    How to play
    1. There is no build to download: get the code from the project's repository.
    2. Build it as its README says. What the build gives, a program to run or the original game rebuilt for an emulator, is written there too.
    3. The project's page says what it needs from your own copy of F-Zero X Expansion Kit, if anything.

From SubmitGame's list, read Oct 21, 2026 and decomp.dev, read Oct 14, 2026, with releases, stars and licenses as each project's repository gives them. The steps are the same for every project of a kind: its own page has the details.

Under the hood: every project behind it, its license and code, how they connect, and who made them.

About

An expansion disk released for the 64DD peripheral that adds multiple additional features when connected to the base game: - 12 new and more difficult courses in 2 new cups, DD-1 and DD-2, as well as an edited cup option. - A course editor, with 100 save slots, similar to the developer tool used to make the game's courses. - A vehicle editor, with 100 save slots, allowed front, rear and wing parts to be combined with different parameters to balance performance - Expanded time attack ghost feature, 3 available for each course - New music tracks and changed audio from mono to stereo - Some of the characters had new higher performance machines available Player created data could be shared/imported but without mouse or online support it was difficult to use. Character portraits might have been editable by swapping data with the Mario Artist 64DD games.
