Hello ! First of all thank you for answers, To answer at Solumn first, I'm not very good in programming so i checked on the Net and tried to modify them with "Cavaj" but i think i should decompile them first no ? And to answer at Tryskell, What do you mean by "Regular sources" ? My L2j Pack is old since they closed their website, i think its a 2009 pack so .. ( I saw you're french too, and i don't know if i can speak in french in the forum directly, so i ask you if i could speak with you by pm and if you could explain me ? If you got time off course ^^ Would be fantastic :) ) Once again, thank you
