Editing herostat and npcstat doesn't work the same as pc version I tried but will editing the main items xml at least work
Herostat works, but some like NPCstat & items, even review_path loading screen requires edits on the fb files which contains them
Well with xml2 psp a took all 3 fb files in the dead zone folder put a modified npcstat in each one and when the area loads it's just a black screen with some of the his showing
You need to edit the rest of the fb maps which contains npcstat in it
So it's not worth modding
Kinda worth it, but needs more time to extract from & repack to fb files when it comes to add new mods. It's your decision
i think i will try but probably going to take my time
