If someone has a recent archive of the git repo I'll happily add it onto my git server.

Edit: nevermind I found git bundles on archive.org, so now skyline is here. I've also set up mirrors for some of the other skyline-emu repos but those are probably safer

Edit 2: fixed typo and add link to skyline-dev. Also did you know you can access the GitHub repo's old commits if you know/guess a commit? https://github.com/skyline-emu/skyline/tree/bdf73aa20d4fffc41e7be4ad906521c920ab68c0
