User guide

In general:

• All files are always created in the SAK folder.
• Only XCI + NSP files >= 4GB are accepted for splitting.
• It doesn't make sense to split files < 4GB.

For patching XCI to lower firmware:

• keys.dat/prod.keys is required.
• File must be as XCI.

For splitting XCI:

• XCI can be split full size or trimmed.
• Trimmed means that the empty space at the end will be removed.
• This will saves you a lot of space for the XCI image.
• The new file name will be append with "_splitted".
• Can also be split directly to the SD card over the USB card reader.

Merging XCI:

• Extensions.xc0 and .xci.00 are accepted.

Updating XCI with game updates:

• Require your dumped game as XCI, the latest update as NSP/NSZ optionally your dumped DLC's as NSP.

Converting XCI to NSP:

• keys.dat/prod.keys is required.

Compressing XCI to XCZ:

• keys.dat/prod.keys is required.

Decompressing XCZ to XCI:

• keys.dat/prod.keys is required.

Extracting firmware:

• keys.dat/prod.keys is required.
• File must be in XCI.

Patching NSP to lower firmware:

• keys.dat/prod.keys is required.
• File must be in NSP.

Splitting NSP:

• The split files are stored in a folder with a sequential number.
• As reference for the folder name, the current NSP file name is taken and added with "splitted".
• Can now be split directly to the SD card over USB card reader.
• The archive bit is set automatically.

Merging NSP:

• Your splitted NSP only select the (00) file.
• All others are automatically selected.

Updating NSP with game updates:

• Require your dumped game as NSP, the latest update as NSP/NSZ optionally your dumped DLC's as NSP.

Converting NSP to XCI:

• Only games are supported.
• keys.dat/prod.keys is required.

Compressing NSP to NSZ:

• keys.dat/prod.keys is required.

Decompressing NSZ to NSP:

• keys.dat/prod.keys is required.

Extracting saves:

• keys.dat/prod.keys is required.
• Your save folder from the user partition (HacDiskMount or via Homebrew Tool).

NGO forwarder:

• keys.dat/prod.keys is required.
• Icon as jpg/jpeg with resolution 256x256.
• To use your own startup logos, create a folder named "custom" in the SAK.exe directory.
• Place the files as "NintendoLogo.png" and "StartupMovie.gif" here.
• For example look at "bin" dir.

FAT32 format:

• If you get an error while formatting the SD card ("Failed to open device") make sure nothing is accessing the SD card. Even having the Windows Explorer open can cause this issue.
• Here's how it should work:
  • Start FAT32 Format and then insert the SD card into the card reader.
  • Select the SD card and click on the "Format" button.
