in the file i put it will be what keys i have

Can't give you a direct link to the keys, but Google is your friend.
Hint: search for "key_area_key_system_07"
also search for "key_area_key_system_08"
Build yourself a nice up to date keys.txt file (or prod.keys)

i used lockpick rcm to get the keys, do i need more

 

[Dust2dust]

Lockpick is another option if your Switch is running the latest update. If not (like me), the Google option definitely works.

my switch is on fw 8.1.0 and i used lock pick and i linked what keys im using do i need more

 

[Dust2dust]

The file you uploaded has no keys. I assume you edited them out. If not, Lockpick didn't work properly. Try again. Or just use Google. (google is faster)

You're not using hactool properly.
Those key mismatch errors don't matter because hactool doesn't use those.
In a nutshell it's saying "hey there are keys here that we can't match to any we use".

To extract the NCAs of the NSP you need to run something like:

hactool -x -tpfs0 --pfs0dir="<Output path>" "<Path to NSP>"

Then on the largest NCA you would run the following to extract the game romfs:

hactool -x -tnca --romfsdir="<Output path>" "<Path to NCA>"

when i did the first command i still get the same error and no files get put in the output path

What is the exact input you're entering?

I might know what's wrong but I want to be sure.

 

[nopo]

hactool -x -tpfs0 --pfs0dir=D:\Switch\games\pokemon D:\Switch\games\lets go pikachu.nsp

 

[8BitWonder]

hactool -x -tpfs0 --pfs0dir=D:\Switch\games\pokemon D:\Switch\games\lets go pikachu.nsp

Enter:
hactool -x -tpfs0 --pfs0dir="D:\Switch\games\pokemon" "D:\Switch\games\lets go pikachu.nsp"
With those quotation marks added.

They shouldn't be necessary for your outpath (though I recommend them anyway) but you certainly need them for your NSP path.
As it is right now it's looking for "D:\Switch\games\lets" when you don't put quotations around it.

thank you

i don't know where to put that command

 

[8BitWonder]

i don't know where to put that command

Open a terminal/command prompt in whatever directory you have hactool and enter those commands there.

@8BitWonder can you please help me fixing this line
hactool --basenca="$basenca" $updatenca --romfsdir="romfs" --exefsdir="exefs"
Here's the Error:
Failed to read from Base NCA RomFS!

Been a while since I've touched hactool, try the following and see if it makes a difference;

hactool -x -tnca --basenca="$basenca" --romfsdir="romfs" --exefsdir="exefs" "$updatenca"

Also make sure you have the correct base/update titlekeys in your title.keys file if they're encrypted.
