I'm trying to randomize pokemon shield using pkNX, but even though I extracted the RomFS and ExeFS using NXDumptool, It doesn't recognize it when I drag them over to pkNX. I just want to know how to randomize the game properly.

I know, but I want to be able to apply my own custom settings, I'm just not sure how to operate pkNXit's already done by stoned unless pknx randomize the table randomly
