SZS-Tool

Compress and decompress SZS files with the Yaz0 compression

Compatibility

FOR USE WITH NINTENDO 3DS GAMES ONLY. The .szs files from a Wii game will not work.

Future plans

• Add support for the following compressions (and an example of a game that uses that compression):
  • NARC (3DS)
    • Super Mario 3D Land
  • RARC (GameCube, Wii)
    • Super Mario Galaxy
  • SARC (Wii)
    • New Super Mario Bros. Wii
  • U8 (Wii U)
    • Mario Kart 8
• Detect what compression a file uses and if it's valid
• Add support for .arc, .carc, .narc and .sarc
• Rename the project to "Nintendo Archive Tool"
• Clean up UI & code

Compressing

• To compress, put all the files you wish to compress into a .zip file. This makes SZS Tool's job easier.
• Select the .zip file

Decompressing

• To decompress, select a supported file
• Next, choose a folder to export to

Downloads

Go to the Release pages.

Building

1. Ensure you have .NET Framework 4.5

FAQ

What about Wiimms SZS Tool?

The problem is that Wiimms SZS Tool (of which I did not make nor is it mine) is for Linux and Mac. It supports Windows, only with Cygwin. SZS Tool (this one) doesn't need Cygwin. Plus, Wiimms SZS Tool only works with .szs from Wii games, not GameCube, 3DS and Wii U games as this SZS Tool supports.
