appear to be The Great Wall of China, Hawaii, Niagara Falls, and Washington D.C. respectively.


Speedway-USA-Washington-DC-Hawaii-Final.png

Hawaii and Washington D.C. are tracks in the final game, but their preview images are quite different.


Early Trophies

Speedway-USA-1st-Flag.png Speedway-USA-2nd-Flag.png Speedway-USA-3rd-Flag.png


Speedway-USA-1st-Plate.png Speedway-USA-2nd-Plate.png Speedway-USA-3rd-Plate.png

The flag and plate textures for each trophy. 2nd and 3rd place are somewhat obscured when viewed in-game due to the forced camera angle.

Options Menu

Speedway-USA-Options-Screen.png

When entering the options menu, a device quickly opens to display the settings. There are two outer textures that can barely be seen every time.


Speedway-USA-Options-Tab-1.png Speedway-USA-Options-Tab-2.png

Underneath the Gone to Lunch note is an embossed Von, similar to the one on Von Drake's PC.


Speedway-USA-Art-Of-Walt-Disney.png

This is the cover of the book underneath the options device. The cover is mostly obscured in-game, but this texture reveals that it's the 1995 revision of The Art of Walt Disney.

Jet Force Gemini Leftovers

Speedway-USA-JFG-Skybox.png

The infamous skybox seen in all of the unused tracks.


Speedway-USA-Mizar-Tokens.png

Textures for Mizar Tokens are in the game, despite not appearing on the actual Mizar track.

Unused Animations

Mickey's Head

Value 03

Speedway-USA-Early-TV.png

Internally known as "Mickeys Head" is an animated version of the image used on the TV in the main menu. It was likely meant to be a title screen or menu.

Mickey's Head Short Tune

Value 13

A seemingly identical copy of the above animation.

Detailed Trophies

Value 05

Speeway-USA-Trophies.png

These trophies are never seen in the game. The gold trophy continually rotates on a horizontal axis and the silver & bronze trophies stay still. There are sparkle effects on the trophies. The flags and plates can be seen more clearly in the textures section above. Its internal name, "Level Select", indicates that it may have been a difficulty select at one point.

Value 0D

Speeway-USA-Castle-Logo.pngMickeyUSA64-castle.png

Internally known as "Castle", this is the well known Disney Castle Logo rendered in 3D, which was meant for the beginning credits. The resolution changes depending on how it's accessed. If brute forced, it'll be rendered at 446 x 331 pixels. If accessed using the below codes, it'll render at 320 x 237. If the player brute-forces their way into this scene, it doesn't render the fireworks effect or the Disney logo. To see this scene as intended, use the following codes and press L and R simultaneously.

Disney Castle Awards Ceremony

Value 0E

Speeway-USA-Castle-Awards-01.png

This castle appears to resemble Le Château de la Belle au Bois Dormant, the castle present at Disneyland Paris. There's a short animation and song here. Once the song is done, a cartoon *bang* sounds. There appears to be a transparent gold award falling from the top of the screen. The animation is internally known as "sb_Castle".


(Source: SubDrag & Coolboyman)

Unused Music

Unused Ceremony Song

A short song that plays during the Disney Castle Awards Ceremony. It can still be listened to in the sound test as tune number 7.


Malibu (Early Version)

An early version of the song for Malibu. It can still be listened to in the sound test as tune number 8.

Unused Dialog

Broken Records in Time Trial

Each character (except Goofy, Donald, and Dewey) has dialog for breaking a course record. The final game uses one of three "New record!" lines from the nephews.

Mickey's Record

Pete's Record 2
Huey's Record
Louie's Record
Ludwig's Record

Oh, this is good!
Oh, use that!
There you go!

Other

Three laps to go!
Four laps to go!

A couple of unused menu sounds that were used in the E3 2000 demo version.

Mickey Racing

Unused Models

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. This is also used in Diddy Kong Racing and Jet Force Gemini.

DKR64-animation.png

A multicolored arrow.

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

Test models.

MSUSA64-charselframe.png

An unused character select frame. This was used in the E3 2000 version of the game.

MSUSA64-redtoken.pngMSUSA64-greentoken.pngMSUSA64-bluetoken.pngMSUSA64-missile.pngMSUSA64-door.png

Leftover models from Jet Force Gemini.

Unused Starting Points

The New Orleans Track contains six starting points at the starting line. However, since the track never appears in any of the grand prix cups, only the first four are ever used.

Regional Differences

Title Screen

Europe/North America Japan
Mickey's Speedway USA-title.png Speedway-USA-Title-J.png

The Japanese title screen actually shows Mickey. The Japanese version uses a different font style for English lettering.


Indianapolis Tire

Europe/North America Japan
Speedway-USA-EU-NA-Tire-Texture.png Speedway-USA-JP-Tire-Texture.png

The text on the giant tire in the Indianapolis track was changed from Speedway to Speedy. This was most likely because the Japanese game title doesn't have the word speedway in it.


Speedway-USA-Indianapolis-Time-Trial.png

The time trial preview image was also changed accordingly.


Options Menu Typo

Europe North America
Speedway-USA-Triple-E.png Speedway-USA-Triple-U.png

Triple is misspelled in the European release. This is peculiar, because the European version was released after North America.


Unlocking Huey

In the North American/European release, Huey can only be unlocked when booting up the game with the GBC release in a transfer pak. Since the GBC version was never released in Japan, Huey is unlocked when the player gets their first time trial Ghost Token.
