nxconvert – Convert XCI/NSP to DXCI/DNSP (for nxemu)

klgplyyiohksiowt · Mar 23, 2026

Hey everyone,

I’ve vibe coded a tool that converts Nintendo Switch XCI and NSP files into fully decrypted DXCI/DNCA format so that they can be used on nxemu

usage:
---------
nxconvert <input_file> <output_dir> <keys.txt>

Example:
nxconvert game.xci output/ prod.keys

Source code

Binary:

You can tell it was. Here:

C++:

// Namespace alias for filesystem
namespace fs = std::filesystem;

AI (correctly) assumes the people using it to vibe code don't have a clue. No real C++ dev would comment something like that because it's common sense?

outside of the AI styling, no one else has made a tool i can find that does this, so it is still fairly novel

What's this!?

What do you mean the Github Account "klgplyyiohksiowt" has submitted a sketchy file!?

What has this world devolved into?!

Is there no decency amongst friends?!

I'm flabbergasted.

xD

Kekekeke!

Stay safe kids :

Also, for the love of God, can someone have a real go at this? Thanks :
