Persona 5/patch1ps3.cpk

The patch1ps3.cpk is an update CPK that was available digitally for the Japanese version of Persona 5 shortly after launch. It contains some of the DLC models for Personas and party members, as well as a multitude of files that had been altered in some way. This includes bustups, events, sounds, scripts, and a texture for one of the lessons in class.

Modding
While this CPK is a great alternative to modifying most of the other CPKs, as it's small and not essential to running the game, patch3ps3.cpk is optimal as it only contains a couple altered script files (weighing a mere 40 kb).
