Yow Razor, i don't know how to thank. The way you describe is so clear, I really appreciate that.
I stuck at one certain point. I've put the PBOOT.PBP file to NPUH90024 folder and I'm not sure if it's that what you meant, coz after that I back upped the game on to my PC and restarted Vita but the TNV bubble doesn't appear. What am I missing?
