Console8 NPM | npm.io

console8

console8 is yet another chip8 emulator but works on your command line. console8 simply uses your command line to render the graphics and does not require any GUI.

a warning

console8 is an experimental learning project so some roms can be buggy.

I have tested on Ubuntu 19.10 / Lubuntu 19.10 / Windows 10 x64. I am not sure about macOS compatibility.

Rom files are not included with npm installation but you can find some of them in this github repository;
