Protocol:Packet 0x60

Clients send Packet 0x60 to the server to forward a "game command" to all clients in the lobby. This is used for various things in game, including telling clients what items are dropped when a box is opened (clients "ask" the party leader what should be dropped with a form of Packet 0x62 and the party leader replies with a Subcommand 0x5F).

PSO v3 (GameCube, Xbox, Blue Burst) sometimes uses packet 0x6C, which has exactly the same format and function as 0x60.

PSO Episode 3 sometimes uses packets 0xC9 and 0xCB in games, which also behave exactly like 0x60. Sending an 0xC9 or 0xCB to a non-Episode 3 client would cause that client to disconnect.
