I have taken the time to inspect and understand the binary format of the SSF file. The SSF format stores its content (textures, geometry and animations) in the native platforms format. Therefore different approaches are required to view SSF formats from different platforms. This viewer only works with the Wii file format.
Below is an overview of small incremental I had to go through to decode the entire format.
Hacking a PS2 version of the game to understand the file format 
It looks like a paperbag on Scorpions head. 
First triangles, Kitana 
Textures and full meshes 
Skeletons and hierarchical transformation 
First attempt at stages. 
Lots of wrong transforms 
Getting better but textures are wrong 
Close but not correct. 
Now it looks good 
Putting it back together. 
Some other stages. 
That logo! 
More stages 
Lighting makes a big difference. 
Final stage of the game is actually pretty simple. 
Cool snake heads in reptiles lair. 
Red sector 
Blue sector. this could totally be a smoke replacement. 
Soul chamber! 
The real scorpion, but the file name is scorpion_alt.ssf wtf? 
Putting stuff together. 
More logos.
