This is the structure from the paradise header file.  There are several (8)
subtypes of game parameter packets, subtype 0 is the one that sets sizes like
maxplayers.  Some of the fields aren't relevant to to the bronco server
(thingies), while the galaxy width and flags are even ignored by the paradise
client.  I think the nranks refers to paradise ranks and doesn't effect bronco
ranks.  I'm not sure when exactly it is sent to the client, ie before login,
after login, etc.
