So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?

The F-Zero X Expansion Kit was released for the ill-fated Nintendo 64DD as a sort-of expansion pack to F-Zero X. Its biggest selling point is a track editor that allows creating new tracks from scratch and saving them to the 64DD disk, 15 years before Super Mario Maker was a thing.

Hidden Images

Some large images of each one of the pilots in the format used by Mario Artist are stored in the F-Zero X Expansion Kit as 216×202 c16 images with a 16×16 thumbnail for use in the menu. They are unused by F-Zero X, but can be viewed by inserting this disc while Mario Artist is running.

GOST is the filetype name for saved ghost data on disk, and CRSD is the filetype name for courses created with the built-in editor.

These messages would have been output while debugging each step of loading a course in Time Attack mode with additional ghost data. In the final version these strings are not linked to code in any way.

File Protection

Fzep-protect.PNG

The file menu in the track editor originally had a protect feature, toggling read-only on a saved course. An unused function at 800F2E4C draws the menu, prints the prompt, and also applies or removes read-only on the file. When applied, other menus will not allow you to rename or delete the file.

There is no placeholder in the structs that build the file menu for an additional entry but there is a gap in the values returned when selecting each option.

0  load
1  save
2  delete
3  rename
4  unused protect feature
5  select course for Edit Cup entry
7  copy

The unused track editor assets in the cartridge games do include a menu image for the protect feature. There is also a text label for the entry in the disk version, as well as prompts and warnings displayed when a file is protected.
