The DC has configurable system timers, to profile a specific section I
check the time at two points and subtract, then add that delta to a global
counter.  Also, I do this at emulation start and end time, then divide it
by total # of frames for an accurate fps count.

At one point I added FPS calculation to the x86 version in my copy of the
tree.  I doubt I have the code any more, but it's trivial to do, since you
can use gettimeofday() instead of custom timer code.

I will probably make an initial release once I achieve 60 fps consistently.
In the meantime, there are other released NES emus for the DC (they may run
slow too, though).
