You're using 1102 bytes.
Before you do your org $FF00 add the line...

	echo "***", (*-Start), " BYTES OF ROM USED"

and before you do org $FFFC add ...

	echo "***", (*-WingUpGraphic), " BYTES OF ROM USED"

The literals between the "" are just there for you to quickly identify
the verbiage. The real work is done in (*-label). This calculates the
number of bytes used between the current position and the label
specified. Now when you assemble your program look at the results from
DASM (or the list file) and you'll see the number of bytes used between
those labels. Now you just have to add those values and see how many
bytes are used :)

Use Z26's trace option and look at the trace file. It will tell you
everything you want to know about what's happening during program

I'd like a little more time before the ball appears to give me some time
to react. Also a slower speed like pong would be nice :)

Also, are you looking for optimization suggestions too? There are some
opportunities to free up some more bytes in your code. Then you could
possibly enter it into the 1K game competition.

I think it should just go back to the title screen. No options should
change. Only let the options change when the title screen is present.

I like the one you have. It looks sort of like the one used in Video
