This is a small RISC-V emulator I’ve been hacking on in Emacs Lisp as a fun weekend project.

It started mostly as a way to better understand the RISC-V spec by implementing things myself, and also as an excuse to write more non-trivial Emacs Lisp. It currently focuses on RV32I and related basics, and is very much not optimized or production-ready.

If you’re into RISC-V, emulators, or just enjoy seeing unusual things built in Emacs Lisp, feedback and comments are welcome

Happy hacking!
