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. Some features from Persona 2 also make a return.

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 modify 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.
