58  <h2><a name="dist"></a> 1.3 Distributing Enigma</h2>  <!-- ====================================================================== -->
59    <h2><a name="oxyd"></a> 1.3 Emulating Oxyd</h2>
60    
61    <p>Enigma started out in an attempt to revive the game idea behind the
62    Oxyd games published by Dongleware.  The series consisted of four
63    games: Oxyd 1, Per.Oxyd, Oxyd magnum and Oxyd extra.  Oxyd 1 and
64    Per.Oxyd were quite successful back when Ataris were cool, and the PC
65    and MAC conversions also garnered a sizeable fan community.  But,
66    calling for a modest amount of intelligence, they obviously never
67    appealed to the masses, and in 2002 Dongleware decided to withdraw
68    from the gaming business and consequently to abandon Oxyd.</p>
69    
70    <p>Now, more than one year later, Enigma is finally capable of
71    emulating much of Oxyd's core functionality.  The gaming experience
72    unfortunately isn't yet perfect: Enigma does not have some of the game
73    objects and important features like network support are utterly
74    missing.  Importing Oxyd's sound effects and <i>does</i> work however,
75    as does importing some of the original levels.  What we may never
76    achieve to copy, however, is Oxyd's overall feel: objects will always
77    move differently, accelerate differently, act a little differently.
78    Do not expect a <i>perfect</i> Oxyd clone any time soon.</p>
79    
80    <p>Enigma will automatically import all Oxyd data files it can find.
81    All you have to do is copy at least one of the following files to
82    Enigma's data directory:</p>
83    
84    <table>
85      <tr><td>Per.Oxyd </td><td><tt>peroxyd.dat</tt></tr>
86      <tr><td>Oxyd 1   </td><td><tt>oxyd1ibm.dat</tt></tr>
87      <tr><td>Oxyd extra   </td><td><tt>oxydex.dat</tt></tr>
88      <tr><td>Oxyd magnum  </td><td><tt>oxydmibm.dat</tt></tr>
89      <tr><td>Oxyd magnum gold </td><td><tt>oxydmgg.dat</tt></tr>
90    </table>
91    
92    <p>Now, where is Enigma's data directory? That depends:</p>
93    
94    <p class="osdep">
95    <b>Windows:</b> There's a <tt>data</tt> folder in Enigma's
96          installation directory, the location of which you can specify in
97          the installation program.  Usually
98          <tt>C:\Program Files\Enigma\data</tt> or something similar
99          should work.
100    </p>
101    
102    <p class="osdep">
103    <b>Unix:</b> There are two alternatives: First, if you are root,
104          you can copy the
105          <tt>.dat</tt> file to <tt>/usr/local/share/enigma</tt> or
106          <tt>/usr/share/games/enigma</tt> or wherever you (or your package
107          manager) put Enigma's data files.  Note that there is no
108          directory called
109          <tt>data</tt> on Unix.  Second, you can make a create a
110          <tt>.enigma</tt> directory in your home dir and put Oxyd's files
111          there.
