No, is not software of any cloak and dagger agency =)
It is software, source, firmware, etc.. potential for income far greater than value of l2off files... for the right person.
You are the author?
If no, my thanks for pointing these tools out!
If yes, full praise for you! I never thought anyone to create(or create and share openly, with full source no less): .u decompiler or open .xdat editor. These are really significant contributions!
Q: non-instanced content?
A:
Instanced content like Kamaloka, Seed of Infinity or Seed of Destruction is made none instanced.
Meaning it will be a normal area that any player can enter without time limits or player limits. Mobs inside will get an respawn time of what would normally be the instance lockout time.
So once it respawns people can enter to kill the boss or each other instead of every party/clan getting their very own version of it.
