Homebrew RELEASE [OFFICIAL] 4NXCI - A tool for converting XCI to NSP

[The-4n]

Total noob on this how hard is it to make a nsp from xci as I know nothing of python and just wondered what all I need to do this by chance

there's no need to have knowledge about python
you just need to have switch keys, you can find a guide if you look at this topic pages

Ok, i've done some research on this post, and i dont find any post that can answer my problem.

First i had a switch v.3.0.1 i converted some games with my key and all worked well.

Yesterday i try to convert Octopath Traveller, i see that i need to update do v5.x.x my switch. I've done that and get my keys after the update.

Since then i am unable to install any game with tinfoil... i am unable to convert them with 4nxci but when i try to install them on my console i have always an error with bad ID....

did my keys could be the problem ?

i think you meant you are able to convert the games with 4nxci but you can't install them with tinfoil right?
first of all, make sure that you are using the latest version of your cfw and it comes with sig patches
after that grab the latest version of tinfoil and use it to install the converted games
make sure to remove fs_mitm.kip cause it cause lots of problems

 

[naddel81]

does the install order really matter? haven't experienced a problem, yet. I rename all my nsps to GAME.nsp/GAME(UPD).nsp and GAME(DLC).nsp.

sometimes
better to follow this order when you want to install nsps: 1- game 2- update 3- dlcs

thans for the info @The-4n, i use the latest SDfilesv801. I boot ReinX, i was sure that sig patches was with it. i will check if it is or not.
I use the latest tinfoil and latest 4nxci v1.20

i will check too for the fs_mitm.kip file, i suppose i have to remove the files in sysmodules directory ?

thanks for the support

you need sysmodule files for your cfws
just remove fs_mitm, it's known to cause lots of problems

I grabbed the cert file from BOB, renamed it to keys.dat and when I try to convert any XCI file, I get this error: Invalid NCA magic!

Guessing using that cert file from BOB was not the right thing to do? If I need to provide different keys, could somebody post a quick, step-by-step, guide for what keys 4nxci needs?

tried to install my converted games with hekate CFW and works like a charm, so the problem was not my keys but the sig patches that was not working with ReinX, maybe i will try RajnX, but i dont think he have payload for trinket...

thanks for your great support !

4nxci v1.20 is not creating DLC nsp with Sonic Mania Plus as it does with V1.10.

new version is out, v1.21

it fixes the conversion problem for xcis with 1 dlc (thanks @Bigjokker for the report)

[DollyWhipDoll]

Thanks for your time.
Seems like there is not much choice than to update the FW.

Someone, somewhere said OcTrav does work on 4.1, definitely do not update for it.

Never mind. Turns out my keys.dat was invalid. Working fine now!

[rvkasper]

XCI works - keys also worked using SwitchSDTool to make working NSP files out of Super Mario Galaxy and Oxenfree from my NAND... ugh wtf

@The-4n I feel dumb! I didn't have space on system memory apparently - installed fine to MicroSD! Misleading error Thanks for the prompt responses much appreciated keep up the good work.

 

[benserwa]

What did you do? How do you get keys.dat?

 

[BillyJo]

@benserwa

Theres some method to get your keys:
1- (easiest) - With the apps called Kezplez-nx.
Get the apps (https://github.com/tesnos/kezplez-nx/releases) boot your console with the ipl.bin payload.
Once on the hekate menu, print your tsec fuses on your sd card (press power once all keys on the screen), next repeat and print your fuses info.
After you can load CFW.
After go into Hombrew Channel (select album), boot Kezplez and press "A" when the rainbow is on the scree. The apps will write a files named "keys.txt" on the root of your SD card.

2- (medium) - With your backup files and script locally on your PC.
Follow this guide : https://gbatemp.net/threads/how-to-get-switch-keys-for-hactool-xci-decrypting.506978/

Once you have the keys.txt file, rename it keys.dat and place the file in your 4NXCI directory and.... ENJOY !

Hope it will help you !

I converted then installed Layton KAtrielle Deluxe, it work fine.
I wonder if it's the same savefiule format as the 3ds version.

 

[Asia81]

@The-4n I got 1 feature for you, if you could take it as a request.
- Automatically rename the generated nsp file(s) according the the input .xci instead naming them with their TitleID.

When you convert a lot of xci in a batch process, as I'm currently doing :

4NXCI.exe Bayonetta2.xci
4NXCI.exe CrashBandicootNSaneTrilogy.xci
4NXCI.exe KirbyStarAllies.xci
4NXCI.exe MarioKart8Deluxe.xci
4NXCI.exe MyHeroAcademiaOnesJustice.xci
4NXCI.exe OctopathTraveler.xci
4NXCI.exe Splatoon2.xci
4NXCI.exe SuperMarioOdyssey.xci
4NXCI.exe ZeldaBreathOfTheWild.xci
pause

It could help to determin what game each nsp files are.

 

[naddel81]

Yes, that would be great!
