Chip8.js aims to bring CHIP8 emulation to the browser and node.js.
Currently, the demo doesn't support Internet Explorer.
http://reu.github.com/chip8.js
The emulator is almost completely covered with automated tests. You can run the CPU tests using node, with the test task:
$ make test
To run the Keyboard and emulator tests, you must run the suite in the browser.
$ make test-browser
And then accessing http://localhost:3000/test/tests.html URL.
You can also run the tests online by following http://reu.github.com/chip8.js/test/tests.html
The documentation is located in the doc folder, and can be found online at http://reu.github.com/chip8.js/doc
It is generated by YUIDoc, so if you need to update it, make sure you have it installed:
$ npm install yuidocjs
Then, to generate the documentation, just run:
$ make documentation
