Hello Mxc forum,

 

In my attempt to correct l2jattackers and other packet flooding sh***s i tried to rework the mmocore, i didn't find the way so i made a code for packethandler debug,

Anyway here we are:

      WIP Free Assasins Interface for Interlude

      By Nefalem · Posted

      I didn't even want to touch on your name Celestine, but it took a while to want to protect it, right? But then I say, everyone knows that you and your group helped Vraekar in deobfuscating the interfaces, do you want me to post here the dates and videos of the releases of the OMG and Silence interfaces?, and then see Vraekar's?, do you want?, a blatant copy, even their variable names, the theft is blatant, and you who are an admin here at Max and say you are the right one, helped him decrypt and remove the code obfuscation, everyone knows that, and now you come and tell me that his code is not copied?, if you want I can put all the evidence here and this will be very ugly even for you, since those you helped Vraekar and the interface dev community know this, they know about the thefts, very ugly indeed my friend that you still come and tell such a lie.   ps. And just one more thing, did you say that all the code he wrote? you became a joker? Vraekar doesn't program a single line of code, the guy works as a data analyst, what he learned was to copy and paste ready-made codes, but he doesn't write a single line of code.

      aCis - another CRAPPY interlude server

      By mend3 · Posted

      I'd like to join aCis community but i can't handle the contributions that often due to my job. I'm returning to L2 development after a few years away and it would be awesome getting this source to work. I can (and would like to) contribute with reviews and code now and then (i'm software engineer for global companies), but sadly i can't commit the time.   I have a hard sense of ethical to not not leak anything (my current web project is paid from nkdev even when there's a leaked version floating around.)   Please let me know when/if acceptance through donations is available again. @Tryskell   In the mean time, gl on your project. Sounds amazing.

      I don't understand why you're judging Vraekar at all. He did nothing wrong. I've checked the code from that interface, and all the code inside the UC was written by Vraekar. Nothing was copy-pasted. It's the people who stole this patch and are reselling it at a higher price so who's the scammer here, Vraekar or them?
