Say Roger,

This is looking great!  Keep us posted on the progress.

I've never done any game programming before and have a question.  Did you
start with the graphics first, or with the logic of the rules of the game?
I could see getting blocked on either if you aren't careful.

Oh, and my Mary and the Bees high score is 1113.

Check out the new screenshots of the basic layout of the Jeweled game 
I'm almost done with.  Clicking on the thumbnail will show a bigger shot.

The new game is coming along well.  I've got the page flipping down 
which uses the Bjork-suggested method of having 3 32k screens.  One 
is the backdrop screen, and the other two are alternated to allow 
smooth flicker-free animation.  The sprites are moving pretty fast 
considering how many there are.  Count'em... there's 64!    I've got 
their delta movements set to travel in a demo fashion so I can see 
the speed imrovements while I optimize the code even more.  It's not 
typical code, though.  Loops are reduced or eliminated, values are 
precalculated wherever possible, stack-blasting is used to save lots 
of cycles, and ofcourse the ADDD # instruction is used instead of ORA 
# and ORB # in the mask/overlay code.
