RPCS3 is far from stable or complete, but it runs some games well enough. As far as Ni No Kuni is concerned, it runs in-game for most people. I had some crashes at times, but it played okay with some graphic glitches. I bought Ni No Kuni when it first came out and have a CFW PS3 for cheats, but I don't play console's that much anymore. I did attempt some console cheating with it, but the Infinite HP option in Artemis affected the first boss for me.
So, I have some pointers to Current HP and MP that you can freeze for Infinite HP and MP for now. It was made using RPCS3 (the 3/1/2018 build) (0.0.5-6491). I am using the PSN version of the game (NPUB30932). Like I said I bought the game already though way back when it came out.
I'm not sure if I can do many more options, but I thought I would try playing some of the game and these options are probably enough to get through the game without dying. I am looking forward to Ni No Kuni 2 this month and it has an official PC release, so things should be easier with it.
I forgot to mention, you need to setup 4 Byte Big Endian custom types for the table to work right. Get the code from DarkByte in this thread: [Link]
EDIT 1:
I added a pointer to Guilders (Money). I am getting random crashes trying to play in in RPCS3, so I might have to resort to playing it on CFW PS3 with the available cheats there. It does appear addresses don't change, so there's probably more things that can be added like items and things, but again I may stop playing on the emulator for now.
