A year ago, I worked on some custom F-Zero X tracks. For those who don't remember, the Nintendo 64 had an add-on in Japan called the 64DD and F-Zero X Expansion Kit eventually came out too, allowing you to make your own tracks. However, these things are super rare and expensive. However, on the internet, here's F-Zero Execution Project (FZEP), which lets you make F-Zero X tracks and export them into ROMs. It's friggin hard to use because of the incompatibility problems that can occur if you do your tracks wrong, but it was still fun to mess around sometimes.
For those who don't mind learning how to actually put these tracks in a ROM using FZEP or just want to mess around with them, I uploaded them for your pleasure.
These tracks are special in a particular way: like Baphemetis custom tracks, my tracks were designed for use with the action replay/game shark code that makes your car go at 2000 Km/h instead of the usual 800 Km/h. That speed code comes with most versions of Project 64 and can also be found on cheat sites. The code is called Super Ultimate Mega Fast. The circuits I made are extremly hard, and you will have to retry and retry many times for sure. Unlike Baphemetis, I did not hack codes into the ROM, and his ROM was made so turning is much faster, which isn't the case of my tracks, which are to be inserted in a clean google-searched F-Zero file which we won't provide. You can also fly through entire tracks with that code, altough this might be hard to do with mine. Anyway here they are below and I included videos of most of them:

EDIT: Added video for 4th track
