Tech Control Header[edit]

Control headers set the basic properties of how a tech performs. They are 11 bytes long, and vary slightly in function depending the type of tech.

Byte 1: Varies depending on tech type.
	Player Attack or Tech: Determines Performance Group. Bit 0x80 is unused.
	Enemy Tech: Unused.
	Enemy Attack: Bits 8-0x80 are unknown flags, with 8-0x20 and 0x80 being possibly unused. 
                      Bits 1-4 form an unknown value.
Byte 2: Unknown. Testing appeared to have in impact on damage.
	Player Techs and Attacks:
		Bits 1-4: Unknown.
		Bit 8: Unused.
		Bit 0x10: Unused.
		Bit 0x20: Don't compare bits of byte 11 with enemy data 0x14. Applies to entire tech, 
                          not just a specific effect header.
		Bit 0x40: Ignore Hit and evade. Applies to entire tech, not just a specific 
                          effect header.
		Bit 0x80: Unused.
	Enemy Attacks: Possibly unused.
	Enemy Techs:
		Bits 1-4: Unknown.
		Bit 8: Unused
		Bit 0x10: Unused.
		Bit 0x20: Unused.
		Bit 0x40: Ignore Hit and evade. Applies to entire tech, not just a specific 
                          effect header.
		Bit 0x80: Unused.
Byte 3: Tech or Attack Type.
	Bits 1-8: Unknown.
	Bit 10: Enemy Vs Enemy Attack. Set on enemy attacks that target other enemies.
	Bit 20: Unknown.
	Bit 40: Tech. Set on every item in enemy and player techs.
	Bit 80: Player attack.
Byte 4: Bitflags. Relates to AI and element. A tech can only have one element.
	Bit 1: Unknown.
	Bit 2: Magical Attack, as used in AI.
	Bit 4: Physical Attack, as used in AI. A tech can be both magical and physical in AI 
               checks.
	Bit 8: Unknown.
	Bit 0x10: Fire elemental.
	Bit 0x20: Water elemental.
	Bit 0x40: Shadow elemental.
	Bit 0x80: Lightning elemental.
Byte 5: Unused.
Byte 6: Effect Header and MP Cost 1. For player techs, setting bit 80 will ignore the effect header
        and only load the MP cost. For enemy techs, this is done by setting a value of 0xFF.
Byte 7: Effect Header and MP Cost 2.
Byte 8: Effect Header and MP Cost 3.
Byte 9: Hit Effect 1. This loads the same data as weapon and armor effects.
Byte 10: Hit Effect 2.
Byte 11: Hit Effect 3.

The location in the ROM for each varies depending on the type. Offsets are listed in the following order: Japanese, English, Pre-release.

Player Techs: 0xC18A8, 0xC1BEB,0xC1B64
Player Attacks: At the end of Player Techs
Enemy Techs: 0x0C6FC9, 0x0C6FC9, 0x0CF608
Enemy Attacks: 0x0C8801, 0x0C88CA, 0x0C7B80

Status Bits[edit]

For techs which impact status the 3rd byte of the Tech Properties will determine which statuses changed. Each bit in that byte corresponds to a status these are listed below:


           positive/negative
Bit 1(80): beserk/stop
Bit 2(40): shell/poison
Bit 3(20): regen/unknown
Bit 4(10): unknown/doom
Bit 5(08): unknown/silence
Bit 6(04): protect/confused
Bit 7(02): unknown/sleep
Bit 8(01): unknown/blind

Graphics Header[edit]

Graphics headers have all the graphics data for techs. They are 7 bytes long, with the exception of enemy attacks, which are 6 bytes long, and player attacks, which are 5 bytes long.

Graphics headers are unique to each player tech, enemy tech, and item. Enemy attacks use one of two graphics headers, depending on the attack index. Player attacks use a header determined by the weapon equipped and attack type (ranged, melee, or critical).

Byte 1: Animation Index. This controls which set of animation and sound data is loaded. 
        This is not part of the header for player attacks. It instead loads one of three 
        attack bytes.
Byte 2: Sprite Packet 1. This determines which sprites are available to effect objects.
Byte 3: Sprite Packet 2.
Byte 4: Assembly Packet. This controls sprite animation and assembly for packets 1 and 2.
Byte 5: Unknown
Byte 6: Sprite Palette.
Byte 7: Layer 3 Packet. This controls all properties for layer 3 effects, such as
        *Lightning's lightning bolt. This is not used for player or enemy attacks.

The location in the ROM for each varies depending on the type. Offsets are listed in the following order: Japanese, English, Pre-release.

Player Techs: 0xD45A6, 0xD45A6, 0xD45A6
Player Attacks: 0x0D4015, 0x0D4015, 0x0D4015
Player Ranged Attack Byte: 0x0D4000, 0x0D4000, 0x0D4000
Player Melee Attack Byte: 0x0D4007, 0x0D4007, 0x0D4007
Player Critical Attack Byte: 0x0D400E, 0x0D400E, 0x0D400E
Enemy Techs: 0x0D5526, 0x0D5526, 0x0D5526
Enemy Attacks Set 1: 0x0D4926, 0x0D4926, 0x0D4926
Enemy Attacks Set 2: 0x0D4F26, 0x0D4F26, 0x0D4F26

Targeting Data[edit]

Two byte targeting data used to determine the behavior of the target selection. Enemy Targeting mostly relies on AI, using byte 1 to find a fallback target.

Byte 1:
	Bit 80: Hide tech selection menu when choosing target
	Bits 7F: Type of targeting at menu selection.
Byte 2: Type of targeting at attack start.

Offsets Pertinent to Techs[edit]

All offsets given in terms of an unheadered Chrono Trigger ROM.

0x02BD40 ~ 0x?????: Tech names and descriptions that appear in the character status menus.
 The data are arranged like so: FF NN
  FF: Tech index of a character's first tech.
  NN: First tech index of the next character's first tech.
  Thus, Crono's data is 01 09; 01 is the index of Cyclone, and 09 is the index of Marle's Aura.
  Magus' techs are encompassed by 31 39; perhaps 39 pertains to the double tech Aura Whirl?

0xC0230 ~ 0xC0236: Tech learning progress (00 - 08)
  Index of last tech learned. 

0xC0237 ~ 0xC023D: Techs learned (bitflags)
 Techs learned in the current group. 80 - tech 1.

0x0C15CF ~ 0x0C1ACA: Tech names (11 bytes each)
 See the alphabet section for appropriate values.
 Tech names are supported in Temporal Flux as well.


0x0C23EB ~ 0x0C247A: Some extra data for 12 combo techs.  
 (4th = Crono's Confuse power, 5th = Triple Kick power, 9th = Double Cure?, 
  10th = Grand Dream, 11th = Twin Charm?, 12th = Slurp Kiss)

0x0C253C ~ 0x0C2573: Tech MP cost (1 byte per tech)
 56 techs total (Cyclone through Dark Matter)

0x0C2577 ~ 0x0C257F: Redundant MP Costs (Confuse, Triple Kick, Life2, Charm, Slurp Cut, Cure2, Frog Squash, Charm, Kiss)

0x0C29D7 ~ 0x0C2AD6: "Stat increase" values 
 (The "Item Secondary" byte "04" points to this array): 128 elements, 2 bytes per element
 Byte 1 = Stats to change:
  Power ~ 80
  Speed ~ 40
  Stamina ~ 20
  Hit ~ 10
  Evade ~ 8
  Magic ~ 4
  Magic Defense ~ 2

 You can combine stats to change, but they will all be changed by the same amount.

 Byte 2 = Change:
  00 - 7F: Increase by 0 to 127
  80 - FF: Decrease by 128 to 1


0x3DA89D ~ 0x?????: Tech names and descriptions that appear in the character battle menus.
 The data are arranged like so: FF NN
  FF: Tech index of a character's first tech.
  NN: First tech index of the next character's first tech.
  Thus, Crono's data is 01 09; 01 is the index of Cyclone, and 09 is the index of Marle's Aura.
  Magus' techs are encompassed by 31 39; perhaps 39 pertains to the double tech Aura Whirl?

Lots of people need to be thanked for this, including Justin3009, Mauron, Maelstrom, and AdNova. The list will grow...
