Original thread announcing the leak: https://boards.4channel.org/g/thread/89060767
Internet Archive link to .zip file snapshot of files from GitHub (but no git commit history): https://web.archive.org/web/20221007235925if_/https://codelo...
Also mirrored here: https://git.tcp.direct/TheParmak/ICE_TEA_BIOS
The git bundle for that mirror is also on the Internet Archive: https://web.archive.org/web/20221008155117if_/https://git.tc... (which can be restored via the instructions at https://git-scm.com/book/en/v2/Git-Tools-Bundling)
Note that downloading the git bundle (from the link on git.tcp.direct or its mirror on Internet Archive) is the most space-efficient download, as there are many large identical files in the repo that git deduplicates but the zip file format does not.
