<p>
<h2><b>DOS</b></h2>
<p>The DOS version of Stella is distributed as a ZIP archive containing the DOS
executable as well as some other files. The DOS version of Stella
works with DOS as well as Windows 9x. The DOS version will run under
Windows NT, 2000, and XP, however, the sound may not operate correctly.
You should install it as follows:</p>
<ol>
<li>Change directories to the root directory:<br>
<pre> CD C:\</pre></li>
<li>Extract the Stella distribution:
<pre> unzip st<i>release</i>.zip</pre></li>
<li>Add the following to your <b>AUTOEXEC.BAT</b> file:
<pre> SET PATH=%PATH%;C:\STELLA</pre></li>
<li>If you have a Sound Blaster or 100% compatible sound card make sure
the <b>BLASTER</b> environment variable is set in your <b>AUTOEXEC.BAT</b> file.
The sound driver will attempt to auto-detect your card if the <b>BLASTER</b> variable
isn't correctly specified.
For example:
<pre> SET BLASTER=A220 I7 D1</pre></li>
<li>If you have a mouse make sure your mouse driver is loaded in either the
<b>CONFIG.SYS</b> file or the <b>AUTOEXEC.BAT</b> file</li>
<li>Reboot your system</li>
</ol>
<p>For the second step you'll need a program for extracting ZIP archive files.
You can use PKUNZIP for DOS, the Info-Zip UnZip tool for DOS, or a number of
other programs available for extracting ZIP files.</p>
<p>
<h2><b>Linux</b></h2>
<h2><b>Linux/UNIX</b></h2>
<p>The Linux versions of Stella are distributed in both executable and source code
form, and in compressed tar files as well as (S)RPM's.
<p>If you're using the executables from a compressed tar file, follow these instructions:
<ul>
<li>Extract files from the distribution:
<pre> tar -jxvf stella-<i>release</i>-linux-<i>arch</i>.tar.bz2</pre></li>
<li>Login as root and change directories to the distribution directory</li>
<li>Copy the executable to a directory that's in your path:
<pre> cp stella.sdl /usr/local/bin</pre></li>
<li>Copy the supplied stella.pro properties file to the system-wide location:
<pre> cp stella.pro /etc</pre> or to your home directory:
<pre> mkdir ~/.stella<br> cp stella.pro ~/.stella</pre></li>
</ul>
<p>If you're compiling the source from a compressed tar file, follow these instructions:
<ul>
<li>Extract files from the distribution:

<li>Change directories to the stella-<i>release</i>/src/build directory</li>
<li>Edit the <b>makefile</b> to meet your needs</li>
<li>Build the executable with the following command:

<p><b>Emulator Game Shells</b></p>
<p>Instead of using the command line to run Stella you may find it easier to
use an emulator game shell. An emulator game shell allows you to pick games
from a menu without having to type everything at the command line. One such
game shell is Jim Pragit's "Game Menu". Other frontends can be found at the

<a name="Adaptor">8. Real Paddle Adaptor</a></h1>
<a name="Adaptor">8. Stelladaptor Support</a></h1>
<hr>
<p>The DOS and Linux versions of Stella support real Atari 2600 paddles using
a special adaptor which connects to the PC game port. The adaptor requires the
following parts:</p>
<p>Stella supports real Atari 2600 joysticks and paddles using the
<a href="http://www.pixelspast.com/products">Stelladaptor</a> device.
The 1.4 release of Stella does not yet support driving controllers connected
to a Stelladaptor.</p>
<p>Stella can use up to <b>two</b> Stelladaptors; any extra ones are ignored.
Stelladaptor devices will be automatically detected and configured. The
detection and configuration is as follows:
<ul>
<li>1 DB15 male connector (joystick extension cable plugs into this)</li>
<li>2 DB9 male connectors (paddles plug into these)</li>
<li>4 115k resistors</li>
<li>1 Small project box</li>
<li>1 Joystick extension cable</li>
<li>Some wire or ribbon cable</li>
<li>The first Stelladaptor found will act as either the left physical
joystick or paddles 1 & 2. Basically, whatever controller you plug
into it will behave as if it were plugged in to the <b>left game
port</b> on a real Atari.</li>
<li>The second Stelladaptor found will act as either the right physical
joystick or paddles 3 & 4. Basically, whatever controller you plug
into it will behave as if it were plugged in to the <b>right game
port</b> on a real Atari.</li>
<li>Any other Stelladaptors will be ignored.</li>
</ul>
<p>Most of these parts can be found at Radio Shack. I could not find a DB15
connector there or the 115k resistors, however, if you're willing to sacrifice
a joystick extension cable you can do without the DB15 connector and you can
always place a 100k resistor and 15k resistor in series to make a 115k
resistor. A schematic of the adaptor is shown below:</p>
<p><a><img src="graphics/circuit.png"></a></p>
<p>As you build the adaptor be careful not to short the +5V and GND
connections. Although several people have built this adaptor and use it
no guarantee is given that the circuit is error free therefore
<b>USE IT AT YOUR OWN RISK!</b></p>
