4NXCI is a software developed for converting XCI file (cartridge dump) to NSP file (Eshop dump). Works on almost every XCI file for most popular games.
Latest build and its information can be found on Github
Note: You need to search up latest version for Mac on Google. Or use this page on Github.
Create a new folder. It should have
- 4nxci.exe (4nxci, for Mac)
- prod.keys (rename it to keys.dat)
- .xci game file(s) that you want to convert to .nsp
Open cmd.exe (windows) or terminal (mac) and cd to this folder. Depending on your OS, type in:
.\4nxci.exe <path_to_file.xci> (windows)
./4nxci <path_to_file.xci> (mac, *nix)
Unlike Python, the path should be in full so I recommend just type in first part, a space, then drag .xci file into the command window.
The conversion will start after a few error lines. Those don’t matter and can be ignored.
Put the newly made .nsp file into your SD and test it using Tinfoil.
