What is a SZS file?

A .SZS file is a compressed game archive used by Nintendo. Game developers use this format for the GameCube, Wii, and Nintendo Switch consoles. The file contains 3D models, textures, animations, and level layouts. The data uses Yaz0 compression to save storage space.

How to open SZS files?

Standard archive tools cannot open .SZS files. You need specialized modding software like Switch Toolbox or Wexos's Toolbox. Game modders also use command-line utilities like Wiimms SZS Tools to extract and pack these files.
