SO I play on a server named l2revolt gracia part2 the phx works to connect if i send the original script for weapons it buy but i can"t modified the value well I can but after that it not working
example
original script taken from sniffer
6B 31 57 05 00 01 00 00 00 E1 09 00 00 01 00 00 00
so until yet i have download and read all the how to videos and read all the tutorial but is still not working, so if someone could make me a mini tutorial and explain exactly the method or what should I modified
what I understand is that at this code
6B 31 57 05 00 01 00 00 00 E1 09 00 00 01 00 00 00
the 6th and the 7th number must be modified so i start the calculator selected hex
