Good place to start.  Apparently no MMX but SIMD, this is way over my head

Good suggestion, fortunately I found that he (and most people doing
emulators, etc.) are using a private framework (CoreSurface) to draw to the
screen.  Unfortunately, private Frameworks means it's not usable from an
official SDK application (which I'm trying to do).  I'll cross my fingers
that this will change at some point, and hold my breath that apple drops the
NDA sooooon so I can see what others have done for workarounds.
