Not sure everyone will be your friend if you cheat but theres an updated release of the Cheat App from the Other day:
Great little app, works well. Within seconds, I was able to max out PP on the Dead Rising 1 HD Remake and I'm no expert so if I can do it, anyone can do it!! If anyone is used to RTM modding on ps3 or the cheatengine on PC, you should be able to pick this up very quickly. It is a very simple tool to use. FYI, if anyone cares to dig in, PM me your findings and I'm going to start a spreadsheet and will upload to google docs to keep track of codes.
Our admin @GaryOPA was nice enough to give us a section on the forums so I've been adding to that instead. Please feel free to pitch in!!
EDIT: Getting this to work on 4.55 is a little more complicated than on 4.05.
Download the 4.55 cheater (attached below) Download jkpatch for 4.55 (attached below) Extract both Copy the payload.bin from jkpatch to the PS4 Cheater directory and replace the payload.bin that is there
Go to webpage or userguide on the ps4, click on the 4.55 menu, then click on original
