  Sorry, you are wrong.  I own  three SNES games that
use the SFX chip:
 Starfox, Stunt Race FX and Yoshi's Island (SFX chip used for sprite
 rotation and 3D objects, such as doors that fell towards the screen).  
Cool.  I thought there were only two as well.  Glad to be corrected, then.
I don't remember Stunt Race FX, but I sure loved Starfox.
  The Megadrive had a few games too, with the SVP (Sega
Virtua Processor)
 chip: Virtua Fighter (I think?), Virtua Racing (definately) and Vectorman (I
 think?). 
Oh I never heard about that one.  I believe I have one of those titles for
the Sega 32X, too.  However, it probably had enough grunt to play it as-is.
I'm not sure if the 32X had any 3D hardware.
