The Enemy Configuration Table stores most of the data for enemies which is used inside battles. The first enemy is named "null" and has an index of 0. Information about where enemies spawn is in the enemy placement data and spans a few tables.

Format

"The" flag

If the "The" flag is 1, then the word "the" is put in front of the enemy's name whenever it is mentioned in combat.

Name

Name of the enemy in plain EarthBound text.

Gender

The gender of the enemy indicates which pronoun should be used when referring to it: male (1), female (2), or neutral (3).

Type

The elemental type of the enemy. Enemies can be normal (1), insect (2), or metal (3). This changes the affects of certain items.

Battle sprite

The sprite to be used in battle to represent this enemy. Note that byte 0x35 determines the palette used.

Out of battle sprite

Run flag

If true (1), then the enemy will run away from the player if the player's level is greater than the enemy's level.

HP

The number of hit points the enemy has. That is, the amount of damage which must be dealt to the enemy before it dies (unless the enemy heals itself).

PP

The number of psychic points the enemy has. Psychic points are expended when using PSI. If the enemy runs out of psychic points, they cannot use any more PSI.

Start text pointer

  • Length: 4 bytes (0x4)
  • Offset within entry: 0x2D-0x30

Pointer to the text shown when you start a battle with this enemy.

Death text pointer

  • Length: 4 bytes (0x4)
  • Offset within entry: 0x31-0x34
  • Range of values: 0x00000000-0x00FFFFFF, but it must point to valid text; may or may not require a pointer to the ROM as opposed to RAM

Pointer to the text shown when you defeat this enemy.

Battle sprite palette

  • Length: 1 byte

  • Range of values: 0-255 (0x00-0xFF0), but above 31 (0x1F) is garbage

The palette used for the battle sprite. Only values 0-31 (0x00-0x1F) are meant to be used; higher values go into other non-palette data, but still work and therefore may be useful.
