Hacking Manually updating romfs.bin for backups

[GOTBLZ]

Wait, sorry, no you were right, I just checked my Kirby one again, and it's the same as how I extracted it... hmm, i'll see what hactool's NCA problem is.

Didn't you say your Kirby shows the 2.00 on screen?

 

[GOTBLZ]

I meant your key you had was right, so it cannot be that, I didn't mean that I just noticed my game didn't update... lol. The file your trying to use as the update is an nca format?

Yes it is an NCA update file. What I don't know if the one I got from the SD card (downloaded by the game itself when I put my real card inside the Switch)

I just tested with hactool telling it I was giving it a NCA file, but instead giving it an xci, and it gave me the exact error you had, so it's gotta be one of the files aren't an nca

So @GOTBLZ
What size is the kirby update? the biggest nca I'm seeing in the update folder is 14mb

The update doesn't come inside the cartridge xD comes from Nintendo Servers.

Are you meaning you grabbed the .nca folders with the 00 files in them? They aren't nca format, they need to be converted to true .nca format first, https://gist.github.com/khang06/84aabeac507fa99a676d22bb6120cea8 that should give you a guide on how to do that.

The Kirby update was around 300MB

Yeah I just copied the update from the SD CARD to my PC xD

I just spent like 15 minutes looking how to pm you, but I discovered I cannot until I have 10 posts, lol, so do you want to pm me?

Ugh... I remember getting something like that myself once or twice, cannot remember what I did to solve it.... try googling it, if I remember what I did, i'll let you know...

Sure!

 

[GOTBLZ]

Just to give everyone that little bit more encouragement... lol

 

[Zumoly]

This is funny but here's a tip: I never put the title key when extracting nca files and it always works!

You don't need to for nca's out of your backups, but you will need to for the updates or else they won't extract. Every update has a different key too, so its not like you can just save that key under Kirby Star Allies...

Oh...I see!
Edit: @GOTBLZ do I need to manually type the commands or can it be worked out from a bat file?
Edit 2: The experiment is a success! Along the way I learned some new stuff that might come in handy when installing DLC. Kudos @GOTBLZ for the clever commands!

I think the Nintendo folder puts files under the NCA folder of the app. Try finding the one for Kirby.

Yeah but you have to follow a WHOLE procedure to get them out of the SD card in the right format.. Is not so easy as copy and paste xD
