FNU - Nintendo NSP/XCI Unpacker

3 Attachment(s)

I was into repacking some nintendo games the other day so i decided to write a program to handle some stuff automatically!!

here is FNU - aka Fox Nintendo Utility

you will need your own set of keys to work.

Q) why to use this??
A) because in default state nintendo NCAs aren't repackable, the main nca is encrypted thus making repacking impossible. with this tool you can decrypt main NCA enabling repack.

sorry to necrobump
has there been any update regarding this ? i think i mightve found a way to losslessly decrypt and encrypt a nsp file.
