In the interests of restoring to Game Play Color some of the original Game Play design that didn't make the first-cut, I've been gradually converting these elements over to pure HTML and CSS.

One piece I found particularly daunting was the rendering of the original Game Boy cartridge used in the game library. The current version of Game Play Color sports a much simpler game library for this very reason.

On the left you can see the more skeuomorphic Game Play game library; on the right, the simpler Game Play Color game library.

This has always felt like the lazy approach (and I'm not a fan of exclusively flat design) so, a few days ago, I set about rectifying the situation:

Super Mario Land
This Side Out

The HTML for this is fairly simple, though I'm disappointed by the number of elements required, especially for the embossed bars across the top of the cartridge:

<div class="cartridge">
    <div class="top"></div>
    <div class="logo"></div>
    <div class="lines">
        <div class="bar left one"></div>
        <div class="bar left two"></div>
        <div class="bar left three"></div>
        <div class="bar left four"></div>
        <div class="bar right one"></div>
        <div class="bar right two"></div>
        <div class="bar right three"></div>
        <div class="bar right four"></div>
    </div>
    <div class="inset">
        <div class="label">
            <div class="title right">Super Mario Land</div>
            <div class="title left">This Side Out</div>
            <img src="mario.jpg" />
        </div>
    </div>
    <div class="edge left"></div>
    <div class="edge right"></div>
    <div class="arrow"></div>
</div>

Unfortunately, the CSS proves a little more complex, with many special cases and absolute dimensions:

.cartridge {
    width: 140px;
    height: 152px;
    background-color: #848086;

Generally, I find the overall result fairly pleasing and, adding a few tweaks for Game Boy Color cartridges games helps keep things playful:
