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.

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

No, he says he has multiple files but they aren’t .nca.0x files, there something else (presumably .nca).

goddamn are u kidding me ?
It literally stands there: skip to the hactool step and there stands choose the biggest NCA, so yeah what is so difficult to understand ?
OR you can stop using this because it's outdated by Waindumper (https://gbatemp.net/threads/wain-cart-dumper-nx-v0-0-2-xci-dump-tool.506798/)

is this fat32 or exfat only? my switch says mount gamecard failed 320002
any idea? micro sd card is formatted to fat 32

Is there a way to do this with eShop games? (probably been asked before but I don't have time to look)

We cannot dump eShop games directly but you can dump any of your downloaded titles with this guide: https://gbatemp.net/threads/dumping-your-titles-from-sd-a-bit-advanced.507821/

The end result will be in .NCA format which you can use this tool to convert into .NSP which is the file format for eShop titles: https://gbatemp.net/threads/nspbuild-build-nsp-files.509816/

If you want to dump eShop titles straight from Nintendo's servers while risking a ban, you can use this software to do that (which requires your console's unique certificate beforehand hence the ban risk): https://gbatemp.net/threads/cdnsp-download-repack-your-games-updates-and-dlcs-to-nsp.510096/
