Packet Flags
There are various events that trigger one of these packets, and each one might have a slightly different format.
Flag 0x01 (Client->Server)
When an Episode III client leaves a team, it will send a packet with the flags value set to 0x01. I'm not totally sure exactly what each value in the packet is supposed to signify in this case. These should generate a reply from the server in the format shown next.
Flag 0x01 (Server->Client)
In reply to an 0x01 from the client, the server should generate its own 0x01 to reply back. Here's the specifics of it:
| Bytes | Meaning |
|---|---|
| 0x04-0x07 | Current Meseta |
| 0x08-0x0B | Total Meseta ever earned |
| 0x0C-0x0D | Always 0? |
| 0x0E-0x0F | Identical to the client->server packet's data in these bytes. |
Flag 0x02 (Client->Server)
When a client uses the Jukebox in the lobby, they will send this packet. Bytes 0x08-0x0B seem to always be equal to the cost of using the jukebox (0x00000064 or 100). The server should generate an 0x03 in reply.
Flag 0x03 (Server->Client)
In reply to an 0x02, the server should generate this subpacket. The format is identical to the server->client version of the 0x01 subpacket.
