The server is essentially expected to pad the packets in that case.

BlueCrab: Add page showing all packet header types

Add page showing all packet header types

New page

Different versions of PSO use slightly different formats for the headers on all packets sent to and from the server. PSO versions up to, and including, PSOGC use a 4-byte header, while PSO Blue Burst uses an 8-byte header. All packets must be some multiple of their header in size.
