<h2 id="whatsthis">What's this?</h2>
<p>
Play! is a PlayStation 2 console emulator still in preliminary stages. This won't run your favorite
PlayStation 2 game perfectly at optimal speed: this only works with a few demos and games created by
people involved in the non-professional PS2 coding scene.

<h2 id="guide">Basic User Guide</h2>
<h3 id="home_directory">Home Directory</h3>
<p>
The first time you'll be running the emulator, it'll create a new "Play Data Files" folder in your "My Documents" folder.
This is going to be the place where the emulator will store saved games and also the place where it will look for homebrewn games data files.
</p>
<h3 id="guide_playing">Playing a Game</h3>
<p>
To play an homebrewn game or demo, follow these steps:
</p>
<ul>
<li>Extract the contents of the archive containing the game or demo data into the "/vfs/host" subdirectory of the home directory.</li>
<li>In the emulator, select "File | Load ELF..." from the menu bar.</li>
<li>Select the ELF executable image file that should have been extracted in the "/vfs/host" directory.</li>
<li>After a successful loading, the virtual machine will start executing the program.</li>
</ul>
<p>
To play a commercial game on a DVD-ROM or in a disk image in raw ISO9660 format (.iso file), follow these steps:
</p>
<ul>
<li>
Configure the source that will be used for the disk data by selecting "Options | Virtual File System Manager..." from the menu bar
and double clicking on the "cdrom0" device.
<ul>
<li>
If you want to use a physical DVD-ROM, click the "Physical CD/DVD Reader Device" radio button
and select the drive that'll be containing the disk in the combo box below.
</li>
<li>
If you have a disk image, click the "ISO9660 Disk Image" radio button and select your image file by clicking the "..." button.
</li>
<li>
Confirm your changes and go back to the main window.
</li>
</ul>
</li>
<li>Select "File | Boot cdrom0" from the menu bar.</li>
<li>After a successful loading, the virtual machine will start executing the program.</li>
<li>Note: You can also use the "File | Boot Disk Image..." to load a disk image file directly.</li>
</ul>
<h3 id="guide_controls">Game Controls</h3>
<p>
You can change your controller configuration by selecting "Options | Controller Settings...". It's possible to use either your keyboard
or your DirectInput compatible game controller to bind with the Dual Shock controller keys. The default config is this one:
</p>
<table class="ctrl">
<tr>
<td class="ctrl_header">Dual Shock Controller Button</td>
<td class="ctrl_header">Keyboard Equivalent</td>
</tr>
<tr>
<td>Left (d-pad)</td>
<td>Left Arrow</td>
</tr>
<tr>
<td>Right (d-pad)</td>
<td>Right Arrow</td>
</tr>
<tr>
<td>Up (d-pad)</td>

<tr>

<tr>
<td>Select</td>
<td>Left or Right Shift</td>
</tr>
</table>
<h3 id="guide_state">State Saving/Loading</h3>
<p>
To save a state, simply press F7 or select the "Virtual Machine | Save State" menu item.
To load a previously saved state, press F8 or select the "Virtual Machine | Load State" menu item. There's also 10 slots
available for you to place your saved states in, accessible through the "Virtual Machine | State Slot" submenu. Please note that
saved states aren't very stable and could result in data loss. Prefer using the game's save mechanism if it's available.
</p>
</div>

<div>
<h2 id="ext">OpenGL Extensions</h2>
<p>
The current GS handler requires some OpenGL extensions in order to emulate some features of the GS correctly.
To check which extensions are supported by your video card driver, consult the "Renderer Settings" dialog in the emulator.
The following table lists which extensions are currently being used and what might be the consequences
if your video card driver do not support them.
</p>
<table class="ext">
<tr>
<td class="comp_header">Extension</td>
<td class="comp_header">Absence Effect</td>
</tr>
<tr>

<td>Used for "Ys I & II: Eternal Story". Some elements of the game that should appear translucent will appear opaque.</td>
