Now "we" can just grab the nca/nsp game + update, use a common update key (easy to find) + LayeredFS and play any game... In skillful hands, that's will be a game changer...

Don’t quote me on that

I sure as hell hope so!

What?

 

[Leozairus]

What?

now you can extract eshop titles without the 'unique key', just grab a common key and apply an update

I have a question, my update for DOOM is split in 3 files... D: how will I be able to dump it into one single .NCA?

 

[Mat37]

Don't know what to do now
EDIT : Ok i wasn't using the right version of hactool

What does that even means?

 

[ShaytheStar]

Did you check to make sure that the SD card is the same drive letter, and make sure the nca folder is in the same folder as the hexadecimal folder?

Yes, and yes, and it is. By the way, sorry for such a late reply. I left this typed out but unsent like an idiot, haha.

Evertime I get this error:

[WARN] prod.keys does not exist.
Error: NAX0 key derivation failed. Check SD card seed and relative path?
Done!

after runnung:

hactool -k keys.ini -t nax0 --sdseed=sdseed(which is 100% correct) --sdpath="registered/00000090/b201291d3e099872debd1c1870572cc3.nca" --plaintext=game.nca "G:/Nintendo/Contents/registered/00000090/b201291d3e099872debd1c1870572cc3.nca/00"

my keys.ini contains this:

master_key_00 = "master_key_00"
master_key_01 = "master_key_01"
master_key_02 = "master_key_02"
master_key_03 = "master_key_03"
header_key = "header_key"
aes_kek_generation_source = "aes_kek_generation_source"
aes_key_generation_source = "aes_key_generation_source"
key_area_key_application_source = "key_area_key_application_source"
key_area_key_ocean_source = "key_area_key_ocean_source"
key_area_key_system_source = "key_area_key_system_source"
titlekek_source = "titlekek_source"

Is there something missing?
It worked with extracting files from nca files from xci files with hactool.
Please help me!

 

[Khangaroo]

replace --sdpath="registered/ with --sdpath="/registered/

 

[Mat37]

Or use the new tool i guess

 

[Zyphron]

replace --sdpath="registered/ with --sdpath="/registered/

Still the same error...

 

[Zyphron]

Or use the new tool i guess

It worked!
I used the automated way to get the nca files and then ran this in a cmd window:
hactool -k keys.dat game.nca --titlekey="titlekey" --romfsdir="direction\"romfs --exefsdir="direction\"exefs
And I got all the game's files!

 

[Zyphron]

While extracting Super Mario Odyssey's Update (1.2.0) files it extracted the exefs but not the romfs with the following message:

Note: cannot save BKTR section without base romfs.

Is that normal?

It extracted again only the exefs but this time with no error message.
(hactool -k keys.dat game_update.nca --titlekey="titlekey" --basenca=game.nca --romfsdir=D:\NintendoSwitch\Tools\HACTool\SMOUpdate\romfs --exefsdir=D:\NintendoSwitch\Tools\HACTool\SMOUpdate\exefs)
