This is about a collection of about 300 Apple II games playable in the the browser, but the best part comes at the end of the article:

    4am meticulously and [sic] carefully walks through 
    the entire process of cracking each program. The

    solved mystery. 
    They’re magical. And every 4AM item has one.
