&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;0052.lzh&amp;#039;&amp;#039;&amp;#039; (Also referred to generally as エミュ鯖 or &amp;quot;Emu Saba&amp;quot;/ &amp;quot;Emu Server&amp;quot;) is the predecessor for the server emulators [[Athena (Server Emulator)]], [[Weiss (Server Emulator)]] and [[YARE (Server Emulator)|YARE]], originally published on 19 January 2003. The name refers to a lzh archive file which was shared on the &amp;quot;EmuServer Of Ragnarok&amp;quot;, which is one of the origins of code utilising the Ragnarok Online packets, which in 2003 were unencrypted.&lt;br /&gt;
&lt;br /&gt;
=== Background ===&lt;br /&gt;
On the &amp;quot;[[EmuServer Of Ragnarok (EOR)|EmuServer of Ragnarok]]&amp;quot; BBS, several authors who were previously players of the Ragnarok Online Beta in 2001, which created a BBS to discuss the emulation of Ragnarok Online and how that would be accomplished at some point in October 2002 . Those who had been able to perform packet sniffing had looked into how the beta from 2001 functioned and had stored the contents of the packets -- this was then then used as the basis of fragments of code to try and reproduce these packets, which were posted by various authors -- one author in particular, Mr 35 (an automatically generated ID for the given BBS) uploaded files with various numbers, 0052 being a fairly well-fleshed-out predecessor known as I-Athena, which is the predecessor to the Athena Emulator.&lt;br /&gt;
&lt;br /&gt;
In February of 2003, a user by the name of &amp;quot;i2&amp;quot;  posted his intention to develop Athena: &lt;br /&gt;
 462 Name: i2 ★ Post date: 2003/03/18 (Tue) 23:31 ID:MBcWy.lI&lt;br /&gt;
 I discovered the topic of emu mackerel at the end of February, and thought it would be a good learning material for programming, so I decided to develop it with a friend.&lt;br /&gt;
 We have improved the source of the C language-based &amp;quot;Athena&amp;quot; and will release it as &amp;quot;I-Athena&amp;quot;.&lt;br /&gt;
 I&amp;#039;m a newbie, but I appreciate your continued support.&lt;br /&gt;
