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

Tangledeep patched to 5.1 with reNX v1.11

• ReiNX v2.1.1-- Error: "The software was closed because an error occurred" on ReiNX v2.11
  • Installed to SD card and NAND with Lithium 1.55 / Dev Menu / Tinfoil 883e3bd Error
• Atmosphere 0.8.7 w/sweet patches -- NSP freezes at startup once the lower right nintendo switch logo flips, have to restart switch
  • Installed to SD card and NAND with Lithium 1.55 / Dev Menu / Tinfoil 883e3bd Error

Final Fantasy VII patched to 5.1 with reNX v1.11

• ReiNX v2.1.1-- Error: "The software was closed because an error occurred" on ReiNX v2.11
  • Installed to SD card and NAND with Lithium 1.55 / Dev Menu / Tinfoil 883e3bd Error
• Atmosphere 0.8.7 w/sweet patches -- NSP freezes at startup once the lower right nintendo switch logo flips, have to restart switch
  • Installed to SD card and NAND with Lithium 1.55 / Dev Menu / Tinfoil 883e3bd Error

FYI Dev Menu installs on the previous version would have an error msg at the end saying the nsp was corrupt. on V1.11 it doesn't but still does not work

@Cyan Would it be helpful to add the SDK version of the game in question? XCI Explorer shows the version of a game!

Yes, I can add that information.
But, Is it really useful?

I mean, the end user doesn't have any relation to its own console's firmware version, and the SDK version used by the developer, does he?
how can the SDK version be useful to know if the game will be compatible or not? it would maybe require a new list of SDK version for each firmware to compare to.

If a game is using a specific SDK to build the game, can't it still use only old functions and IPC compatible with old firmwares?

that's just questions, if you think SDK is useful I can add it.

@Cyan That's right! Was only a thought!

anyone has the same error as me when i try the update from cuphead ill will get this error
Error: PFS0 is corrupt!

 

[KuranKu]

anyone has the same error as me when i try the update from cuphead ill will get this error
Error: PFS0 is corrupt!

its caused by Only one reason you trying instrall sdk7 game on sdk6 firmware.
solutions:
check SDK game/update version with XCI-EXplorer
if its SDK7 you must update firm to 7.0.1 if your below 7 ofcource.

otherwise if the SDK is below SDK7 it can be patched and maybe works

i have the 7.0.1 keys but i think the update is corrupt

I believe the update requires 8.0

 

[gizmomelb]

i have the 7.0.1 keys but i think the update is corrupt

yes there was a fixed version of the update released.

I get that error when I try repacking Smash Bros update 3.0.

Does this only appear empty for me or is there actually no content in that list?

 

[Kadji]

Looks like someone deleted all entrys from the wiki...

I get that error when I try repacking Smash Bros update 3.0.

Yeah I got that error on both of those updates as well. They also wouldn't install on OG Tinfoil 0.2.1, but installed just fine on Goldleaf 0.5 on OFW 7.0.1.

Worked perfectly fine for me on OG Tinfoil. Make sure you use USB install. My PC client was Aluminum Foil.

The update? Or the base game?

The base game installed just fine with OG Tinfoil/usb_install_pc.py script. I've been using that combo for months and haven't had a single issue. But both updates gave me an error when trying to install. Both USB install and just a regular install from SD.

Base game was already installed. I was mainly referring to the update, 3.0 to be exact, which worked flawlessly with USB install with Tinfoil and Aluminum Foil on my Windows 7 laptop.

Yeah my base game has been installed since the release date, but the update from yesterday wouldn't work.

The quote below suggests that maybe our NSPs were from a different source, so maybe that's where my issue lies.

seems to be a twofold issue from chatter on discord:

apparently some of hbg's updates are showing as having modified nca files because they removed deltas

and

goldleaf works with the broken update because goldleaf ignores the cert and uses it’s own, which is actually kind of bad


I dont have Cuphead or the update to test.. so can anyone verify either / both of the above comments?

I downloaded the raw untouched 2 GB one, not the one HBG uploaded, and patched it myself.

 

[The-4n]

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

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

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