extract the base game + game update romfs and you'll get a file called pakchunk0-Switch.pak which needs to be unpacked using the PC version .pak extraction tools for unreal engine with the extraction script for FighterZ PC version. I haven't figured out how to repack it so that it will be the exact same size as the original unfortunately; so when I tested repacking it, the size was wrong. I guess it's compressed to around 6 gigabytes and extracts to about twice that size. Unpacking and reverse engineering the game files in the romfs isn't the issue. It's repacking it so that mods run from it with LayeredFS. idunno maybe try packing mods into pakchunk1-Switch.pak so it overrides data from pakchunk0-Switch.pak like how in just the base game for Xenoverse 2 replacing empty dummy data cpk files worked for overriding data in the data cpk file (but doesnt work the same with game updates because those dummy files became used for new game data)?
Here are some threadsHow do you extract the Swicth game files to start off with extract the nsp or extract from the xci?? What tool? I would really love to learn how the people that got the shading mod to work, did exactly that, extracted game files, repacked game files and it works. I would love to port over some stuff to the switch from pc just like they did.

@supermariorick post is outdated as we can already repack normally and even create compressed patches that make repacking unnecessary.
Shading mod is packed with u4pak to not compressed package, so it's bigger than it could be with my tutorial.
