I booted this and played with this in VMWare. Played a bit of Snake. I couldn't figure out Wolf3d and the videoplayer didn't play the test video.

I'm not too familiar with Lisp (although I did play a lot with LOGO as a kid), and I suspect if I knew Lisp this would be better. Is this eventually going to be Emacs inside out? Maybe I'll take a deep dive into Lisp sometime as it's ideas are important to the history of computing.

Anyway, keep going.
