I suspect .SMM files found in Rogue Squadron 2's data are models.
Nothing much more i can say at the moment.

Here's a sample file for a TIE Fighter so maybe someone else can take a look(and maybe make a script to import it into 3DS Max or Noesis if it is indeed a model?)

Im not skilled enough in these kinda things to do it myself

your smm sample looks like texture data to me and being a Gamecube game could be one of nintendo texture formats.

funny, an animated parser! Format seems to be NINTEX_CMPR = 0x0E
, a little bit swizzled

need more samples to complete the script actual size is 1024 x 1024, had to scale it down to fit in attachment.
image data starts at 0x40, there is a footer too, not sure what it is.
i don't really see where is width and height info stored yet unless
is obfuscated in header or maybe stored in another file.
