Our CHIP-8 emulator in Common Lisp is almost complete. It can play games, and we’ve got a rudimentary debugging system in place so we can figure out where things go wrong.
Up to now we’ve been communicating with the running emulator mostly through NREPL or SLIME. This is fine for development, but in this post we’ll add some much-needed polish in the form of menus. This is the kind of boring work that often gets left until the end during game development, so let’s just get it out of the way.
