Sigpatch-Updater, sorry. And yeah, downloading from that archive.org link gives me this version of the source:Are you looking for sigpatches-updater or Sigpatch-Updater? I assumed the latter one, since you're asking in this thread (ITotalJustice worked on both sys-patch and Sigpatch-Updater)?
Every file is from 2020.
EDIT: It's from version 0.1.3.
