Installation
Two options are offered. Download links for each option can be found in the Downloads section.

Tool-compatible option
This option is fully compatible with the MKDD Extender and the MKDD Track Patcher. It includes 16 archives, one for each of the reverse courses.

After downloading and extracting the bundle, use the MKDD Extender or MKDD Track Patcher to patch the ISO file of the game. All regions are supported.

Drop-in replacement option
This option extends Mario Kart: Double Dash!! with 16 extra courses (32 courses in total).

Trivia: This option was the precursor of the MKDD Extender.

First, an original ISO of the game needs to be extracted via 🐬 Dolphin:


 * Launch Dolphin.
 * Make sure that the game that you wish to extract appears in the game list.
 * Right-click on the game, and select Properties.
 * In the Properties dialog, go to the Filesystem tab.
 * Right-click on the root item, and select Extract Entire Disc...:



Warning: If the Extract Entire Disc... option is not present, upgrade Dolphin to a more recent version.

Then, download and extract the MKDD Reverse archive for your desired region (NTSC, PAL, or JAP), and merge all the files in the  and   directories onto the directories of the ISO file previously extracted.

Once the directories have been merged, add the path to the  file into the Config > Paths > Game Folders setting in 🐬 Dolphin. A new entry should now appear in the game list (if file names are visible, it will show the  name). The new entry can be used to launch the extended Mario Kart: Double Dash!! with the reverse courses.

In the game, use  and   in the SELECT CUP or SELECT COURSE screens to switch between the reverse courses and the retail courses.

Changelog

 * Arrow-shaped carpets in Reverse Wario Colosseum have been provided with their correct sound effect. After the arrows were rotated in v12, their sound effect did no longer match the expected "carpet" sound.
 * Some decoration in Reverse DK Mountain (flowers and banners near the starting line) have been rotated to align to the direction of the course. This, too, was an oversight in v12.
 * Fixed an artifact on the ground near the entrance of the first tunnel in Reverse Mario Circuit. This, too, was an oversight in v12.

Changelog

 * Fixed a number of bugs and oversights in the previous release:
 * Fixed BTK animations in Mushroom Bridge and Mushroom City, which broke after last-minute tweaks to the compile scripts.
 * Reversed boost pads and other cosmetic elements in Rainbow Road.
 * Flipped twin statues in Dry Dry Desert.
 * Enabled falling animation in the cliff gap in DK Mountain.

Changelog

 * Reversed road signs, road lights, and all the other cosmetic elements that were left behind in previous releases.
 * Reconstructed staff ghost for Peach Beach (it had gone bad in the v11 release).
 * Controls icon now highlights the left and right arrow in the D-pad in black, to indicate these are the two D-pad directions to switch between retail and reverse courses. This change is only relevant for the drop-in replacement option.

Changelog

 * Enabled pipe shortcut in Reverse Peach Beach.
 * Replaced memory address for temporary data used in Gecko code to fix crashes on GameCube. This change is only relevant to the drop-in replacement option.

Changelog

 * Support for LAN mode. When the course page is changed, the LAN mode's menu are now refreshed too. This change is only relevant to the drop-in replacement option.
 * Minor improvement to the banner (reduced blurriness). This change is only relevant to the drop-in replacement option.
 * Added the  field to the   file. This change is only relevant to the tool-compatible option.

Changelog

 * Sound effect is now played when switching between the reverse courses and the stock courses. This change is only relevant to the drop-in replacement option.

Changelog

 * An alternative bundle compatible with the MKDD Track Patcher (and the upcoming MKDD Extender) is now offered.
 * Relocated extra audio tracks to be more resilient to some ISO-packaging tools.

Changelog

 * Original tracks are no longer replaced. Instead, the game is extended with 16 + 16 courses (32 in total). In the SELECT CUP or SELECT COURSE screens, press  to switch to the reverse courses; press   to switch back to the original courses.

Changelog

 * Added custom banner and custom game title. Thanks to Rand0m-Walk for all the ideas, suggestions, and prototypes.
 * Added custom sound tracks. Original sound tracks have been adjusted to have less bass and more treble, for the purpose of differentiating between the original tracks and the reverse tracks.
 * Minor cosmetic tweaks to course logos.

Changelog

 * Fixed an issue in Yoshi Circuit where karts could enter a dead zone near the exit of the newly added pipe teleport. Reported by Bombchu Link.
 * Fixed an issue in Wario Colosseum where karts could land on a dead zone when they entered the round boost pad from the far sides. Reported by Bombchu Link.
 * Added course preview images.
 * Added course logos.
 * Added course text images.
 * Added staff ghosts.

Changelog

 * Reworked enemy points in all courses. AI can now drift and swerve, and is generally more challenging.
 * Third-person camera view position in steep slopes in DK Mountain and Rainbow Road is now lower, allowing players to see the road ahead. Suggested by Bombchu Link.
 * Fixed a collision artifact in Yoshit Circuit, where karts could hit an invisible wall near the grass area in the crest.
 * Fixed an issue in DK Mountain where CPU karts could get stuck in an infinite loop after falling off the cliff in the first turn.
 * Some cosmetic tweaks in boost pads in Waluigi Stadium and Rainbow Road.

Changelog

 * Fixed regression in collision files introduced in the v2 release. Reverse Wario Colosseum was affected (at least in one place); perhaps other courses were affected too. Thanks to MasterKiller777 for discovering, reporting, and diagnosing the issue.

Known Issues

 * CPU karts won't drift. Enemy point settings are not set currently. To be implemented in upcoming releases.

Changelog

 * Fixed the falling animation issue that affected most of the tracks.
 * Fixed a lap completion issue in Reverse Yoshi Circuit that occurred when the pond shortcut was taken from the very left side (a checkpoint could potentially be missed, breaking lap completion).
 * Improved collision of the wooden fence at the entrance of the bridge in Reverse Dino Dino Jungle. Karts could hit an invisible wall instead of flying over the wooden fence.
 * Other minor tweaks and cosmetic changes.

Known Issues

 * CPU karts won't drift. Enemy point settings are not set currently. To be implemented in the next release.

Changelog

 * Re-enabled alternate paths in Peach Beach, Dino Dino Jungle, and Yoshi Circuit. Firstly raised by RyanDCB.
 * Fixed transparency issues caused by the lack of alpha component in vertex colors.
 * Fixed geometry artifacts caused by a float conversion issue in SuperBMD.
 * Fixed an issue in Waluigi Stadium where karts could be pulled up by the boost pad from the level above when driving underneath the big jump. Firstly reported by RyanDCB.
 * Fixed a crash in Bowser's Castle that occurred when a kart fell to the water near the original wooden bridge. Reported by RyanDCB and AJC276.
 * Slightly flattened the steepest slope in DK Mountain to allow heavy karts to climb the ascent. Suggested by Bombchu Link.
 * Adjusted Wario Colosseum's newly-added cannon to ensure karts can always land on the other side. Reported by MasterKiller777.
 * Other minor tweaks and enhancements in multiple tracks.

Known Issues

 * Falling animation is played by characters when karts take a jump. This is not the case in the stock courses. It is believed to be an issue with the BCO files.
 * CPU karts won't drift, as enemy points have been stripped off all their special settings and flags. (The lack of these settings and flags could be the reason for other unexpected CPU behavior.)

Known Issues

 * CPU karts won't drift. This makes the enemies less challenging. Further investigation on how to get this right required; to be improved in future releases.
 * In the courses that had their BCO file edited, when karts take a jump, the falling animation always plays. It won't matter whether there was a boost pad before the jump; the falling animation always plays. Current theory is that there is something in the BCO files that Mkdd-collision is not yet handling.
 * In the courses that had their BMD file edited, there are geometry artifacts. These are most noticeable in Bowser's Castle, where one can see cracks near the baseboards inside the castle. They are caused by the SuperBMD tool. Some of these artifacts have been fixed manually, but not all.
 * Also, in the courses that had their BMD file edited, there are transparency issues in some textures. These are most noticeable in Waluigi Stadium, DK Mountain, Wario Colosseum, and Rainbow Road. They too are caused by the SuperBMD tool.
