<h2>System Requirements</h2>
-<p><i>Virtual Jaguar</i> should be able to run on most late model computers equipped with an OpenGL compliant video card. It requires a lot of raw <i>oomph</i> in it’s present form to run well; do not be surprised if it doesn’t run at 100% speed with all the options, such as sound and DSP, turned on. Certain subsystems of the Jaguar are not optimized yet and as such take more time than they would if they were optimized. To run <i>Virtual Jaguar</i> at full speed with all options on, we recommend using liquid nitrogen. At least until we get it properly optimized. ;-)</p>

<h2><i>Virtual Jaguar</i> In Depth</h2>
<li>Enable Jaguar BIOS</li>
<li>Enable GPU</li>
<li>Enable DSP</li>
-<li>Enable audio playback</li>
<li>Show all files in file chooser</li>
</ul>
<h3>Enable DSP</h3>
-<p>The DSP is one of the three main processors in the Jaguar, and checking this option enables it. Much software will work without it, however, there is some software that will not.</p>
-
-<h3>Enable audio playback</h3>
-
-<p>Checking this option will allow <i>Virtual Jaguar</i> to attempt to output sound to your sound card. It will <b>not</b> output <b>any</b> sound without the DSP being enabled.</p>
