This page contains notes for the game Persona 4.
Enabling the "Awakening Eye"#
To set a Persona to have the eye symbol show up, you need to set the 4 bit in the first 2 byte value of a Persona's data. For example in the Japanese version of the game, the data for the Personas the player has starts at roughly 007A6810 and the byte needed to change for the eye to show up is at 007A6818. For example setting this byte or the relevant byte for any Persona data including party members to 05 00 will cause the eye to show up.
This value is also used to set if a Persona slot is filled or not with the 1 bit.
