Offsets Pertinent to Techs

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?

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)

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

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.

Tech Memory Values

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 and AdNova. The list will grow...
