I've been working on getting a static site for testing this out more automated-y. I wrote a gameboy advance emulator in JavaScript and have been working on it for a bit. Thought I'd share it, even though it's kinda random.

You'll need Firefox, preferably version 26 or 27.
There are better options for playing GBA on a computer though. I'm more interested in seeing your code, if you don't mind. :P
