eAthena, short for English Athena, is a cross-platform, open-source game server software for the popular MMORPG Ragnarok Online.[1] It is an emulation of the Aegis software created by Gravity Co., Ltd. that powers the official Ragnarok Online servers, and is used to run private servers.[1] This is accomplished through modifying the game client provided by Gravity to connect to private, instead of official servers.[1]
History
Athena (commonly called jAthena, short for Japanese Athena, by non-Japanese speakers) was a Ragnarok Online game server emulation project that was started in late 2002.[1] It was created because around this time, the official free-to-play Ragnarok Online servers exited the open-beta phase and became pay-to-play, and many players either did not want to or could not pay to play the game.
In late 2003, Applemod was created out of the original jAthena project by a developer that went by the handle AppleGirl, mainly as an English translation for jAthena with several other modifications. Another developer that went by the handle Akaru then modified AppleMod to create AkaruMod, with further changes. In early 2004, AppleGirl, Akaru and another developer by the name RoVeRT decided to merge using the AppleMod base and found what is known today as eAthena, as an actual fork of jAthena that would be collectively maintained. It has been under active development ever since. You can see one part of the eAthena timeline at end of the page. [2]
Specifications
eAthena is coded in the C programming language and makes use of the zlib and MySQL libraries. The actual application is split into three servers - login, char, and map, each of which serve a different purpose. Support for multiple map servers is also possible. Thus, while the individual eAthena servers are single-threaded, they do essentially have support for running on multiple processes, and even on multiple computers.
For storage of dynamic game data, eAthena can be compiled to use one of two different modes of database operation: TXT or SQL. TXT is short for plain-text whereas SQL is MySQL. SQL is the standard way of running the eAthena servers. TXT is generally used merely only for testing and development purposes as a quick and convenient way to get eAthena up and running without having to deal with any 3rd-party software, and is not recommended for live, production servers.
eAthena uses plain-text databases for configuration of static game data such as item, monster, and skill information, although some of these can optionally be configured to use MySQL instead. Additionally, eAthena features a fully custom, C-like scripting engine for configuration of NPCs, quests, warp portals, and monster spawns, among other interactive in-game systems.
There have been talks of and attempts at improving the eAthena code base for years, including full-scale conversion to C++ (called eAPP), replacement of the TXT system with SQLite, and replacement of the script engine with Lua, but none of these ideas have ever been completed.
Comparison with Aegis
eAthena has proven to be a solid, up-to-date, and very close emulation of Gravity's own Aegis software. This has been accomplished by analysis of both Gravity's Ragnarok Online client software and from Aegis itself, which has been leaked numerous times.[1] Most of eAthena's databases and scripts have in fact been converted directly from leaked Aegis packages.[1] eAthena's progress usually lags behind Aegis' an episode or so, as updated leaks are required to obtain new data.
eAthena is efficient, stable, and secure. Both Aegis and eAthena can handle thousands of players at once without issues, and security exploits that are discovered are quickly patched. However, eAthena interestingly has a number of notable advantages over Aegis, of which include the following:
- eAthena is cross-platform and can run on both Microsoft Windows and Unix-like platforms (such as Linux and Mac OS X), while Aegis is Windows-only.
- It supports the free MySQL database software as well as plain-text databases while Aegis requires the proprietary Microsoft SQL Server software.
- It is fully open-source thus allowing trivial custom modification, whereas only Aegis binaries and not source code have been leaked, making modifications limited and very difficult.
- eAthena is much easier to configure and setup than Aegis. Arguably, eAthena's databases and script engine are also easier to work with, more well-formatted, and better featured than those of Aegis.
- eAthena has many more features than Aegis and offers much greater customization. Examples include eAthena's far more robust in-game @command system versus Aegis' /command system and eAthena's powerful configuration system which allows alteration of many game functionalities without having to touch the source code, of which Aegis is nearly completely lacking, among others.
- eAthena requires far fewer resources than Aegis, namely in the area of memory. Aegis requires over 2 gb of RAM just to launch while eAthena can run on only several hundred megabytes, or even less than 100 mb using optional dynamic data allocation.
- The number of 3rd-party software available for eAthena far exceeds those of Aegis.
On the other hand, on account of Aegis being a professionally developed software, it is likely to have greater stability and security than eAthena. Additionally, Aegis is Ragnarok Online exactly how it is and was intended to be, and while eAthena strives to be as close to accurate an emulation as possible, it is not perfect, and the game mechanics are slightly different in many areas.
As of 2010, there are approximately 500 private servers running eAthena, while there are around 30 official servers running Aegis.[1] Despite Aegis being frequently leaked and available for use, it is rarely used to run private servers, primarily due to the various advantages of eAthena over it listed above.
Legality
The distribution and running of private game servers such as eAthena is disputed in some countries due to copyright and intellectual property laws.
When private servers for Ragnarok Online client first appeared in 2003, Gravity took action. A prominent example of this is when they threatened the YARE (Yet Another Ragnarok Emulator) project, at that time the emulator with the largest user base, with a lawsuit if they did not shutdown by the end of the year. However, as soon as they did, other emulator projects such as eAthena immediately took its place. Gravity has since not taken action against private server servers.
Timeline
eAthena History Guide -Evera Starting out in 2003, eAthena became one of the greater Ragnarok Online Server Emulators. While the older dates are unknown, the majority of eAthena is well documented. I initially included changes in developers, but it was hard to get information on. I included omniAthena because they too, are a part of eAthena history. <------------- Release numbers note ------------> -The original AppleMod/eAthena numbers were - -based on the Athena revision on which the mod - -was based on. - <-----------------------------------------------> November 18, 2003 - AppleMod 554a released.

Aug 4, 2004 - eAthena 1.0 RC3 released. <-- Couldn't find RC4 Release date - RC4 was crap anyway, imho --> Oct 14, 2004 - omniAthena/eAthena merge. <---------- omniAthena/eAthena merge -----------> -Ultimately, omniAthena merged into eAthena. - -Why? eAthena development picked up, as they had- -to compete against omniAthena, who were - -re-developing the same aspects as eAthena, so - -they decided to merge back together, and become- -a stronger entity in the 'Emulator Wars'. - <-----------------------------------------------> Oct 15, 2004 - eAthena 1.0 RC5 released. <------------- End of Emulator Wars ------------> -After eAthena RC5, you wouldn't see very many - -Peope using servers besides Aegis or eAthena. - -RC5 proved to be extremely stable, and was the - -standard of the time. YARE died out almost a - -year ago, WEISS was not heard of, Vidar was - -the same story as WEISS, but there were still - -some other RO emulator projects going on. - -Hostilities were gone though, until Freya - -branched off eAthena. - <-----------------------------------------------> Dec 7, 2004 - SVN Open to public <------------------ Public SVN -----------------> -When the SVN was opened to public, it meant - -that no more releases were to be issued in the - -old style. Now that we had more than enough - -developers to hold our own, we were no longer - -following jAthena, but having our own develop- - -ment. - <-----------------------------------------------> Nov 18, 2005 - eAthena Preview Release v1.0 (PR1) released. Extracted from SVN 4021 (Thanks Haplo) Period of peace. <--------------- Period of peace ---------------> -Now we enter the period of peace, a name given - -to our current age. I named it myself, but most- -users won't know the difference in time, so - -this name is meaningless to them. To the older - -members, you know what I'm talking about. No - -longer is eAthena struggling to roll out - -releases. No longer is eAthena a small group - -of a 40-person IRC channel. eAthena is now big,- -and during this period, many advancements were - -made in other fields from eAthena members. To - -name a few, Sereon, and eAOS. - -Also, during this time, the eAthena population - -boomed. Now we are a huge, bustling community. - <----------------------------------------------->
