My knowledge of Java is not enough to fully optimize the kernel, but I can modify an existing code to fit your needs. All of the missing moments, I make myself.
I did 90% of the missing moment, which I need for the month, but I would spend a few years, optimizing their old source code to the level of modern L2j. Sorry for my English, I am using Google Translate for posting.
English: L2jserver is very good, you should stop Hi5, Hi5 up was the best revisions, missing a lot and hopefully the l2jserver Hi5 is the best in the market, fully corrected, additions and all, in my opinion GoD up is all crap
Portugues: L2jserver é muito bom, deve parar no Hi5, até Hi5 foi as melhores revisoes, falta muita coisa e tomara que o l2jserver seja o melhor Hi5 do mercado, totalmente corrigido, adições e tudo mais, na minha opniao GoD para cima é tudo uma porcaria
