This is the source for the Chrome extension J-Play, which creates a game oriented view of the archived content on j-archive.com. Browsing to any game on the j-archive.com website lets you toggle the game style to play along in broadcast order.
You can install the J-Play extension from the Chrome extension store, or you can use Chrome's developer mode to load an unpacked extension by browsing to the extension directory in this git checkout.
Please feel free to contribute improvements for the extension, which I will be glad to consider incorporating into my version. If you use this code to create your own published extension, be sure to mention the Copyright in the public listing.
