The resultant https://archive.org/download/fortressone-demos file browser left a bit to be desired. In particular I wasn't able to sort the files in reverse chronological order.
I wanted a better UI so vibe coded Internet Archive File Browser. It's a single HTML file with embedded JavaScript running on GitHub pages. Works for my purposes. Free and open source.
If you are an open source project and storing files that could reasonably be hosted for free on The Internet Archive this might be useful.
Enjoy.
