it's humordwarfs, with his open authserver in C#.
I didnt get a chance to check it in IDA - but obviously contains abnormals, herbs and other things.
It seems to build on the xml principle he tried creating way back on PP.
Where you could use the xml format to write memory, to change stuff like clan limits and so on.
Will check it later in IDA.
DB Scripts are C4, and the ones that leaked with the original LEAK,no the cleaned up sql scripts you see with all packs now from L2Storm.
Seems to be no new Skill effects, which means its very limited.
No information about any systems.
The NPC ID limit and ammount limit seems not done.
Looking at his script6 he seems to fake switch it, probably on sendnpcinfo.
Which is kinda a "cheap" fix - but this was done early on when not many people knew much about l2server.
On top of that config file seems to do small fixes like malort reports, call reports nopping - and annoying red "warning" messages that are usually not errors.
Sell limits, item drop cleaner and other weird things based on their description.
It seems even more basic than Ezme's interlude ext that came out first.
But only one way to clearly tell :)
