cailei110

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:

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
Code:
*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
