Protocol:Packet 0x07

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.

Dreamcast Packet Format

Bytes	Meaning
0x00	Packet Type (0x07 or 0xA0)
0x01	Flags (Number of Entries)
0x02-0x03	Packet Size (Variable)
0x04...	Ship/Block Information (see below for format)

The ship information field is populated as follows (offsets are relative):

Bytes	Meaning
0x00-0x03	Menu ID (0x00000005 on Sylverant)
0x04-0x07	Item ID (The item in the list)
0x08-0x09	Flags (0x0004 for the phantom ship entry, 0x0000 for all others)
0x0A-0x1B	Ship/Block Name

In addition, for a ship select there is always a phantom ship in front of the list that is populated as follows:

Menu ID	0x00000005
Item ID	0x00000000
Flags	0x0004 (make invisible?)
Ship/Block Name	"DATABASE/JP" (and set the last byte of the field to 0x08)

For a block select, the phantom entry is as follows:

Menu ID	0x00000001
Item ID	0x00000000
Flags	0x0000
Ship/Block Name	The name of the Ship (with the second to last byte set to 0x08)
