Feature Author Information
JCTC Auto Extractor Jolte0n Allows users to install this distribution directly to your SD card simply by booting the tool and choosing your SD card without any knowledge.
LE-CODE Leseratte This distribution uses the LE-CODE game extension developed by Leseratte.
Custom Track Worldwide XeR Play online in rooms with only custom tracks. The latest version of the patch required for online play.
Wiimmfi Wiimm and Leseratte Support to play on a custom server has been added as a replacement to Nintendo WFC.
Wi-Fi Time Limit Expansion Chadderz This distribution makes a modification to the race time limit on WFC. It has been expanded from 5 minutes to 5:40, allowing longer tracks to be entered and played through to completion. The Nintendo servers have a hard limit of 5:56 before they disconnect everyone, so it is impractical to increase the time beyond 5:40, as the time advances even when looking at leaderboards. If 5:40 is reached, the pack forces you past the leaderboards quickly to avoid disconnection.
Custom Menu System Chadderz This distribution makes use of custom menus to load custom course slots. The cup selection menu is modified with two buttons featuring arrows to the left and right of the main cups. When selected, these buttons cause the current on-screen cup buttons to be replaced with other cups, including custom cups, creating a scrolling menu system. All custom tracks are stored inside custom cups.
Hidden contents opener Kazuki All hidden contents are opened from the beginning.
Change Characters Between Races MrBean35000vr When in online play, the player's character, vehicle and drift mode choice may be changed between races by pressing + on the Wii Remote (or Start on the GCN Controller) when on the VR screen. This simply takes the player back to the character select menu, and then returns them to the vote when they have reselected. If the time limit expires, the currently selected options are taken.
Wi-Fi Timer Chadderz The countdown timer on the Wi-Fi voting screen is always shown now, rather than just when you're about to run out of time. This can give you a better idea of how long you have to make a decision when voting. The time allocated is 30 seconds.
MyStuff Folder MrBean35000vr and Chadderz Allows users to replace certain files with their own, allowing for custom textures, among other things.
Save game on SD Card MrBean35000vr and Chadderz Allows users to save their game on their SD Card, rather than the Wii's NAND.
Auto BRSAR Patching Chadderz, Kazuki and Jolte0n This distribution can automatically make alterations to the revo_kart.brsar file to update the lengths of the game's music files. This means it is no longer necessary to patch revo_kart.brsar when using custom music in the My Stuff folder.
Ghost Blocking mdmwii The game will not save ghosts at all in order to try to prevent save data corruption and accidental overwriting of ghosts. Personal leaderboards are also not updated.
Draggable Blue Shells MrBean35000vr Blue Shells can now be held behind you like Red Shells. They will explode on contact, but not hurt the player. They can be used to protect against other items being shot from behind, but if wheelie-bumped while holding a Blue Shell behind you it will fall away and disappear. Only one Blue Shell can exist at once, so even when it is held out behind you it will be impossible for anyone else to get one from an item box.
Short Thundercloud Kazuki and Jolte0n The duration of smaller size zapped by Thundercloud is shortened.
Speedometer Chadderz, Wine and Kazuki There is a speedometer in the lower right hand corner of the screen, and are 7 choices for its color.
Max Lap Count Modifier Geeh and MrEvil A track can have between 1 and 8 laps.
Speed Modifier! MrBean35000vr Tracks have a speed modifier applied (e.g. 2× speed) which causes all parts of the game's physics to move at the increased speed (including vehicles, items and boosts).
Countdown Mode MrBean35000vr Countdown Mode has been added. On this distribution, it uses its own region instead of replacing the battle region, and it works offline (but some bugs remaining).
Alternative files for the Countdown Kazuki, varemi and Jolte0n Some tracks in this distribution have an alternative version for the Countdown Mode, to avoid from occurring Position Jump Bug or finishing a race in this mode.


The developing team sometimes holds an event at a friend room like mogi, where players compete for their points.
