As for cracktros, probably not. I should spelunk through backups. However, the most technical and competitive people generally transitioned to the demoscene in the early 2000s and that scene is far more open.

You can find a lot of groups/individuals publish a lot of esp. their older stuff now.

Two off the top of my head:

- https://github.com/ConspiracyHu (and they made a W32 port of Future Crew's Second Reality, which is public domain: https://github.com/mtuomi/SecondReality)

- Farbrausch published their original demo tool source ages ago: https://github.com/farbrausch/fr_public
