I don't take any credit for this, but I think some people here don't know about this (I didn't know about it), this is from the official yuzu discord that you can find here: https://discord.gg/u77vRWY

1. I'm assuming you already have access to the Homebrew Launcher.
2. Put the swupdatedumper.nro in SD:\switch
3. Boot into CFW.
4. https://imgur.com/a/OLw2irt
5. Open Album (which will open up Homebrew Launcher)
6. Launch the swupdatedumper.nro
7. Dump Partition 2 (this will take while depending on how big the game is)
8. Now get the SD and navigate to SD:\dump_2
9. In that folder, you'll find all the necessary files.
10. Copy all the contents of dump_2 paste them into a directory of your choice.
11. The next part is IF the dump comes in multiple files with the extensions .nca.0x (x can be any number starting at 0), if it doesn't come in multiple files skip to "Now extract/decrypt with Hactool." part.
12. [Now you'll need to merge the .00, .01 and the .02 files.
13. make a .bat file and type in;
14. copy /b X.nca.00 + X.nca.01 + X.nca.02
15. Replace the X with the name of your .00, .01, .02 files for example;
16. copy /b 08c1d23a902a841b497f7be217c8ad6d.nca.00 + 08c1d23a902a841b497f7be217c8ad6d.nca.01 + 08c1d23a902a841b497f7be217c8ad6d.nca.02
17. the output file will be the X.nca.00 file.
18. Rename output file to X.nca. ]
19. Now extract/decrypt with Hactool.
20. run "hactool --exefsdir=output --romfs=output/game.romfs NCA"
21. NCA is the path to your X.nca
22. And now you'll have a bootable game dump!

Good Luck ^^
there is nothing you can do, with those dumps for now, except running some games in yuzu (with 2 fps lmao)

Normally you will get an error about invalid nca file header and this is because the nca is encrypted and you have to add a keyfile with Nintendo Switch keys.
You have to search a bit on google to find them and after you created you file you can add it to your command like this:

-k "yourkeyfile.extension"

Example:

hactool -k "keys.dat" --exefsdir=output --romfs=output/game.romfs "e0d36953372443ccd6582f4ca5d3351e.nca"

here is a sample: https://gist.github.com/nicoboss/967cd250d3969e1c4610c54e3186193b (just hashes of the keys, a little hint, you can search the hashes on google, if you find a key you should search that key in google and with some luck you should get to a big collection of keys....)
In the file are spaces and lines starting with a semicolon (';') ignored.

 

[SirNapkin1334]

you are missing the "keys"

you have to create a file with some keys inside (dunno which of them but there is a certain romsite with a lot of keys....)

you can add the file with

(spaces are ignored and lines starting with a semicolon (';')

You can’t post that link here.

 

[Gnarmagon]

Yes, you can use Pegaswitch which now has support up to 4.1.

By booting into CFW it means Hekate not Pegaswitch -.-

You can’t post that link here.

I can read carefully the link I posted

No, I mean, posting that is against the forum rules - you can't post keys or links to them.

like I said read exactly what stands in this link on the gist....

The user was asking if there were other ways of booting into the homebrew launcher without the CFW, Hekate.

 

[trainboy2019]

Sorry if this is a dumb question, but are we able to extract the romfs from these dumps? If so, how would I do that?

 

[Dan-the-Rebirth]

so with that we can only make nca dumps, but will we be able dump the games in a playable version with this soon(xci for use with cfw)?

 

[CraftLegend]

Sorry if this is a dumb question, but are we able to extract the romfs from these dumps? If so, how would I do that?

I think it is possible with Hactool and HACToolGUI.

 

[trainboy2019]

Thanks! I'll give it a shot

UPDATE:
It worked!

OOOPS
im blind

 

[Shinygati]

So is the end result supposed to be a single .nca file or just the romfs and other files that were extracted? i'm not getting an output .nca file at all apart from the first step when merging them but everything else up until that point works fine.

your post is actually stupid,
it makes sense to keep this forum legal and piracy isn't okay so yeah...
and this Forum isn't about circumventing copy protections because 98% can't code at all so yeah....

When I select "Dump Partition 2", I get "GetGameCardHandle Failed". Also, is there any way yet for dumping titles installed on NAND or SD?

Nand and SD dumping isn't possible afaik

System crashes after I exit the dumper so IDK

 

[LordVe]

Is there any way anyone can update the app to dump the entire cart as an XCI file?

 

[Deleted User]

What if i have multiple files without extension nca.0x

READ BEFORE POSTING !!!!!!!!!!!!!!!!!!!!

1. The next part is IF the dump comes in multiple files with the extensions .nca.0x (x can be any number starting at 0), if it doesn't come in multiple files skip to "Now extract/decrypt with Hactool." part.
