reNXpack is a tool for repacking Nintendo Switch nsps to work on lower firmwares

Features:

• Repack games, updates and dlcs with lowest encryption keys
• Convert titlekey encrypted ncas to standard encrypted ncas
• Patch required firmware version and required application version to zero
• Support nsps containing multiple games, updates and dlcs

Some nsps may not work on lower firmwares due to lack of required IPCs
You can check games compatibility here:
https://wiki.gbatemp.net/wiki/Switch_games_firmware_requirement

Usage:
You should load your keyset file with -k or --keyset option followed by a path to it or place your keyset file with "keys.dat" filename in the same folder as reNXpack
By default, Created nsp files are located in the same folder as reNXpack with 'titleid_reNXpack.nsp' filename
You can change output directory with -o, --outdir option
reNXpack creates "renxpack_extracted_nsp" folder as a temp directory, It deletes the directory content before and after conversion
If you use -t, --tempdir option to choose a temporary directory, Make sure it's an empty directory and it's not the same as output directory otherwise reNXpack deletes it

*nix: ./renxpack [options...] <path_to_file.nsp>
Windows: .\renxpack.exe [options...] <path_to_file.nsp>
 
Options:
-k, --keyset             Set keyset filepath, default filepath is ./keys.dat
-h, --help               Display usage
-t, --tempdir            Set temporary directory path
-o, --outdir             Set output directory path

i got MK11 with the update V1.0.2 in one singel XCI file
i see it on SXOS but when i wanne start the game it`s say gamecard could read?

 

[2Siralv]

I have an idea or question can you add so that if it finds any brick code or unsigned code that seems it shouldnt be thier and get removed and let us know in the log so ppl can let others know whrre that nsp came from and it had bad code to brick

When using this for DLC (only tried with small under 200kb nsp dlc) the Switch says upon trying to start the game "Unplayable downloadable content was found" but it's still playable if you press Start Software.

Is all the DLC like this after repacking or just the small unlock ones?

This is a known issue for standard crypto dlcs (download type, not gamecard type)
DLCs work fine. That message is not important

Yeah just a minor annoyance but no big deal still works.
Thought i would report it anyway.

What does this do that 4NXCI doesnt already do?

 

[wicksand420]

What does this do that 4NXCI doesnt already do?

It repacks a game that lets say requires 7.0.1 so it can be used with lower fw versions, it encrypts it with lower keys I believe.

 

[Rune]

It repacks a game that lets say requires 7.0.1 so it can be used with lower fw versions, it encrypts it with lower keys I believe.

But 4NXCI does that too. So why would you use this over that?

 

[Philliyxx]

But 4NXCI does that too. So why would you use this over that?

Well there are multiple apps in the scene, everyone is free to develop what he/she wants
We have hactool and hactoolnet, dz and goldleaf, edizon and checkpoint, ....

And i don't follow most of the scene apps, I didn't know such an app exist

But i've already mentioned the features, I try to make my apps easy to use, usually one click, and currently they are only apps that doesn't require acid sig patches (change acid public key and sign nca sig 2)
So feel free to use every app you want

 

[stick267]

4nxci converts XCI files to NSP. That's not what reNXpack does.

 

[Rune]

4nxci converts XCI files to NSP. That's not what reNXpack does.

4NXCI also converts NSP to XCI, or XCI to XCI, or whatever you like. And it can also take an NSP, re-encrypt it with lower keys, and repack it in a new NSP (or XCI). Which is exactly what reNXpack does.
And both of these tools are made by the same person as well.

Which is why I'm asking. Is reNXpack just a lite version of the same tool with one specific purpose (as opposed to the multi-tool that 4NXCI is)? So am I missing something?

I'm unaware of all of those features you mentioned. They're not even listed in the github. Are you sure you're talking about 4nxci?

Ok, I may have mistaken this for something else
I dont even know where I got the tool I'm using anymore.


EDIT
Just realised I'm actually talking about NSC Builder. Sorry.

No worries. 4nxci is great because it's simple and straight to the point so I knew you were thinking of something else.

If someone wants to edit the wiki the below games all worked when repacked to 5.1 keys. Not sure about some of the FW bypass requirements as I am not on higher FW to check. Also the Tales of Vesperia DLC's all installed and work on 5.1 I did not find their title ID's

Can you please use the latest version of reNXpack, It tells you the required system version and keygeneration, if you tell me those values i can fill the wiki table

 

[nraudigy2]

Confirm: Mortal Kombat 11 [0] & [v65536] works after standard encryption with 6.2 (SDK 6.5.x)

--------------------- MERGED ---------------------------


Cuphead Update doesnt show anything with XCI-Explorer. I get the same massage with reNXpack, tested different sources.

You had to choose standard encryption in Tinfoil?

 

[DocKlokMan]

Deltafragments are totally useless
reNXpack deletes them, some title installers ignore them too

Can you talk a little more about DeltaFragments? Why are they listed in the CNMT along with the Control, Meta, Program, and LegalInfo NCAs if they're not used for anything? Why do some games fail to launch when updates not containing DeltaFragments are installed?

Tried repacking MK11... v0 (6.8gb) was successfully repacked and working but its game modes are limited indicating that it does require the update file.

When I tried repacking the update file, v131072 (16.9gb), I get this weird error:
----------------------------------------------------------------------------------------------------------------
reNXpack execution started. Please wait...

reNXpack v1.16 by The-4n

Loading 'D:\Downloads\Mortal Kombat 11 [NSP]\renxpack-v1.16_GUI\keys.dat' keyset file

Saving 5885aea238298030c4ac3681e036dc92.cnmt.nca to renxpack_extracted_nsp\5885aea238298030c4ac3681e036dc92.cnmt.nca...
Unknown meta type! Are keys correct?
----------------------------------------------------------------------------------------------------------------

If I try to install the update without repacking it, it installs, but then the game icon shows as a spinning wheel (as if trying to load something) and nothing else happens. I can't even remove the update or the original app which forces me to restore my entire switch from a backup.

I downloaded both files from two different sources, and the same thing happens.

Using FW6.2.0, SX Pro 2.6.1, Emunand

Would appreciate any help in figuring out why this is happening.

Thanks.

the game requires a specific IPC added in a later firmware, the MK11 update will not work on fw6.2 , even if encrypted using a compatible encryption key.
