This game/console's online features are no longer supported. While this game/console's online features were once accessible, they are (as of April 8, 2024) no longer officially supported and online-exclusive features may be documented as now-unseen content.

Mario Kart 7 is essentially the same thing as Mario Kart Wii but more rocked up and in 3D. Oh, and you can paraglide, drive underwater, use seven items at once, race seven ghosts at once, and the character roster is different...but other than that, pretty much the same.

Also, the Honey Queen is here, but did we mention that Waluigi isn't present? (This wouldn't be the last time that he got snubbed...)

To do: Unused Staff Ghost Mii data (in /replay), in offsets 0x30-0x8F (length = 0x60) in each *.dat file. The last 4 bytes of said Mii data seem to be some kind of checksum. See the Notes subpage. (Unused?) Grand Prix A, B and C rank graphics in UI/trophy.szs, named tro_grade_X.bclim (with X being either a, b or c) Document the early version of KartConstructInfo.bin found in /Kart (the final version is found inside /Common.szs/Kart). The early version mentions the unused kart std_lod_oneTest. Add information about the USA and EUR kiosk demo of the game, and some of the kiosk files found in retail and viceversa. Spanish and French text differences between the US and European versions. This page mentions unused objects Just like in MKWii, this game also features the cameras and routes that were used for the creation of the little preview videos seen in the course selection screen. These go unused, given how these previews are stored as video files.

Bugs

Unused Graphics Various textures and models from before they were tuned up.

English Translation Differences Thankfully not as complicated as the previous game.

Unused Sounds/Music

Sequenced (MIDI) version of Time Trials start fanfare

This is a sequenced (MIDI) version of the fanfare that plays when starting a Time Trial. Sequenced starting fanfares are used in Download Play, for the racer who isn't playing with a cartridge. However, Time Trials is not available when playing from Download Play, so this goes unused.

Its filename is SEQ_FANFARE_START_TA.bcseq, and it's located from 0x7683C0 to 0x7687DF in the file /Sound/ctr_dash.bcsar in the RomFS.

Enable the code below and start a Time Trial to hear it:

Unused Battle Mode Frontrunning Beats

The songs used in the arenas in Battle mode have frontrunning beats that are never used, however only the nitro track ones were synced. The nitro tracks' bpm is 169 for the normal version, and the final minute's bpm is 185. All the retro tracks use a default 120 bpm for both the normal and final minute versions. Mockup versions were made only for the nitro tracks, since the retro ones weren't synced.

Wuhu Town (Final Minute)

(Mockups: TZ Gaming)

Rainbow Road

All of the sound effects Rainbow Road uses were ripped directly from Mario Kart Wii, even an early sound from the game. However, all of the Chain Chomp sounds from that game were also included, some of which don't get used.

Colliding with the Chain Chomp in Mario Kart Wii. Uses a different sound instead.

The launching sounds for the Chain Chomps in Mario Kart Wii. These played before the battle started at Chain Chomp Roulette. In this game, nothing plays. According to GRP_CN_RAINBOW_ROAD.bcgrp and ctr_dash.bcsar however, these sounds are set to play. They just don't play for some reason. It's unknown as of right now if these sounds can trigger.

DS Waluigi Pinball

Rainbow Road Sound

Strangely, in Waluigi Pinball's Sound File (GRP_CR_DS_WALUIGI_PINBALL.bcgrp), there is a copy of a sound used in Rainbow Road and SNES Rainbow Road.

Unused Countdown Sound

There is an unused sound for a countdown starting from 10 seconds (like in Mario Kart Wii) named SE_RC_BTL_CD_10_9_8.bcwav. The sound is identical to the one from Mario Kart Wii, so it was most likely carried over from that game.

Dummy Sounds

In the sound file (/Sound/ctr_dash.bcsar), there are 2 dummy Shy Guy sounds at the very end. All the used character sounds are in the middle of the BCSAR file. It isn't currently known what their names are.

Gctr_MarioCircuit_Divide (Early Mario Circuit Track)

Download Gctr_MarioCircuit_Divide.szs (Restoration) File: MK7 Gctr MarioCircuit Divide Restoration.zip (1.30 MB) (info)

This is the only unused track in the game. It is essentially an early version of Mario Circuit, with slightly different geometry, collision and parameters. There are no references to this course in the game's code.

Course archive (.szs)

Since the course archive lacks many important files, and the course information (kmp) file is in an early format, the track crashes when trying to load it.

The following files can be found in the course archive:

File Name	Description
Gctr_MarioCircuit_Divide.bclgt	Light information file, similar to the final version found in the Mario Circuit course archive.
Gctr_MarioCircuit.bclgt (*)	Another light information file, differs from the previous one and the final version.
Gctr_MarioCircuit_Divide_ch0.bclgt	Character light information file, uses different internal names than the ones found in used courses.
Gctr_MarioCircuit_Divide.div	Model division file, seems to match the main course model appropriately.
Gctr_MarioCircuit_Divide.bcmdl	Main course model file, more info below.
Gctr_MarioCircuit_Divide.kcl	Main collision file, matches the main course model appropriately, more info below.
Gctr_MarioCircuit.kcl (*)	Another collision file, doesn't match the main course model nor the final Mario Circuit course model, more info below.
Gctr_MarioCircuit_Divide.kmp	Course info file, more info below.
Gctr_MarioCircuit_Divide_map.bcmdl (**)	3D model of the course minimap.

(*) This file is a duplicate file and should not belong to this course archive.
(**) This file is unique and cannot be found in any other course archive.

The following files are missing from the course archive:

File Name	Description
UIMapPos.bin	Determines the position offsets for the bottom screen minimaps.
Gctr_MarioCircuit_Divide_map.bclim	Bottom screen global minimap (small)
Gctr_MarioCircuit_Divide_map2.bclim	Bottom screen global minimap (full)
Course Object Models	3D models for the objects defined in the kmp (Skybox variant 1, Goomba, Red Mushroom, Tree Variant 1 and pipe models).

Course Model (.bcmdl)

The .bcmdl course models are quite similar between the early and final versions, however a few textures are different. The spotlight texture was stretched to double the width and the castle wall texture and shading was slightly modified (matching prerelease footage). The four small trick ramps are missing, so the shadow map lacked shadows for these.

Early	Final

In addition, the early version in general is a bit bigger, there are no trick ramps, and the texture animation for the water doesn't loop, so it will only play once before stopping completely.

Collision (kcl)

Strangely, there are two collisions files Gctr_MarioCircuit.kcl and Gctr_MarioCircuit_Divide.kcl inside the .szs, second concording with the model.

They are almost identical to each other. The only difference seems to be that, in Gctr_MarioCircuit.kcl, when players drive into the flowers located before the entrance of the castle, the tires won't emit a flower graphical effect.

Both collision models don't have a water barrier. This is because the water barrier is actually added as an object in the early version, rather than being part of the collision model. Said object is named internally as WaterFix (ID 0x132).

The glider pad uses the same collision type that is used in the blue glider mushroom from Wii Mushroom Gorge. Mario Circuit originally had a bouncy mushroom instead of a glider pad when exiting the castle.

Interestingly, both collision models show that, originally, the dirt path located after the exit of the castle used to be connected with the castle walls.

Course info (kmp)

The early kmp is partially empty, only global objects, routes and areas exist. Checkpoints, cpu/item routes, respawn points and some other necessary sections to make the course load are missing.

• The course doesn't have any itemboxes or coins.
• There are three large Goombas rather than two normal-sized ones.
• The air flowing from the pipes near the gliding section is missing.
• The course uses Toad Circuit trees in the early version, rather than pink Sakura trees.
• There are no hills in the background of the track when you start the race.
• The course has replay/result cameras that go unseen, as there are no checkpoints defined, so players won't be able to complete the race to see them. Most of them are very different to the cameras in the final version of the course. The one located at the end of the pipe before the finish line seems to be a leftover from the beginning of the game's footage seen at E3 2010. Curiously, there are 3 extra cameras located out of bounds to the east of the finish line. They cannot be activated normally, as the triggers (AREAs) that are used to trigger these are also located out of bounds as well.

Touch Screen Map

The bottom screen map is stored in a different model (.bcmdl) in the same way as Mario Kart Wii did, instead of an image file (bclim). It even has the two bones that are used to position the map, named exactly how all minimap models from Mario Kart Wii are (posLD and posRU).

Unused Car Route in Wii Coconut Mall

There's an unused route in Wii Coconut Mall that suggests that the third car (which appeared in the Wii version) also appeared here at some point in development. Here, they extended its path so that it goes from wall to wall, rather than from one of the walls to the boost panel like in the Wii version.

Unused Code

Unused Super Thwomp Behavior

Super Thwomps, the type of Thwomps that appear in SNES Rainbow Road, have unused code that removes the Star item effect from players when they are stomped.

This is impossible to achieve in the normal game, since the Star item makes the player completely invincible to those enemies. In the adjacent video, a cheat code was used to make players vulnerable to Super Thwomps while on a Star, in order to show the unused behavior.

This behavior is only found in Super Thwomps, and not regular Thwomps. The function that manages this behavior is named Kart::VehicleReact::reactStarEnd(), and can be found at RAM address 0x002DF154 (US v1.1 prepatched, aka US Rev1). Said function is only ever called from Field::ObjectStarDossun::doReaction_againstKart + 0x148, at RAM address 0x0038B790 (US v1.1 prepatched, aka US Rev1).

Unused 99 coins limit in Coin Runners

The game stores a maximum coin limit variable, which is usually 10. However, for Coin Runners exclusively, said limit is set to 99. This is all done in function RaceSys::KartInfo::init (set by the instruction at 0x00468FE8 in RAM, USA Rev1).

Despite this, it's not possible to get more than 10 coins in Coin Runners, much like with every other mode. This is due to some code in function Object::CoinManager::addCoin that prevents the player from adding more than 10 coins.

If we remove those checks, the player will be able to score up to 99 coins in Coin Runners as originally intended by the developers, which we can do by using the following Gateway code:

	USA Rev1
Gateway Code	00416028 EA000002 00416044 E320F000

Unused Objects

Objflow

Objflow contains all the info on the game's objects, which acts as a database file to load the objects themselves and give them unique IDs. However, this file also has some unused object entries. Some of which are duplicate entires of current objects (possibly test or earlier variants of them), and some objects that don't exist in any track at all. No models of those exist. Most of these also don't have any references in the game's code.

• jugem - A Lakitu object. This could be related to a planned addition to Winning Run. Uses ID 0x09.
• RrStarRing - Unused Star Ring. Uses ID 0x11. The used one is 0x17F.
• MovingRoad - Possibly a test object for a moving road. Uses ID 0x12. Unlike the other objects, this one is actually referenced still in the game's code.
• MovingRoad2 - Another moving road test. Uses ID 0x15. Unlike the other objects, this one is actually referenced still in the game's code.
• MovingRoad1 - Same as above. Uses ID 0x16. Unlike the other objects, this one is actually referenced still in the game's code.
• CruiseShip - A removed cruise ship object. This was probably a background object. Uses ID 0x73.
• StPotSnake - Early version of the Snake Pot. It's possible they went for a different approach with the snake pots earlier in development. Uses ID 0x78.
• killer - Bullet Bill object. Technically this is used, but it's linked with DsCannon, so this object itself doesn't get used. Uses ID 0xD2.
• CmnStartGrid - Unused Start Grid. Uses ID 0x148.
• DsSkyCastle - Removed Sky Castle object. Possibly meant to be a background object for DS Airship Fortress. Uses ID 0x14A.
• WiiParasol - Removed Parasol object. Possibly meant to be a decoration for Wii Coconut Mall. Uses ID 0x15A.
• CmnTree1 - Duplicate Tree Variant 1. Uses ID 0x169. The used one is 0x130.
• CmnTree2 - Duplicate Tree Variant 2. Uses ID 0x16A. The used one is 0x133.
• CmnTree3 - Duplicate Tree Variant 3. Uses ID 0x16B. The used one is 0x157.
• CmnTree4 - Duplicate Tree Variant 4. Uses ID 0x16C. The used one is 0x149.
• CmnTree5 - Duplicate Tree Variant 5. Uses ID 0x16D. The used one is 0x15F.
• WiTree1 - Duplicate Wii Tree Variant 1. Uses ID 0x16E. The used one is 0x134.
• WiTree2 - Duplicate Wii Tree Variant 2. Uses ID 0x16F. The used one is 0x135.
• WiTree3 - Duplicate Wii Tree Variant 3. Uses ID 0x170. The used one is 0x136.
• DsDeadTree - Duplicate Dead Tree. Uses ID 0x171. The used one is 0x14D.
• DsSpookytree - Duplicate Spooky Tree. Uses ID 0x172. The used one is 0x156.
• GcTree1 - Duplicate GC Tree. Uses ID 0x173. The used one is 0x161.
• MrBush - Removed Bush object for Cheep Cheep Lagoon. This was probably the seaweed, which is part of the track model instead. Uses ID 0x179.
• IsAnemone - Removed Anemone object for Rosalina's Ice World. This was most likely the Anemone already present on the track in the underwater section, which is part of the track model, however they aren't animated. It's possible at some point they were going to be animated. Uses ID 0x185.
• RrMovingRoad - Unused Moving Road for Rainbow Road. Uses ID 0x186.
• UgTreeS - Removed Small Tree for Piranha Plant Slide. Most likely removed since the trees are part of the track model rather than objects. Uses ID 0x194.
• UgTreeL - Same as above, except Large Tree. Uses ID 0x195.
• SfcMovingRoad - 4 unused versions of the SNES Rainbow Road Moving Roads. Uses IDs 0x19B-0x19E.

Unused Battle Mode Item Functions

The Blue Shell, Lightning, and Bullet Bill can't be obtained under normal circumstances. These items will have unusual effects when hacked in.

Blue Shell

Acts like a Green Shell but it goes on forever. The game crashes if it goes out of bounds.

Lightning

Shocks the players but it doesn't always give out a point per player. The players do not shrink, and they keep any items they had.

Bullet Bill

Follows a route similar to the CPUs, and like the Blue Shell, the effect lasts forever. It performs tricks automatically. After a while it will get stuck in a loop.

Unused "Race Number" Strings

Inside the message file at UI\common-XX.szs\Common.msbt, there are the messages for indicating the race number (1st, 2nd, 3rd, final). However, there are also messages for all the way up to "31th race", allowing for a maximum of 32 races. It is likely that this would have been used with a feature for customizing the number of races in VS mode or online tournaments, both of which are locked to 4 races at a time.

Unused Lap Setting

Like in Mario Kart Wii, there is an unused value in the track's settings file which controls the number of laps. Modifying it doesn't seem to affect anything in-game, however. The game only has Lakitu signs for three laps, so it would be unable to properly indicate any extra laps.

Unseen Blue Glider Mushroom

In the award ceremony track (Gctr_WinningRun.szs), there is an unseen blue glider mushroom (like the one in Mushroom Gorge) near the tunnel section on the right-hand side. It is possible to see the stem of the mushroom by using a hack that increases the speed of the karts. It is possible that the mushroom is simply there to allow the winner to glide in from above, as the mushroom looks out of place in Toad Circuit, which the track is based on.

Debug Material

Debug Strings

To do: Check for this content in other regions and versions.

Inside the .code of the European v1.1 ExeFS at 0x4F1A18, there are some references to a debug menu, such as "SndSceneDebug.MapObj", "SndSceneDebug", and "DebugPageList".

There are also a few debug controls:

Debug Option	Button
Exit DebugPageSelect	B
Enter DebugPageSelect	R+B
Select DebugPage	Up/Down

Also, at 0x37B078, where there are all the options shown when finishing a race, there are debug options such as "Debug_Next", "Debug_Reload" and "Debug_Exit"

After a RAM dump, the following debug tasks can be found:

• DebugMenuMainPage
• SoundTest
• DebugShiraiwa
• DebugSuzuki
• DebugObayashi
• DebugKartRun
• DebugField
• DebugSakuraba
• DebugChannelScene

Note that Shiraiwa, Suzuki, Obayashi and Sakuraba are some of the game's main programmers.

Function Symbols

Download Mario Kart 7 (Download Play Child) Symbol Map File: MK7 Download Play Child Symbol Maps.zip (234 KB) (info)

In the download play child application (sent by the game to other consoles in Download Play mode) there is a 1.5MB file called CTRDash.xmap which has all of the 21305 function names and their respective addresses in RAM of the download play executable. Since all of the addresses match the assembly code, the file was probably added or updated with the latest compilation of the child app. Here is a portion of it:

...
30d790	Enemy::AIEngine::stateReady()
30d8b8	Enemy::AIEngine::stateInitIdle()
30d8bc	Enemy::AIEngine::stateInitStop()
30d8c0	Enemy::AIEngine::stateAfterGoal()
30d918	Enemy::AIEngine::stateGhostIdle()
30d91c	Enemy::AIEngine::stateInitReady()
30d968	Enemy::AIEngine::statePlayerIdle()

...

This file can only be found in the European, American and Japanese builds of the game, indicating that this file might have been kept by mistake and only removed in later builds, such as the Taiwanese, Chinese and Korean releases.

Oddities

Lakitu and Shy Guy's Mugshots

To do: Check if this applies to more characters.

	Character select	Trophy screen
Lakitu
Shy Guy

Lakitu and the Shy Guys are the only characters in the game to use different mugshot renders for the trophy screen than anywhere else in the game. For brevity's sake, only the red Shy Guy's mugshots are pictured here.

Download Play Icon

Download Play	Main

The icon used in the Download Play app when receiving data is a crude, early version of the one used for the main game. It is located in the banner folder. This discrepancy was fixed in the Chinese version.

(Source: Original TCRF research)

BGMs

The bgms for the retro battle courses (N64 Big Donut, GBA Battle Course 1, and DS Palm Shore), along with the unlock jingle and the award ceremony winning run, all have the Project Sample Rate (Hz) as 32000, and the rest of the game's bgms uses 32728. This is because these bgms were ripped directly from Mario Kart Wii unmodified, besides winning run being shortened and fading out.

Unusual Item Boxes

To do: Get a better video.

On Rainbow Road. after the first gliding section, there are three Item Boxes hidden under the planet's rings. They can only be collected by flying under the rings and back up onto the course. Unlike the Super Item Box retained in DK Pass (DS), which has a unique item distribution of only speed items and Red Shells, they appear to have no special characteristics.

(video: SuperNickid)

Miscellaneous

Unused Items

The game has two different ways of referencing items. The items that appear in the item roulette (item slots or eItemSlot) and the items that appear in the races as 3D models (item types or eItemType).

Unused Item Slots

There are two test item slots referenced as Test3 (ID 0xF) and Test4 (ID 0x10) with zero probability to appear in any game mode. They display in the item roulette as star items, but since the conversion from item slot to item type is stubbed and the game doesn't have any special code for when the player uses them, they do nothing when obtained and used. These two items actually appear in the item roulette spin animation, as the game just takes a random item slot ID in the range 0x0 (Single Banana) and 0x13 (Triple Red Shells), which includes the test item IDs. This has the side effect of making the star graphic appear more often in the spin animation.

Unused Item Types

The game features 3 unused item types. The first of them is the Golden mushroom (KinokoP, ID 0x08) item type. While this item appears in the game, its behaviour is hardcoded and it doesn't have a 3D model, so the item type is stubbed. The other two correspond to the Fake Item Box (FakeBox, ID 0x07) and Mega Mushroom (BigKinoko, ID 0x0B). All the code and assets related to these item types are stubbed or missing, and only a few references remain in a table that determines how items interact with each other (RaceCommon.szs/ItemReactTable.bin).

Test Kart

Inside a file where there are all the kart body model names, there is a reference to a kart body called "std_lod_oneTest", probably for testing. However, there isn't any model or file with that name. "std" means standard, "lod" means the model is used by the other racers, "oneTest" can mean is the first model is for testing.

Regional Differences

Across different regions, certain tracks and vehicles have different names. These are the names that differ between the European and North American releases, along with a direct translation of the Japanese original (not counting retro courses).

Interestingly, unlike a number of other Nintendo games with separate localizations per region, it's the American script that tends to be more literal and the European script that takes more liberties. Go figure.

Track Names

Japanese	European	American
Kinopio Circuit	Toad Circuit	Toad Circuit
Pukupuku Lagoon	Cheep Cheep Cape	Cheep Cheep Lagoon

Swoop is another name for Swooper in some recent games. The names seem to be used interchangeably. Oddly, the North American name for the Parafoil wasn't carried over to Mario Kart 8.

Revisional Differences

Each update is required to go online.

Version 1.1

Released on May 15, 2012 as a downloadable patch on the eShop. Other than adding "Ver. 1.1" to the Online Multiplayer tab, this update fixed four respawn glitches that could be used to skip parts of several courses during online play:

• GBA Bowser Castle 1
• DK Jungle
• Wuhu Loop / Wuhu Island Loop / Wuhu Island 1
• Maka Wuhu / Wuhu Mountain Loop / Wuhu Island 2

Note that these glitches were only fixed for online play to avoid exploits; in every other mode, these glitches are still present.

The patch itself actually fixes all the respawn glitches, including the ones that can only be done by hacking. Though they are not included in the patch folder, so it's impossible to make them work again online. However, if you were to replace the existing kmp files in the patch with their original kmp, only Maka Wuhu's would work. The Daisy Crusier and Maple Treeway ones were not fixed.

Version 1.2

Released on December 13, 2022 - over 11 years after the original release.

• Adds "Ver. 1.2" to the Online Multiplayer tab.
• Fixes a severe vulnerability in the game's network code that would allow remote code execution. This vulnerability is now known as ENLBufferPwn.

Internal Project Name

Mario Kart 7 is referred to as "CTRDash" internally. "CTR" is the product code for the 3DS.
