An example of editing SHIPDAT0.Z66 from Zone66, each ship follows a similar pattern. as follows:

------------------------------------------------------------------------------------------
File=
Name=
Payload=??
FuelComp=??
Armor=??
TopSpeed=??
Acceleration=?? (00 Excellent, 01 Good, 02 Fair, 03 Bad, 04 Terrible)
Turning=?? (Use above)
------------------------------------------------------------------------------------------

Also before each ship name is a couple of bytes that tell which ship graphic is used and where it is. I will provide a list later when I have more time. After Turning is some unknown bytes then there are the weapon info. As you can see, DFA. BOMBER has 4 weapons spaced by some unknown bytes. The weapon input is like this so far I have found:

------------------------------------------------------------------------------------------
WeaponType=?? (00 Machine Gun, 01 Lazer, 02 Phazer, 03 Particle Gun, 04=Anti-Air Missile [used by turrets], and 05 Ship Air-to-Ait Missile)
WeaponAngle=?? (00 seems to be straight ahead, 0F is off like \,
the rest is pretty easy to figure out)
------------------------------------------------------------------------------------------

Additionally before all this data (F9) tells the length of the datafile so it is best left alone, apparently it has to do with the compression used by ZONE 66. I am hopeing that the compression may be cracked someday. Until then this is all I have.
