In the debug player, the current CPU runs at ~2.5 MHz.  The original C64 
runs at 1 MHz, so currently we're ahead of the game.  This is, of 
course, minus the display code, which will slow things down a bit.

However, I was able get someone from Adobe to do performance tuning on 
the CPU core, and in the release player the code is a lot faster - the 
CPU runs somewhere between 6 and 7 MHz (I don't know the exact number, 
that's just what I was told).

So, in theory, we should be able to play games in "real-time", as long 
as we don't write slow display code :-)

If you're up to the challenge... ;-)  Let's see how fast this thing runs 
when all is said and done... hopefully we won't need to find workarounds 
because of performance reasons!
