 To use this project you'll need to provide it with a canvas element, styled as necessary so that it has the correct size on screen (the program will be scaled up automatically to fit, controlling for aspect ratio). You will also likely want to provide a simple UI for entering full-screen mode or muting the audio; these can simply call methods on the emulator when activated.

 Loads the emulator for the Atari 2600 console, and an image of a catridge for Pitfall. Notice how we download the image, storing it in a file, then set up a "cart" peripheral so that the emulator can find it. We also load a configuration file that preconfigures some keybindings needed to use the 2600.

-# Configuration API #
+## Configuration API ##
 
 Currently there are two supported emulators, JSMESS and EM-DosBox. JSMESS provides emulation for arcade games, consoles, and early personal computers. As this emulator supports such a wide variety of hardware it has been broken up into several dozen emulators each supporting one machine lest the resulting javascript be intractably large (60+ megabytes). EM-DosBox provides emulation for software that runs on x86 PCs using the DOS operating systems common to the era.
 
 Each of these is configured by calling a constructor function and providing it with arguments formed by calling static methods on that same constructor.

 There's also a helper for loading software from [the Internet Archive](https://archive.org/v2), `IALoader`. IALoader looks at the metadata associated with their items and uses that to build the configuration for the emulator.
 
 ## Examples ##
 
     var emulator = IALoader("#canvas", "atari_2600_pitfall_1983_cce_c-813/atari_2600_pitfall_1983_cce_c-813.bin");

+* `requestFullScreen()`
