The packet table
| Packet 'opcode' | Description |
|---|---|
| i | Server information |
| p | Ping |
| c | Client list |
Recieving the packets
The header of the query response will be the exact same thing that the client sent, except that the header sent by the server will always be MP04, and not VCMP. This acts as a compatibility check due to the differing protocols.
