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 JPN (Found in the CIS-004 Harddrive), 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.

Unused Audio Lots of early sounds and ambience.

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

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

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 E3 2010 autodemo. 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.bin 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 entries 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.

To do: Differences between MovingRoad, MovingRoad1 and MovingRoad2. UgTreeL and UgTreeS have code associated to them.

Name (ObjFlow.bin)	Name (Code's class)	Object ID	Notes
ef_env_sun	ObjectOldSun	0x002	Unused sun object, leftover from the E3 2010 demo. Its only unique code (function "Field::ObjectOldSun::initObj") forcefully disables the object and makes it invisible. A comment associated to this object in the code reads "old sun( to be delete )".
jugem	-	0x009	A Lakitu object. When placing this object, it doesn't use the Lakitu model from RaceCommon.szs, but rather it loads it from the track szs, and without animations (due to there not being code specifically for this object), so it's just placed in a T-pose.
RrStarRing	ObjectStarRingJmap	0x011	Unused Star Ring. It inherits its code from the used Star Ring, but otherwise has no unique behaviour that's different from the used variant. The used one's ID is 0x17F.
MovingRoad	ObjectTwistWay	0x012	Unused moving road.
MovingRoad1	ObjectTwistWay1	0x016	Unused moving road.
MovingRoad2	ObjectTwistWay2	0x015	Unused moving road.
WiiCarB	ObjectFixedWiiCar	0x06F	Removed car object for Wii Coconut Mall. This one was meant for the cars parked in the parking lot (similar to Mario Kart Wii since those were objects), but these were moved to the track model, as the texture name for them are Wiicm_CarB.
CruiseShip	-	0x073	A removed cruise ship object. This was probably a background object.
WiiCarA	ObjectWiiCar	0x07A	Duplicate of Parking Car Variant A, but without collision.
DsSkyCastle	-	0x14A	Removed Sky Castle object. Meant to be a background object for DS Airship Fortress, since a texture name in the track model uses ds_skycastle, which is for the castle and airships in the background.
WiiParasol	-	0x15A	Removed Parasol object. Possibly meant to be a decoration for Wii Coconut Mall.
CmnTree1	ObjectCmnTreeNoHitCmnTree1	0x169	Duplicate Tree Variant 1, but without collision. The used one has object ID 0x130.
CmnTree2	ObjectCmnTreeNoHitCmnTree2	0x16A	Duplicate Tree Variant 2, but without collision. The used one has object ID 0x133.
CmnTree3	ObjectCmnTreeNoHitCmnTree3	0x16B	Duplicate Tree Variant 3, but without collision. The used one has object ID 0x157.
CmnTree4	ObjectCmnTreeNoHitCmnTree4	0x16C	Duplicate Tree Variant 4, but without collision. The used one has object ID 0x149.
CmnTree5	ObjectCmnTreeNoHitCmnTree5	0x16D	Duplicate Tree Variant 5, but without collision. The used one has object ID 0x15F.
WiTree1	ObjectCmnTreeNoHitWiTree1	0x16E	Duplicate Wii Tree Variant 1, but without collision. The used one has object ID 0x134.
WiTree2	ObjectCmnTreeNoHitWiTree2	0x16F	Duplicate Wii Tree Variant 2, but without collision. The used one has object ID 0x135.
WiTree3	ObjectCmnTreeNoHitWiTree3	0x170	Duplicate Wii Tree Variant 3, but without collision. The used one has object ID 0x136.
DsDeadTree	ObjectCmnTreeNoHitDsDeadTree	0x171	Duplicate dead tree from DS Luigi's Mansion, but without collision. The used one has object ID 0x14D.
DsSpookytree	ObjectCmnTreeNoHitDsSpookytree	0x172	Duplicate spooky tree from DS Luigi's Mansion, but without collision. The used one has object ID 0x156.
GcTree1	ObjectCmnTreeNoHitGcTree1	0x173	Duplicate GC tree, but without collision. The used one has object ID 0x161.
MrBush	-	0x179	Removed Bush object for Cheep Cheep Lagoon. This was probably the seaweed, which is part of the track model instead. Although according to the file GeoHitTableKart.bin, this object is solid and uses the same collision as a normal tree. The seaweed isn't solid in the final, so either they were at some point (which wouldn't make much sense considering tricks were probably implemented at this point), or this was the bushes at the start of the track, which is out of bounds.
IsAnemone	-	0x185	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.
RrMovingRoad	ObjectRrWaveWay1	0x186	Unused Moving Road for Rainbow Road.
UgTreeS	ObjectUgTreeS	0x194	Removed Small Tree for Piranha Plant Slide. Most likely removed since the trees are part of the track model rather than objects.
UgTreeL	ObjectUgTreeL	0x195	Removed Large Tree for Piranha Plant Slide. Most likely removed since the trees are part of the track model rather than objects.
SfcMovingRoad	-	0x19B - 0x19E	4 unused versions of the SNES Rainbow Road moving roads.

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()

30dbb4	Enemy::AI::startKiller()
30dbdc	Enemy::AIEngine::awake()
30dc88	Enemy::AIEngine::sleep()
...

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

To do: Is the icon stored in the Download Play ROM header not used?

Download Play	Main

The icon for the Download Play ROM (which is displayed by the 3DS Download Play app), early version of the one used for the main ROM (which is displayed on the home menu and in data management). 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, the watch race bgm, 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 (except the watch race bgm, which is very likely a leftover from the E3 2010 build), 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
Heiho Carnival	Shy Guy Bazaar	Shy Guy Bazaar
Wuhu Island 1	Wuhu Island Loop	Wuhu Loop

Wuhu Island 2	Wuhu Mountain Loop	Maka Wuhu
Rosetta Planet	Rosalina's Ice World	Rosalina's Ice World
Koopa Castle	Bowser's Castle	Bowser's Castle
Honeybee House	Honeybee House	Honeybee Hive

Despite the name change, the Japanese and North American name "Music Park" can still be seen on banners in the level in the European version.

Kart Bodies

Japanese	European	American
Gold Kart	Gold Kart	Gold Standard
Birthday Girl	Royal Ribbon	Birthday Girl
Mach Queen	Bumble V	Bumble V
War Beetle	Growlster	Bruiser

The Japanese version also calls this kart part a frame rather than a body.

Kart Tires

Japanese	European	American
Normal Tire	Normal	Standard
Gold Tire	Gold Wheels	Gold Tires
Roller Tire	Roller	Roller
Ring Tire	Slim	Slim
Slick Tire	Slick	Slick
Sponge Tire	Sponge	Sponge
Super Kinoko	Mushroom	Mushroom
Wood Ring	Wooden	Wood
Wild Red	Monster Red	Monster Red
Wild Tire	Monster	Monster

The European version also calls this kart part a wheel rather than a tire.

Kart Gliders

Japanese	European	American
Super Kite	Super Glider	Super Glider
Gold Kite	Gold Glider	Gold Glider
Flower Kite	Flower Glider	Flower Glider
Beast Kite	Ghastly Glider	Beast Glider
Basa Basa Kite	Swoop	Swooper
Parafoil	Parafoil	Paraglider

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.
