What Is the Custom Mario Kart: Double Dash Wiki (mkdd.org)?

mkdd.org is a community-run wiki for custom content in Mario Kart: Double Dash!! — custom tracks, characters, items, codes, and mods. It is useful if you want to find, install, or build custom content for the GameCube game, or if you want tutorials and file-format references for modding it. It is a fan wiki, not an official Nintendo site, and the site itself does not state pricing or login terms for the content it indexes.

What the wiki covers

The main page organizes content into directories and reference pages rather than articles in a single stream. The wiki reports 798 articles. Its main entry points are:

• Mod Directory — the central index of released mods, split into:
  • Original Custom Tracks
  • Retro Tracks
  • Imported Tracks
  • Custom Battle Arenas
  • Track Edits
  • Texture Hacked Tracks
  • Texture Hacked Battle Arenas
• Custom Characters and Vehicles
• Custom Items
• List of Custom Codes and List of Distributions
• Author Directory (user links)

So the site serves two audiences at once: players looking for finished custom content, and creators looking for technical references.

Tutorials and technical reference

Beyond the directories, the wiki hosts a tutorials and reference section aimed at people making content rather than just playing it:

• Installing/playing mods
• Creating custom tracks
• Creating custom characters
• Filesystem and file formats
• Software used in the modding workflow

There are also templates for starting pages — "Make a Custom Track page," "Make a Custom Character page," and "Make a User Link template" — plus a MediaWiki user's guide, FAQ, and a sandbox for practicing edits.

Community and releases

The wiki links to community spaces, including the Double Crew Discord server and an MKDD Time Trialing server. It also maintains a "Latest Releases" feed. Recent entries on the main page include:

Older news is archived by year back to 2020.

Rules and participation

The main page directs visitors to read the Rules and the Published Works Policy before posting; posting on the wiki means agreeing to both. Accounts are handled through a "Log in / Request account" menu, so contributing requires an account request rather than open editing.

When it is the right resource

Use mkdd.org if you want a single index of Double Dash custom tracks, characters, and codes, or if you are learning to create that content and need tutorials and file-format documentation. If you are looking for official game information or unmodified gameplay guides, this is not that kind of site — it is built around custom and modified content maintained by the community.
