This is a file of hex values relating to the vehicles of Phantasy Star IV.
There are a lot of values relevant to each, and this does not include the
"optin" attacks that they use. Those are in another well-named file.

Part 1) Byte descriptions [part1]
Part 2) Byte list [part2]
Part 3) Notes [part3]


Part 1) Byte descriptions [part1]

!1: This is the name of the vehicle as it is commonly known. Technically,
  besides the game's full text and as an item, this is never used, so it does
  not seem to be located elsewhere.

!2: This is not part of the information here. This is the offset at which this
  data can be found.

Byte 1: HP, high byte. Multiply this by 256 and add the next byte for HP.
Byte 2: HP, low byte.

Byte 3: Strength
Byte 4: Mental
Byte 5: Agility
Byte 6: Dexterity
Byte 7: Attack
Byte 8: Defense
Byte 9: Magic defense

Byte 10: Physical properties
  00: immune
  01: resistant
  02: normal
  03: weak

Byte 11: Energy properties, similar
Byte 12: Fire properties
Byte 13: Gravity properties
Byte 14: Water properties
Byte 15: Anti-Evil properties
Byte 16: Electric properties
Byte 17: Holyword properties
Byte 18: Brose properties
Byte 19: Biological properties
Byte 20: Psychic properties
Byte 21: Mechanical properties
Byte 22: Efess properties
Byte 23: Destroy properties

Byte 24: This byte (as I theorized earlier) shows which Optin abilities are
  available to the vehicle. More experimentation is needed to show whether more
  than two can be used, but it seems possible to put ALL of them on by entering
  FF.
  +1 Cluster
  +2 Gravitn
  +4 Th.Grid
  +8 X-Burst
  +10 Napalm
  +20 Nothing (same stats as Cluster)
  +40 N-Spher
  +80 Nothing (same stats as Cluster)
  Unfortunately I've had trouble changing the vehicles' abilities. More tests
  are needed.

Byte 25: Available uses of the first Optin
Byte 26: Available uses of the second Optin


Part 2) Byte list [part1]

Part 3) Notes [part3]

-Byte 24 is really interesting. I'll see if it's possible to use more than two
  optins sometime soon. It would be cake to test; for example, set byte 24 to
  -1A for Napalm, Gravitn and X-Burst
  -70 for Napalm, N-Spher and the first Nothing
  -7 for Cluster, Gravitn and Th.Grid
  -FF for ALL optins

  If you don't want to be greedy but simply have some favorite abilities, you
  can just add two, keeping in mind that it's hex.
  -14 for Th.Grid and Napalm is a good choice, then.
  I've tried changing this value and had issues. Perhaps this is stored
  somewhere else as well? This is definitely the meaning of this byte.

-All of the optins use the vehicles' strength. The hydrofoil has low attack
  power, but an impressive (ie. maxed) strength stat. Try using Cluster with
  the hydrofoil! You might be impressed.

-Then again, if you were going to hack the vehicles anyways, you might as well
  give the other ones a strength boost. Duh.
