Mario Kart: Double Dash!!

Mario Kart: Double Dash!! is a racing game developed and published by Nintendo for the GameCube and the fourth installment of the Mario Kart series. It was released in November 2003 worldwide, being released in Japan first. The game, while retaining many aspects of previous Mario Kart games, such as selecting a Mario franchise character as the player's driver and the familiar item-based weaponry that the series employs, introduces a feature that is unique to this entry in the Mario Kart series: the two-person karts, hence the title of the game. Two characters handle a single kart, where one character steers and the other deals with items, and they can switch positions at any time if necessary. The game is the only game in the franchise where two players can play cooperatively in one kart, with each player handling a single character, though the option to play in separate 2-person karts for each player is still available. In addition, the game introduces Special Items, items that are exclusive to a pair of characters, which is another feature unique to this game. The game is one of the few games to take advantage of LAN Mode via the Nintendo GameCube Broadband Adapter, which allows up to sixteen players to participate in a single race.

Mario Kart: Double Dash!! is the first Mario Kart game in the series to employ 3D graphics for characters and items, as opposed to Mario Kart 64 using pre-rendered sprites to display these objects. The game also introduces a larger variety of karts to select from depending on the character combo's weight class rather than the standard go-kart being the sole vehicle all racers use, and this variety of vehicles is retained in all Mario Kart games since.

New features
As with every new Mario Kart game, Mario Kart: Double Dash!! shows several new features, granting a new style of playing for the users. Apart from that, there are two characters per kart; the number of playable characters was increased to join the race. As implied in various Mario series games, Mario Kart: Double Dash!! contains many elements to unlock as well. By beating the cups available in every engine level, the player unveils other hidden levels, karts, and other playable characters in the game. Furthermore, there is a very dynamic selection of karts: Every kart has specific stats that distinguishes from the others, as well as capturing their respective character's style; for instance, Mario's kart, the Red Fire. In the first three games, there was only one kart that the players could use, which was what Mario Kart 7 would eventually call the Pipe Frame.

Items are the main element presented in every Mario Kart game, and Mario Kart: Double Dash!! is no exception. These are obtainable via Item Boxes, where characters can receive any standard Item or a Special Item. The latter is an item that a specific pair of characters can receive, while all others cannot. Additionally, power-ups dropped on the course will instantly effect the kart that would pick on it as a Banana, a Koopa Shell or a Mushroom or Star. The effects of certain items have changed considerably as well.

Another notable change featured in the game is the point system given to the racers after a competition in Grand Prix mode. Starting from Mario Kart: Double Dash!! onward, this new system is used for the newer Mario Kart installments that were developed after this one. Also, players cannot retry a failed race in Grand Prix mode, as opposed to the first three games. Users have to continue racing until finishing a cup to see the overall results. The following chart shows the difference of the point spreads from previous games to Mario Kart: Double Dash!!.

This is also the first Mario Kart game to feature live-rendered 3D models for the characters and items, whereas in previous Mario Kart games, the characters and items are pre-rendered sprites.

However, more than the new point system, Mario Kart: Double Dash!! also added important features that would become mainstays of the future Mario Kart titles. For example, before the start of every race, a short overview of the track, lasting a few seconds, shows all of the big features of the track, such as obstacles, scenery, and the finish line. Also, the countdown to the start of the race lasts for one second longer; in Double Dash!!, the countdown is "3, 2, 1, START," while in the first three games, it is represented by two red lights followed by a green light.

Characters
Because of the team mechanic, Mario Kart: Double Dash!! includes 20 playable characters, with nine returning characters and 11 newcomers, the second most introduced in any Mario Kart game. The game also introduces Toadette to the Mario franchise. This is the only Mario Kart game to feature more playable characters than it does race courses. Characters are divided into three classes depending on their weight: Light, Medium , and Heavy. There are eight default teams and two unlockable teams, a total of ten teams and twenty individual characters which can be combined in any way, giving 190 possible character combinations. Pressing and  together before selecting any character will choose a random pair of characters and a random kart to play as. In multiplayer mode, it'll randomize everyone's character and kart.

Unlockable teams

Supporting characters
In addition to the playable drivers, numerous other Mario series characters play supporting roles in the game as well. Lakitu reprises his role as the referee, meaning that he signals the start of each and every race and battle with his starting lights, alerts players when they complete a lap around the course, tells the drivers when they're going in the wrong direction, waves the checkered flag to finish the race at the finish line, and returns drivers to the track if they land themselves in a dangerous predicament (i.e. falling off the course). Other characters who make cameos include Shy Guys, Piranha Plants, Cataquacks, and Dinosaurs. Toadsworth drives the winners of a cup around Peach Beach in the Parade Kart. Piantas and Nokis from Super Mario Sunshine cheer the racers on in some courses and join them during the Award Ceremony.

Game modes
Mario Kart: Double Dash!! contains sixteen new racing courses added, along with six new battle courses. Each racecourse contains its own difficulty and gimmicks. Up to four players can play in all the modes, excluding Time Trial mode, where only one is permitted. In addition, the users can play independently or in cooperative mode, a unique style of gameplay only featured in Mario Kart: Double Dash!!.

Grand Prix
In Grand Prix Mode, the player needs to win the cups against computer-controlled opponents. The difficulty level against CPU racers changes in each of the four engine classes, which are the following:
 * 50cc - Easy. The minimum top speed is low for all karts and CPU racers have a very limited selection of items. Any kart will take the 1st and 2nd place positions.
 * 100cc - Normal. The minimum top speed is fairly average, while CPU drivers have a wider selection of items: they may use Red Shells to shoot it to the player in front of them. Lightweight karts are never in the top positions (when controlled by CPU).
 * 150cc - Hard. The minimum top speed in the karts is high, and CPU drivers have a wider selection of Items, most notably, the Spiny Shell's addition. In this level, CPU drivers can take down players using the items against them. Additionally, all characters race in mixed teams. CPU-controlled heavyweight karts usually take the top positions, with middleweight cars very rarely taking the top positions (when controlled by CPU).
 * Mirror - Very Hard. Similar to 150cc engine class, however all the tracks are mirrored. CPU-controlled heavyweight karts usually take the top positions, with middleweight cars very rarely taking the top positions (when controlled by CPU). This engine class is not unlocked until players beat the All-Cup Tour in 150cc.

There are mainly four cups in Grand Prix mode, each one with four stages to race. These cups bear their difficulty levels as well as the race courses within. The most basic is Mushroom Cup with simple courses and few gimmicks. Special Cup, on the other hand, contains long and gimmicky race courses. All the race courses have three laps, except Baby Park, which has seven because of its short length, and Wario Colosseum, which has two due to its great length.

Special Cup is an unlockable cup. It is unlocked when players beat 100cc Star Cup.

A fifth cup, the All-Cup Tour is the conglomeration of all the cups in the game. It is unlocked after players beat the Special Cup in 150cc. The 16 tracks are played through one after another in random order, with the exceptions of Luigi Circuit always appearing first and Rainbow Road always appearing last. This cup does not appear in other racing modes.

In GP Mode, two players can join a race, as themselves or in Co-op play. Players can play Grand Prix mode with two players in different karts or in co-op mode for two to four players.

Time Trial
In Time Trial, a single player races courses over a set number of laps to record the fastest completion time. Before racing, adding the player's name entry will register their records available. When a race starts, the characters will have two mushrooms in hand for speed boost. The best time elapsed in a lap and a race on a specific track will be saved after completing the race. Once a race is completed on a course, the user is able to compete against either their Ghost from the current Ghost data or the Staff Ghost within the stage. Otherwise, if a race is failed, the Ghost data will not be saved. The Ghost data recording can be disabled in the Options screen menu. Each Ghost save is worth five blocks on the GameCube Memory Card.

In Japan, players were able to submit special codes in Time Trial mode as part of a contest. The content never existed outside of Japan, but the results of the code can still be accessed in all versions of the game.

Battle
Battle Mode is a traditional mode that has presented throughout all Mario Kart games. Two to four players can compete against themselves using a variety of items (including all the special items) on the new battle arenas found in Mario Kart: Double Dash!!.

In Battle mode it is possible to play in three sub-modes:

Names in other languages

 * Balloon Battle


 * Shine Thief


 * Bob-omb Blast

Versus
Versus (for two to four players) allows racers to select their characters and karts, and compete among themselves on the tracks. It's also possible to play in versus mode through a LAN connection where more than four players can join a competition. Additionally, there are some versus options found in the Option menu to change the mode's gameplay:
 * Number of Laps: The number of laps set over all tracks, ranging from one to nine. If one lap is chosen, the beginning of the race will start as a Final Lap with Final Lap fanfare music.
 * Items: The variety of items given to the racers can be changed to:
 * Recommended: Default way in obtaining certain item by racer's place.
 * Basic: Powerful items like lightning bolts or stars are rarely obtainable.
 * Frantic: Items such as bananas and green shells are absent.
 * None: No items to use at all.

Co-op play
Supporting the main feature in Mario Kart: Double Dash!! upon two-racers-one-kart, Cooperative Play (also said Co-op Play) lets two players control their respective character in a kart, one being the driver and the other as the item thrower. While playing in Co-op mode, the players' characters can perform special moves that a single player cannot make. The rear character can perform a Slide Attack to steal an item from their rivals while messing up the rival's vehicle's controls. Both players can even double the power of the Rocket Start by pressing the button at the same time. This special boost is the Double Dash.

The following table below excludes Time Trial as it is a single player exclusive mode.

Karts
Twenty-one karts are available in Mario Kart: Double Dash!!, notable for having different designs and appearances. There is one kart for each character, plus the Parade Kart. Every kart has three ratings, rated by the number of stars. The maximum amount is five.


 * Acceleration: How quickly a kart can achieve its top speed.
 * Speed: The level of top speed when the kart goes forward.
 * Weight: The weight of the kart.

Just as the characters are classified according to their weights, karts are split into three groups in size with some general characteristics:


 * Light: Lightweight karts show a nice acceleration but poor top speed and low weight. They can be easily bumped away by heavier karts. They do not lose a lot of speed when they go off course.
 * Medium: Medium-weight vehicles show average top speed and acceleration. Some karts within this group have slightly varied stats, though.
 * Heavy: Heavyweight karts have the highest level of weight among the karts, capable of knocking away light and medium-weight vehicles. Many of these show high top speed, although their acceleration and off-road are fairly poor.

Each combination of characters will also determine the class of kart that will be used for the race. The table to the top right means the resulting vehicle according to the size of the characters. An exception to this rule is the Parade Kart, which all the characters, regardless of weight, can drive. It is unlocked by completing All-Cup Tour in Mirror Mode.

Kart stats
These are the kart stats that are displayed in-game.

* is unlockable

Actual stats
The stars shown on the vehicle selection screen are less precise than the actual values used by the game ; Speed and Weight each have 9 distinct values rather than 5, and the differences in Acceleration are mainly due to two values, generating 9 possible combinations that don't necessarily line up with the menu stats: the first value affects mainly the first phase of acceleration while starting from a standstill, the second affects acceleration when the speed is higher than around 50% of the maximum speed. When drifting, acceleration depends on values that are the same for all karts. Drifting itself can begin when the speed of the kart is at least 15 km/h (26 units). When the speed is lower than that, trying to drift results in the kart having an acceleration value proportional to the first acceleration value but considerably smaller than that. It is also important to note that the values determine acceleration in terms of increase of relative speed, the fraction of current speed to top speed, over time.

Speed is reported in units, from which the values in the speedometer are calculated using the following conversion factors :

Skm/h = Sunits / 1.75

Smph = Sunits / 2.5

Speed is actually capped at 175 units (100 km/h, 70 mph).

Furthermore, there's a hidden Off-Road stat that determines a vehicle's top speed in most off-road terrains, such as grass. Weak off-road patches, like the yellow sand in Dry Dry Desert, reduce the kart's top speed by a fixed 20 units (~11 km/h, 8 mph). On the other hand, middle off-road patches, such as the grassy and sandy part where the Chain Chomp lies in Luigi Circuit, reduce speed to a value dependent on the kart chosen. Finally, heavy Off-Road areas such as the reddish sand in Dry Dry Desert or underwater parts, slow down all karts to a fixed 40 units speed (23 km/h, 16 mph).

When shrunken by Lightning, the top speed in normal roads and weak off-road sections goes down by 20 units, while the top speed in medium off-road sections goes down by 10 units. The top speed in heavy off-road sections stays unaltered.

All karts have their own Mini-Turbo value, however all light karts have a Mini-Turbo boost that lasts 30 frames, all medium karts have a 20 frames Mini-Turbo boost, and all heavy karts have a 10 frames Mini-Turbo boost. Interestingly, the Parade Kart has a Mini-Turbo boost that lasts 30 frames.

Staff Ghosts
This game follows Mario Kart 64 in including the possibility to race against Staff Ghosts, ghosts created by Nintendo staff as the main ghosts of the course. They can be unlocked by achieving a certain time on the respective course. Below is a table showing all Staff Ghosts and their respective times.

Items
Traditional items from Super Mario Kart through Mario Kart: Super Circuit appear in Mario Kart: Double Dash!! with a bunch of new power-ups to change a race drastically, such as stealing the opponent's place or item by using a Mushroom or reducing the racers to small size with the rare Lightning. The rear character obtains a determinate item by running into an Item Box. However, Double Item Boxes give items to both the rear character and driver. The variety of items depends on the kart's place. Leader racers tend to receive basic items such as Bananas or Green Shells, while those going under fourth place can receive rare items like a Star or a Spiny Shell.

Items are classified in two forms:
 * Standard: Drivers can obtain these types of items when they go through an Item Box or Double Item Box.
 * Special: Some drivers obtain a special item that other drivers cannot obtain by an Item Box. When a character holds a special item, the second character cannot obtain another special item via Item Box.

Special Items

 * Petey Piranha and King Boo have the ability to obtain any special item, excluding Green Fireballs and Birdo's Egg.
 * Note: Although special items can only be obtained by the characters they are assigned to, if a player is holding a special item, another player can steal it by colliding with the player holding the item while under the influence of a Mushroom, Star, or Slide Attack. Also, any character can get any special item in Battle Mode. Finally, in Co-Op Mode, the driver can pass a special item to the person in the back.

Drifting and mini turbo
Drifting prevents racers from losing speed in turns or from going off the course. By keeping pressed the controller's button (or  button), and tilting the stick to sides, racers make the kart turn around. While drifting, racers can gain a momentary speed boost by tilting the control stick to the sides, opposite to a corner's direction. The kart then produce sparks on its wheels. Doing this two times more, racers make the sparks become orange, then blue, and then releasing a mini turbo right after the racer lets go of the (or ) button.

This tactic can be used to perform the snaking (continuous power sliding) and elude homing hazards such as Red Shells.

Rocket Start
A Rocket Start is a speed boost given to a kart when a race starts out. To perform, racers just have to press the button to accelerate right when Lakitu's lights turn green or by tapping the button repeatedly while Lakitu counts down.

Double Dash
The Double Dash is similar to the Rocket Start. Although it is more powerful, it can only be performed in Co-op play. Both team members can press the button at the same time when Lakitu's light turns green. Upon being done perfectly, the kart bolts farther, leaving out a blue flame as a result. This technique is named after the game's subtitle.

Item steal
Item stealing is snatching a power-up directly from the rival's hands in a kart. There are three ways to steal an item as long as the player's rear character holds no items. Items can be stolen when the rear racer uses a mushroom or a star to hit an opposing kart and snatch the item that one of the rivals have. In Co-op Mode, the player's rear character can use the Slide Attack to knock other rivals and take their items away. However, if the rear character knocks a rival kart with two players holding an item, the character can get the rival rear character's item, while the rival driver drops the other item onto the track.

LAN Mode
Using the Nintendo GameCube Broadband Adapter (sold separately) attached to the game system, in Mario Kart: Double Dash!! it is possible to play via Local Area Network (LAN), using up to eight Nintendo GameCube systems connected to a hub device, or also using two consoles connected together through a cross-cable, where more than four players can join a race locally. This means that up to sixteen users can play at the same time with their friends using two or more GameCube systems with the Mario Kart: Double Dash!! game discs on.

After connecting the systems to the hub, the players should turn the systems' power button to begin. The LAN Mode option appears on screen to confirm the selection. Once LAN Mode is selected and confirmed on all participating game systems and the connections have been established, the Select Mode displays. Players may proceed by pressing controller's button, the LAN Mode title screen displays to enter to play.

In the LAN Mode title screen there are three options:


 * Start Game: Begin Versus LAN play.
 * Select Mode: Adjust LAN setup options. This allows to the users to choose the modes of play:
 * Game Mode: Select one of these game modes available: Versus, Balloon Battle, Shine Thief, or Bob-omb Blast. Only in Versus mode the number of laps on the tracks and the engine classes can be changed.
 * Order of Courses: Choose the way in which courses or stages will be selected: Random, All courses, one course or All-cups (only for Versus)
 * Co-op: Enable or Disable Cooperative Mode
 * Screen Division: This option won't be available if there is more than four Nintendo GameCube systems in use.
 * Quit LAN Mode: Stop playing LAN Mode

Unlike the local multiplayer, the players' characters are chosen at random, each time a race begins.

Toad and Toadette can be selected, providing they have been unlocked on one of the memory cards. Petey Piranha and King Boo however are never picked, even if they have been unlocked on one of the memory cards.

The karts that are picked is the one that belongs to the driver. If their respected kart has not been unlocked on one of the memory cards, then they use their respective partner's kart (e.g. Luigi uses Mario's kart). The exception is that if a small character is paired with a large character then the large kart is used instead. This means the Piranha Pipes, Boo Pipes and Parade Kart can not be used in LAN mode.

LAN connection
In this way, two to eight Nintendo GameCube systems are connected to an over-the-counter 10BASE-T hub. The LAN cables used to connect every game system to the hub must be compatible, otherwise, the connection won't be carried out. Every Nintendo GameCube system has to have attached their Nintendo Broadband Adapter, and the Mario Kart: Double Dash!! game disc in hand, one per system. At last, the number of GameCube controllers used depends on the number of players present.

Cross-cable connection
Unlike LAN connection, where it uses a hub to connect GameCube systems to it, the Cross-cable connection requires of only two GameCube game systems connected between themselves, through a 10BASE-T hub-compatible cross-cable. The rest of the required equipment is similar: A Mario Kart: Double Dash!! game disc per system, the Nintendo Broadband Adapter attached to the game system, and the number of GameCube controllers regarding how many players participate.

Differences in split-screen races
There are several differences that players can notice in split-screen mode, most likely to preserve the frame rate. In Dolphin's Netplay online mode, the single screen features are featured in split-screen races. In future Mario Kart games, however, split-screen mode no longer omits track features.

Pre-release and unused content
The models of the characters are from Super Smash Bros. Melee, and Mario and Luigi are seen in this trailer of a very early build of the game, driving separately, each in a simple, blue kart.

Donkey Kong Jr. was also seen in an early build of the character selection screen, but was scrapped in the end.

Critical reception
The game received favorable reviews, getting an average score of 87.20% in GameRankings based off 73 reviews and an average score of 87 based off 58 reviews in Metacritic.

Spencer McIlvaine of Nintendo Life gave the game 9 stars out of 10, praising the game as being a worthy successor to the Mario Kart franchise, despite that it has less innovation than the other games. He concluded with "Nevertheless, the game has lost some of the edge that it had in its first two outings and shows fewer innovative ideas here. This time around the game was mostly about better graphics and less buggy programming with a few gimmicks thrown in like having two drivers instead of one. As a result, Double Dash is not the most recommended Mario Kart game in the franchise. But compared to other games in general it’s still one heck of a ride." Tom Bramwell of Eurogamer gave the game a score of 9 out of 10. He praised the game for adding more content, especially the online LAN mode. He wrote, "In my opinion, it's not a better game than the original Super Mario Kart, but it is the closest anyone's ever come, and one of the finest pieces of electronic entertainment ever developed." He also stated that rating Mario Kart Double Dash!! was the hardest thing he did because he always wanted to write about it.

On the contrast, Edge Magazine UK gave the game a 5 out of 10, criticizing the game of "not being a racing game any more". Fran Mirabella III of IGN gave the game a score of 7.9 out of 10. He criticized that Mario Kart Double Dash!! felt very similar to Mario Kart 64 and although it gets the job done that it felt that it had wasted potential. He praised the multiplayer for being superb.

Sales
Mario Kart: Double Dash is the 2nd best-selling game for the Nintendo GameCube, right behind Super Smash Bros Melee, with approximately 7 million copies sold, including 3.8 million copies in the United States, and over 802,000 units in Japan, as of December 31, 2009.

Permanent upside-down car
This glitch only works with the Parade Kart. The player should go to a place where they can get smashed by the course obstacle, such as the Thwomps in Bowser's Castle or the blue dinosaur in Dino Dino Jungle (Bowser's Castle is preferred because the Thwomps are stationary). This glitch best works for two players, as timing is needed. One player should drive underneath a Thwomp, while the other should receive an explosive power-up, either a Spiny Shell or a Bob-omb. When received, the player should fire the item at the correct moment, blasting the kart into the air and getting smashed under the floating Thwomp. After falling down, if done correctly, the player will remain such, which is upside down. Note that the player is invincible in this position and the player can only revert to normal position if Lightning strikes them and a Thwomp afterward.

References in later games

 * Later Mario Kart games: Mario Kart: Double Dash!! is known to have set the standards for later games in many ways. The 3-second countdown, which was introduced in this game, was reused in all later Mario Kart games. This is also the first game to have its final lap music one key note higher. This also marks the first time the player loses an item after falling off the course or being hit by certain items or obstacles. The Bob-omb item that was introduced as a Special Item for Wario and Waluigi in this game became a regular item in later games.
