Step 1 - PreparationStep 2 - DecryptionStep 3 - FinalizingExtras

1. 
   
   1. Download hactool: https://github.com/SciresM/hactool/releases/
   2. Extract the following next to hactool.exe: https://gbatemp.net/attachments/decrypt-xci-v2-1-zip.131659
   3. Make sure your keys are in keys.ini filename and format and is next to hactool.exe aswell
2. 
   
   1. Put the .XCI you want to decrypt next to hactool.exe (Important)
   2. Drag the .XCI onto the Decrypt-XCI.bat
   3. Let it do its thing, it could take a while
   4. Once you see "DONE!" your done!
3. 
   The new folder xciDecrypted next to hactool.exe is now the romfs and exefs of the xci decrypted.
   romfs in xciDecrypted/romfs.bin and exefs in xciDecrypted/exefs
   The structure is 100% ready to copy and paste into sd:/atmosphere/titles/{titleid}/ for Backup Loading/LayeredFS Mods.
   (but you still need to rename the folder to the titleid and edit the main.npdm)
   To use this with Ryujinx, drag the xciDecrypted/exefs folder onto Ryujinx.exe (No idea about Yuzu).
   
4. 
   
   • If you want the Batch file to close once its done, remove the last line (pause >nul) and save.

Thanks to gdkchan for the original script, since the original script, I have HEAVILY modified it.

[StripTheSoul]

Hm, weird, it worked with all other XCIs, but with Sonic Mania Plus, Decrypt-XCI-v2.1 says 'file not found'...?

Decent guide, but could be a bit more in depth.
For example, you could be more specific about "Make sure your keys are in keys.ini filename and format and is next to hactool.exe aswell", what exactly does "keys.ini filename and format" mean? It's not clear to noobs.
Also you could explain how to figure out the title ID in order to rename the folder (or link a thread/guide/website that explains how to do so)
Other than that, I think it's good

Doesn't seem to work with Octobath Traveler , it extracts just the romfs.bin alone inside the folder and that file alone is about 3GB

Yeah, me too. I'm getting section 0 is corrupt which I think is causing it

did you write this? if so could you add a title id patcher thanks

I added a title ID finder to this one and some other stuff to make it a little easier.

New build of hactool can now decrypt newer games like Octopath Traveler.

[ArcAngl]

I am really new to this, I was able to extract it correctly but how do you play it on the switch after you have it extracted. I made the correct folders in atmosphere.

 

[Trunsel]

Hello, im new here i understand this decrypt make exeFS folder and Romfs.bin but i want romfs FOLDER for PKNX, how can i make this?

 

[ArttyRios]

I don’t have a switch to get the keys, don’t have what to do?

 

[Deastrumquodvicis]

The only things in my xciDecrypted folders are a .cert and a .tik. I haven't been getting hactool to open up at all, not even when I drag-and-drop, so I'm not sure what's going on with my process.
