Winsock Packet Editor - Trouble

Try packet filtering instead, I noticed in WoW that if I resent a packet it would kick me instantly, and I found out that was because the first four bytes of their packets are random opcodes that change every time, so sending the same one twice will never work. What I did though was filter certain parts of packets, like for example, if you're trying to sell the pearl you could record selling a pearl a few times then record selling a different item and see what byte changed. Hopefully you can find just one that changes, and that would probably be the item id. So if you add a filter at that byte offset you could make it so when you sell a pearl in game, instead it would sell something else.

That's what I did with wow, never found much except a server crash (would make everyone in an area get kicked for a minute and see "World server is down." error until the server restarted). That somehow got fixed within two weeks, I only used it two times and my friend used it about six times.

Not sure if the game you're playing has any anticheat shit, wow kinda does (warden) but you can have ce and wpe opened after launching wow and mess around all you want. Never got banned for that. But you probably can't resend packets for the same reason or a similar one.
