How the hell do I extract an NSP for an update file? I'm trying to extract the game files in an attempt to mod Pokemon Shield, but I cannot for the life of me figure out how to get the damn NSP open. I feel like I need someone to explain to me like I'm a complete idiot what I'm missing here.
I have dumped my original game cartridge in both NSP and XCI formats, and i managed to use the dump tool to get the romfs from the base game. But then I find out that PkNx doesn't work for anything less than version 1.2.0, so I'll have to include the update files. So I dumped that to an NSP, and that's where I'm stuck. I can't seem to crack open this file and get what I need. I've tried hactool, unpack, yuzu, and a million other random things I found.
And yes, I dumped pretty much everything I could think of from my switch, including prod.keys, title.keys, the fuses, the nand, etc. No matter what I try, nothing works. I've been working on this literally all day and have accomplished precisely dick. I need a simple step by step process of exactly what I need to do to be able to mod this game in PkNx.
