With https://github.com/SpiritQuaddicted/quake-code-archives I try to archive public VCS repositories of any Quake related projects.
Enjoy ~30GB from yesterday’s update: https://archive.org/download/quake-code-archives_dump_20210719/quake-code-archives_dump_20210719.tar.zstd
If you spot anything broken, please shout.
And if you spot missing repos, please add them.
