    • Faltan demasiados archivos,  y lógicas en clases claves como L2pcInstance, entre otras. si bien muchas cosas están y el flujo es valorable.  Gracias por tu esfuerzo es bastante... pero realmente no esta completo el código, falta que subas todas las modificaciones en clases colaterales... podrías intentar subir un diff de todo el mod  completo de tu pack y bueno ahí si que cada uno adapte... pero faltan muchas cosas, dudo que haya gente que lo haya echo funcionar con esto... 
    • I know people who have fully bypassed and reversed AAC. One day, they might even release the full source code, but for now, they’re still making money off it. I won’t name anyone, but it’s clear that there aren’t any truly solid anticheats for Lineage2. As I’ve said before, kernel level anticheats are the only real solution. Anything that runs as Internal and injects gets flagged, and your account ends up getting kicked or banned. That’s just how most games handle it nowadays. To TL;DR the whole thing cheating will always exist because there are people out there smart enough to bypass any protection and run private cheats. Public cheats are always detected eventually, so I don’t see any point in buying AAC, especially when they claim it blocks adr, which simply isn’t true.
