I recently wrote a CHIP 8 interpreter using JavaScript to brush up on my skills and learn some new features. I was able to improve upon a previous Python version and noticed that there isn’t much difference in performance in this case. However, I know that I can significantly speed up the JavaScript interpreter.
See my CHIP-8 Live Demo on Github. Enable the NUM LOCK and use 4 / 5 / 6.
Because JavaScript allows for fast prototyping, I was able to easily add a live monitor and disassembler. I wish I had more time to write my own assembler and some CHIP 8 programs, but I’ve moved on to a different project for now.
Check out the working CHIP8 code on GitHub, online version in the future.
Everything looks fine, now I’m gonna fool around. And so, reworking this into Javascript helped me to optimize the Python version #js #javascript #chip8 #emulator #interpreter #spaceinvaders #retrogames #retrogamer #codingisfun pic.twitter.com/W7K61FMJEs

This clip below shows the moment I was hunting a bug causing problems with the .PC register, jumping out of the program scope. Despite the fact I already had my Python version, due some language differences I couldn’t track it down for a few hours.
