Hacking Manually updating romfs.bin for backups

[huma_dawii]

Once you have the decrypted base, you can now run the command to merge with the update, using the titlekey for that update. Hactool does not let you use two titlekey, which is what would be necessary if the base wasn't decrypted.

But I never needed two keys to merge update with base, just the update key ._.

My miniguide was for stardew.

Ok xD i was just trying to see if that helps with XC2 and its updates.

 

[kevin_1351]

can someone help me find ARMS update

Stardew was a pain to update

First extract both nsp's and rename the largest nca's as stardew.nca and update.nca

Then run the command below



This outputs a plaintext base nca - no need for titlekey to work with it

then to merge the update to the base, using the command below or use @Assasin1990 's
Update_NCA.bat



this will create an updated and combined romfs.bin and exefs folder. use with your favorite layeredfs nro

hactool.exe -k keys.ini --titlekey=[insert titlekey for base] "stardew.nca" --plaintext=NCAID_PLAIN.nca

Is enough. You don't need the rest.

Help with merging more than one update? please? xD

Well my finding on the "Partition Type" mismatch proved that the merging only takes place if both .nca files 'Section 1 = RomFS partition type'

Issue I am still having is with all the DLCs having Section 0 as RomFS partition type... so i can merge .nca Section 0 with .nca Section 1

i can create .bin files from both .nca... but then can i merge 2x .bin files together? if so, then im sure DLCs can work

what about the good old copy /b command? xD that thing merges files just because!

This is what I got note how it created a file called "stream" in the exefs D:

You can't update XCIs magically, you can't even use hacbuild since you can't yet use custom NCAs

It feels really good to update games!
Just updated Wolfenstein II and it popped from 13 GB to 23 GB!
Btw dlc install becomes a pain if your regions don't match!

 

[Assasin1990]

wait are you saying DLC installation is possible? (via LayeredFS... not using SX OS)

because from my Xenoblade DLC finding.. hactool doesn't merge the nca files because the sections mismatch

You need to extract them as folders. The DLC can be extracted alone and will be merged with the existing romfs folder of the base game + the update.

hmm i dont quite follow... are you able to provide steps?

I'm able to extract the DLC .nca file into a folder, but how do i merge with the game?

 

[AlphaSapphire]

ok so do i take the biggest update/dlc to merge with the romfs?
