Chrono Trigger's data tables (dscotton's ct_disassembly)

Each of the 256 enemy slots has 23 bytes of stats, which the battle copies into the enemy's combatant record as it loads the enemy: HP (two bytes), level, five status bytes, Stamina, Speed, Magic, Hit, Evade, Magic Defense, Attack and Defense, four elemental bytes, and three more bytes. HP goes to both current and maximum HP. chrono-trigger-tables/enemies

Names are the ROM's own text; a slot whose name holds no text is left blank. The loader writes the five status bytes into the second of the combatant record's two status sets (record bytes $22-$26) and copies the last two of them into the first set; bytes 8-19 go to record bytes $37-$42 and bytes 20-22 to $19-$1B. Stat names are the disassembly's labels for the combatant record's bytes $36-$3E (Power, Stamina, Speed, Magic, Hit, Evade, Magic Defense, Attack, Defense), which the stat boost code bears out for Power at $36 (capped at 99) and Speed at $38 (capped at 16); enemies have no Power byte. The elemental resistance code reads the four elemental bytes, $3F-$42, in the order of the attack element's bits $80, $40, $20 and $10, which the disassembly names Lightning, Shadow, Water and Fire; $04 is the common value. Status and elemental bytes are listed in hexadecimal.

Each of the 256 enemy slots has 7 bytes of rewards: experience and gold (two bytes each), the item it drops after the battle, a second item, and tech points. After a battle the game adds each defeated enemy's experience, gold and tech points to the totals, then its drop unless the drop byte is 0: when the drop and the second item differ, the drop goes on the list of items won only if the enemy's drop flag is set and a roll of 0 to 99 comes under 90; when they are the same item, it goes on a second list without a roll. Each list holds three items; an item already on a list is not added again, and one that finds its list full is lost. chrono-trigger-tables/enemy-rewards

The disassembly's layout names byte 4 the charm item and byte 5 the drop; the battle-end code reads byte 4 as the drop. A helper the disassembly ties to Ayla's Charm takes byte 5 when a check it runs first succeeds and the first of the enemy's two item flags is set, and otherwise byte 4 when the second flag is set, clearing the flag it uses. Item names are the ROM's own text.

The 89 weapon slots ($01-$59) each have a six-byte record (flags, price, who may equip it, a stat bonus, and an element bonus) and a five-byte one whose first byte is the weapon's attack; the menu takes the equipped weapon's as the weapon attack it works the character's attack from. chrono-trigger-tables/weapons
