OpenKore is a community-maintained descendant of Solos Kore, a custom client and an advanced automated assistant for the MMORPG Ragnarok Online. It's free and open-source software, application, free software licensed under GNU General Public License. OpenKore is mainly written in Perl, but some code is also in C++ XS modules. The Perl interpreter allows for a cross-platform usability and an ability to work with the source code without recompiling or even interrupting the program. OpenKore is not associated with Gravity (developers of Ragnarok Online). Developers work on the project pseudonymously, mostly due to privacy issues and internet gaming community traditions.
The OpenKore project was started by VCL in late November 2003. At the moment, there was original Kore, probably the only well-known free software Ragnarok Online bot, but due to lack of organization, many forks and modifications existed. OpenKore is based on Skore-revamped, which is a modified version of Skore (Solos Kore), which is a fork of the original Kore developed by Kura. It was started as an attempt to unite contributors to Kore forks, and that was quite successful. Gradually, other Ragnarok Online bot projects have phased out, mostly due to server-side updates and lack of development. Many developers have come from other inactive Ragnarok Online bot program projects (e.g. ApezBot, Kore, Modkore, Revemu, Skore, etc.) to develop on OpenKore.
Jet trails across an autumn sky
High tail it to your bikes and fly
If you could
Over the neighborhood
Zipped up against the evening damp
You're off and riding up the ramp
And where you land
Is different than where you planned
CHORUS
Ape hanger
We're gonna ride right off
Wrote our names on Cemetery Bridge
Threw jack-o-lanterns off the edge
Into the dark
And waited for dogs to bark
CHORUS
