I got a new RetroPie after a while, and when trying to download some packages (Namely, Daphne and Hypseus) it seems like I get errors where the download links to the files are missing, causing me to get 404 errors, and causing the package to fail to download. I cannot download from the binaries or via source.

Am I shit out of luck? Is there a way to manually install these from a source site?
