Hacking Having trouble repacking decompressed files into a NCA

[ItsTheSky]

Hello there I'm looking for help about hacPack; my goal is to edit a file inside an NSP game.

1. I've extracted NSP's NCA files using NSC Builder
2. Those NCAs has then been decompressed also using NSC Builder, into plain files
3. I've edited what I wanted, but then I want to get back the modified NCA file to build the new NSP.

I've tried using hacPack but while the original NCA file (as well as the decompressed folder) is ~5Go (it's a Program NCA, thus it got exefs + romfs + logo), hacPack makes a new one that's only about ~20Mo, so I guess something's wrong, but I can't see what may be wrong. I've triple checked my keys from my switch, the folder pointed for the 3 NCA content and the title's ID (Krtdl deluxe), but nothing's changed. Any idea why I have this issue?

Also, I do not have any logs output (it's literally blank, before, during or after the process).

If you use hacPack from the command line, it spews plenty of status text, including every file it adds to romfs

The issue is that the hacpack command seems to fail or shut down by itself without any further logs. Here are the details of what I'm doing:

B:\Kirby>hacpack --type nca --ncatype program --titleid 01006B601380E000 --exefsdir "NCA/exefs" --romfsdir "NCA/romfs" -o "./output" -k keys.txt

And this is what my NCA folder looks like:
- exefs folder contains files:

- romfs folder contains tons of stuff (this is also where I edited my level's data). It's about 4,8GB in size (according to FileTree)

Once the command is executed and stops on the "Calculating metadata" line, I have a Program.nca file generated, which is only about 20MB (so I guess it only compiled stuff from exefs and skipped romfs' stuff?)
