Persona 5

Persona 5 is a main title in the Persona franchise. It's the long awaited sequel to Persona 4, featuring a new cast of characters who have the ability to "steal the hearts" of their adversaries. It uses a brand new engine with updated graphics and gameplay. Persona 2’s battle negotiations also make a return.

An updated rerelease titled Persona 5 Royal launched on PS4 only, which adds new story content and several quality of life enhancements, similar to P3FES and P4G before it.

A mod called Persona 5 EX, developed by DeathChaos, aims to backport some features from Royal to the PS3 version (but is by no means a complete backport). It also includes tweaks that un-hardcore aspects of the game, thus making mod creation easier on users. Some mods may require P5EX as a dependency.

Modding
Like Persona 4 Golden and Persona 3 Portable, multiple CPK archives comprise Persona 5's filesystem. You can either modify an existing CPK, or patch the EBOOT to load a new CPK that has priority over the contents of all other CPKs. (see mod.cpk). Persona 5's CPK files do not need to be compressed. The only requirement is that you must keep the filesystem structure intact. For instance, if you want to replace ps3.cpk/sound/bgm.awb, make a folder in your new cpk called sound and place the new bgm.awb inside.

It should be noted that there are duplicates/redundancies of things found in the files. Some of these files aren't used at all.
