A JavaScript Gameboy Emulator, Detailed In 8 Parts

Posted by timothy on from the behind-the-scenes dept.

Two9A writes "JavaScript has shed its image of being a limited language, tied to DOM manipulation in a browser; in recent years, new engines and frameworks have given JS a reputation as a language capable of bigger things. Mix this in with the new elements of HTML5, and you have the capacity to emulate a game console or other system, with full graphical output. This series of articles looks in detail at how an emulator is written in JavaScript, using the example of the Gameboy handheld: starting at the CPU, and (as of part 8) running a copy of Tetris."

    I've said it before, and I'll say it again:

    You can write damn near anything in JavaScript if you really want to, but the better question is if you should.

    And yes, that includes half (but only half!) of the stuff you'll find done in JavaScript in web apps.

  2. Ode to JavaScript by CobaltBlueDW · · Score: 4, Insightful

    JavaScript is truly a horrifyingly discussing,
    intrinsically retched,
    soul darkening, succubus from the abysmal depths of conceivable depravity.

    To know its stench
    is to know the crippling limitations of our future.
    To recognize its sloven decadence
    and remain indifferent
    is to burn the righteous.

    No faith,
    however moving and spectacular,
    could light a path of its continuation.
    No argument,
    however complex and equivocated,
    could elevate such a encumbering and wearisome burden.

    There is no failure so inadequate,
    or stagnation so bereft of utility
    as that of JavaScript.

    Thankyou.
