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

Do you mind to share how you encrypt the MK11 updates? i got the master keys (v7.0.1), but when i try to encrypt using reNXpack the error shows: "Error: PFS0 is corrupt!"

Think I saw there was a bad update for mk11, make sure you've got a good version.

Hi all,
SSBU, repacked update 3.0 gets error during start, no error during repacking, how can I remove the update itself ?

TY

Update started working again as soon as I upgraded to firmware 7.0.1
Maybe something should be changed again in this software….

Yes! I'm playing FFX/X-2 on v6.2 after converted it by using reNXpack

There's no new key in 8.0.0
You don't have proper 7.0.0 keys

 

[The-4n]

I need your reports to update wiki (working or not working)
Make sure to use latest verison or reNXpack

 

[KnightMars]

reNXpack for MK11 update is fine, but its not working on Tinfoil when I want to install the nsp file

(Reinx 2.0 fw6.2)

 

[2Siralv]
