vL//vL was game, iced-cream was character, and account was Kcoj14@useast
can anyone make heads or tails of this? I'm not sure if 0x1C is used to create games for ALL clients, and if the values are the same. By the looks of it, making D2 games is much different, if I assume correctly.
Yes, I'm sure many people can make heads and/or tails of it, as it's pretty simple stuff. Do you have a specific question? =P

0x22 Tells BNCS you joined a game
0x03 and 0x04 are they UDP or something? i dont recognize the packet format
He said 'realm server' =P

Like SoulTaker said, I did say realm server - which is TCP
Diablo II/Lord of Destruction and Warcraft III/The Frozen Throne are the only Battle.net games that do not use UDP for gaming, it's all TCP.
So 0x03//0x04 would be sent on a seperate TCP socket, one used for realm stuff?

The same socket you used for logging onto your character, which would be the one you're using for the realm
can i get some help on how 2 read the packet?

Both
One way you can figure it out is by packet logging it multiple times with different characters, different game names and see what changes and what doesn't
Edit: Fixed quote
It would help a great deal if you posted your source code as well as the packet logs, so that it is easier to see where something went wrong.

He doesn't know how to read the packet, he most likely doesn't have much if any useful code to show. Packetlogs > *

D2GS packets are always in the following format:
(BYTE) Packet ID
(VOID) Packet Data
However these packets are compressed using what appears to be a broken Huffman encryption.
MCP (Realm) packets are always in the following format:
(WORD) Packet length, including this header
(BYTE) Packet ID
(VOID) Packet Data
So, help me read 0x03, 0x04, and 0x1C?
