Help with Persona 5 Royal USM key?

Post by ReclusiveEagle » Thu Sep 30, 2021 2:17 pm

So I've extracted both Royal on PS4 and normal Persona 5 for PS3. PS3 I have no issues decoding the USM video files.
Persona 5 Royal however I can't extract. Apparently they encrypted the files.

Now that being said, apparently USM HCA keys are extremely easy to figure out using hex editors.
Unfortunately, I know nothing about Hex editing and wtf 0x20 even is. Can someone help figuring it out?

According to this post https://shrinefox.com/forum/viewtopic.p ... =870#p870/, the key is 00000000001C87822
(yes 17 characters. idk why)

Unfortunately (again) this just leads to a horrific mess of noises on "decryption". Obviously its the wrong key.

Here is a link to my Google Drive https://drive.google.com/file/d/1sWlHkf ... sp=sharing
You will find Mov000.usm (opening cinematic). I know this USM has both video and audio so that will help with @SFA searches

This key you mentioned is for the different version of the game
Try this instead:

Code: Select all

crid_mod.exe -b 00000000 -a 035B6784 -v -x -i mov000.usm
