A few quick notes:

1. It is very important to keep the level files with the main program
2. I actually missed a delay loop, which you will encounter if you
   ever win the game.  As if!
3. The note file doesn't work quite right in 20MHz mode (I assumed
   1MHz cycles in one place), and will flicker.  Too bad.  Maybe
   someone should SCPU fix it :).
