Re: the stop symbol...
Instead of 7-wide, make the cursor 9 wide.
Use the missile to give you the extra pixel you need. (8 player + 1 missile)
Then it is a simple-matter to use an 8-wide ball to provide the white area
you need.
Hope this helps

Subject: [stella] Jammed v0.2

attached to this is a slightly updated version. It now supports PAL with the
RIGHT DIFFICULTY switch (the PAL car is green now), and I did some code
optimizations. (still no sound and still ~200 bytes ROM and 30 bytes RAM

I'd like to use the ball to give the red stop cursor always a white
background. Unfortunately all cursors are 7 pixels wide (has to be an odd
number to make the up/down arrows look nice) and so the "hole" in the stop
cursor is 5 pixels wide. That means, I can only use a 4 pixel wide ball,
which I'd display, alternating between left and right aligned, inside the
"hole". This results in some quite noticable (in z26) flicker, when the
cursor is over a black background.

What do you think? Or do you have some better ideas how to handle that? (I
don't want to use the PF, because that would complicate everything a lot and
cost a lot of bytes too.)

Have fun!
