<h2 id="whatsthis">What's this?</h2>
<p>
Purei! (written in Japanese kana as well) is a PlayStation 2 console emulator still in
preliminary stages. This won't run your favorite PlayStation 2 game perfectly and with
the optimal speed: this only works with a few number of demos and games created by people
involved in the non-professional PS2 coding scene.
</p>
</div>
<hr />
<div>
<h2 id="requirements">System Requirements</h2>
<p>
A PC running Windows 2000/XP/2003 and a CPU supporting SSE should be enough to be able to run the emulator.
</p>
<p>
For interesting emulation speeds, a CPU clocked at at least 1GHz is required.
</p>
<p>
The emulator isn't really greedy memory wise, as 256MBs of RAM should be enough to prevent
any hardcore virtual memory page swapping.
</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 executable into the "/vfs/host" subdirectory present in the Purei! directory.</li>
<li>Select "File | Load ELF..." from the menu bar.</li>
<li>Select the ELF executable image file you've previously extracted.</li>
<li>After a successful loading, the virtual machine will start executing the program.</li>
</ul>
<p>
To play a commercial game present on a DVD-ROM or in a disk image in raw ISO9660 format, follow these steps:
</p>
<ul>
<li>
Configure the source that will be used to read the disk from by selecting "Options | Virtual File System Manager..." from the menu bar
and double clicking on the "cdrom0" device.
<ul>
<li>
If you have a physical disk you'll be reading from your DVD-ROM drive, 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>
</ul>
<h3 id="guide_controls">Game Controls</h3>
<p>
This is the current controller to keyboard button mapping configuration which is hardcoded in the
program for the moment. It will be possible to change them in a later version.
</p>
<table class="ctrl">
<tr>
<td class="ctrl_header">Dual Shock Controller Button</td>
<td class="ctrl_header">Keyboard Equivalent</td>

<h3 id="guide_state">State Saving/Loading</h3>
<p>
Since memory card support isn't there yet, you might find it more convenient to save your
games using saved states. 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.
</p>

<div>
<h2 id="ext">OpenGL Extensions</h2>
<p>
The current GS handler requires some OpenGL extensions to be allowed to render
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>
<td>glBlendColor function</td>
<td>Used for "Ys I & II: Eternal Story". Some elements of the game that should appear translucent will appear opaque.</td>

I'm not looking forward bug reports for now since I know it's buggy. And I'm not looking for source code patches to fix bugs either. Anything else should be fine though.
