Here's the reimplementation of my Meta-Machine Code targeted at CHIP-8, written in Common Lisp, released on the third anniversary of its announcement:

There's still work to do, but I'll do so with less stress now. I want to pursue other work, such as writing one of the many Common Lisp libraries I've envisioned, continuing with my Ada programming, etc.; I'd like to start implementing languages this year, but my novel machine text system, Ellision, may steal away much of my time in stead of such.
I don't want to write a long post, so I won't. Feel free to ask any questions concerning this work.
