I wrote this in order to improve my Emacs Lisp skills and to use practically by teaching my sister to program. It is the first elisp program of any substantial complexity I have written, so feedback is appreciated.<p>If you're wondering, Chip-8 did turn out to be a good fit for a beginner. It has limited amount of instructions and is quite graphics-oriented. Having everything inside of Emacs was also quite convenient.
CHIP-8 is culturally relevant today as perhaps the world's first "fantasy console" and precursor to Pico-8, etc. Its instruction set is small, orthogonal, and easy to understand and so perfect for a project like this.<p>Good work! This kind of thing really showcases Emacs as an application platform, able to do a lot with very little code.
