@Andrew I’ve started to experiment with Duet + OpenCore chain loading but I'm getting the same results…

I’ve tested it now on two different Legacy Machines, so either I’m setting it up wrong or Duet is the issue all around the baord… why could Duet potentially not be happy?

It’s not my target system, it’s gotta be something to do with the file structure or the DuetPkg itself, I've also checked for Debug Logs from OpenCore, seems it ain't booting at all, so it's definitely an issue early on.
