The above code has problem. Ball often passes through a block then goes to out of screen.
I don't know this is cheat related bug or emulation problem (this game is "not working" status).
Other addresses are...
- 206f : credit
- 2055 : life
- 2052 : ball x-position
- 2053 : ball y-position
- 2062 : flag for ball rise or fall
- 2056 : score (2bytes BCD)
- 207a : top score (2bytes BCD)

- "keep a ball" : Changed status as test.
- "ball speed" : Added new as test.
There games are marked as "machine not working". The ball doesn't appear in the field after start the game so that I can't verify the cheat codes.
