Tech Properties[edit]

Each tech has certain properties associated with it. They start at 0x0C214B and are 12 bytes each.

Byte 01: Mgc Type, 01 Status Negative,  03 Time, 04 Status Positive, 46 steal.  Other values Magic Power if TechType= magic or numHits if techType=multihit 
Byte 02: Tech Type, 00 Healing, 01 Status Positive, 02 Status Negative, 03 Damage, 06 Stealing, 08 Multi Hit
Byte 03: If Tech Type is status related the bits of this determine which status gets added
Byte 04: Insignificant part of two byte hit%
Byte 05: Significant part of two byte hit%
Byte 06: Unknown
Byte 07: Higher values = less damage
Byte 08: Unknown
Byte 09: Higher values = more damage
Byte 10: Higher values make magic techtypes do more damage
Byte 11: Higher values make physical tech types do more damage
Byte 12: Unknown


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

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)
 The effects of this offset range have not yet been explored thoroughly.

0xC0237 ~ 0xC023D: Techs learned (00, 80, C0, E0, F0, F8, FC, FE, FF)
 The effects of this offset range have not yet been explored thoroughly.

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

0x0C1ACD ~ 0x0?????: Tech targeting. 2 bytes each.
 Some common values are:
  07 00: One enemy (Example: Confuse, Charm)
  08 00: All enemies (Example: Dark Matter, Ice 2, Luminaire)
  80 00: One ally (Example: Cure, Aura)
  81 00: All allies (Example: Heal Beam, Aura Whirl)
  03 00: One fallen ally (Example: Life)
  04 00: All fallen allies 
  12 03: Enemy area (Example: Cyclone, Dark Bomb)
  0B 01: Enemy line (Example: Slash)
  0C 05: Enemy line (Example: Flame Toss)
  11 02: Area around character (Example: Area Bomb, Tail Spin)
  1B 0A: Area around character (Example: Black Hole)
  13 02: Area around character (Example: Max Cylone, Fire Zone)
  0F 0B: Horizontal line (Example: Falcon Hit)
  00 00: One ally status (Example: Haste, Magic Wall)
  01 00: All allies status (Example: Life Line)
  13 06: (Example: Double Bomb)
  0D 01: (Example: Blade Toss)

0x0C214B ~ 0x0C23EA: ST Tech power: 12 bytes per tech, 8 techs per character.  
  If the tech heals, 2nd byte affects power. For attack techs, 10th byte affects power.
0xC214B = cyclone attack
0xC2157 = Slash
0xC2163 = Lightning 
0xC216F = Spincut 
0xC217B = Lightning 2
0xC2187 = life 
0xC2193 = confuse
0xC219F = lumiaire
0xC21AB = aura
0xC21B7 = provoke
0xC21C3 = ice
...

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


0x0D45AD ~ 0x0D4925: Unknown tech data; 7 bytes each (127 techs). May point to graphics and sound data.
 The bytes are structured as follows: aa bb cc dd ee ff gg
  aa = An unknown tech index. May point to two-byte "slots" beginning at address 0x0D5EF0
  bb = 
  cc =
  dd =
  ee =
  ff =
  gg = 
 Crono's first tech, Cyclone, will be used to illustrate. Its 7 bytes in this region are: 01 DA EF 20 01 01 FF
  01: Points to the second "slot" in offset range 0x0D5EF0 ~ 0x??????

0x0D5EF0 ~ 0x0D5FDB: Possible pointers to sound and personal tech animations. 2 bytes per tech.
 These do not seem to pertain to spell graphics packets (i.e., exchanging Cyclone data for
Lightning causes the Lightning sound to be played and causes Crono to act as if he is casting
Lightning, but the sparkles and Lightning bolt graphics are still Cyclone slashes).
 The extent of this data is unclear. The ending point may not occur until 0xD612F.

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, Maelstrom, and AdNova. The list will grow...
