PSI data table
Game MOTHER 3
Start Address 0xE1908
End Address 0xE5107
# of Entries 256 (0x100), only 100 used
Entry Length 56 bytes (0x38)
Total Length 36864 bytes (0x3800)
Back to the ROM map

Overview

The PSI data table contains parameters for each PSI move in the game. The ordering is consistent with the game's internal PSI names listing.

Format

Each entry in the table uses 144 bytes.

Field listing

  • 00-00 (01) = [ A ] PSI number

30  | [ K] [                ?               ]

Type

The type value determines in which category it is placed:

00: Offense
01: Recover
02: Assist

Damage type

There are four damage types, and they correspond to weakness values 0x0F through 0x12 in the enemy weakness table:

00: PK Love, Starstorm, Ground
01: PK Fire
02: PK Freeze
03: PK Thunder

Target

The target value seems to affect how the ability is targeted. Known values are:

01: One party member
03: All party members
04: Healing Ω
0D: One enemy
0E: All enemies
0F: One strike
10: Two strikes
11: Three strikes
12: Four strikes
13: Multiple strikes (PK Ground)

Low/high amounts

These affect the bounds of damage or recovery for abilities based on such.

Affliction

PSI may afflict a status condition on its target. The affliction value selects an affliction from an enemy's list of weaknesses. Since weakness 0 corresponds to Poison instead of null, you actually need to add 1 here. For instance, PK Freeze has an affliction value of 10, so that it may induce solidification (which is weakness 9).

There is also an affliction chance. Whenever using a PSI spell, the game uses the following formula to determine whether or not an ailment is afflicted:

Let W = enemy weakness value against this affliction
   (W := enemy_weakness_table[affliction_value - 1])

Let C = affliction chance

Let R = random number from 0 to 99, inclusive

If R < (C * W / 100): status afflicted
Else: status not afflicted

For example, say you're using PK Freeze against a Monkalrus. The Monkalrus has a solidification weakness value of 30. PK Freeze's affliction chance is 8. So,

    If R < (8 * 30 / 100)
or, if R < 2.4
or, if R < 2 (the game does not use fractions here; the quotient is always rounded down)

That is, PK Freeze has a 2% chance of solidifying a Monkalrus.

Animations

These affect which visual animations play. It is not fully known how these correspond to the battle animations entry table.
