The server sends Packets 0x07 and 0xA0 to communicate either a ship or block list to the client. The Sylverant Login Server always sends Packet 0x07 for the purpose of communicating the ship list, but the Ship Server uses 0xA0 for this purpose. This seems to be how other PSO servers implement the functionality, so I went for uniformity (either packet will probably work in either situation). Block lists (only communicated by the Ship Server) always use type 0x07.
The lobby list sent to clients by the ship server is sent as Packet 0x1F, and follows this same format.
The clients send Packet type 0xA0 to request the ship list when already on a ship. The server will then respond with a Packet 0xA0 generally (as mentioned above).
