Tool-assisted superplay (TAS) of Quester Arcade 26,349,440 points

My score should have been 1,549,440 if it hadn't been for a bug.

NOTES:
-The game was produced by Toru Iwatani, known as the creator of Pac-Man. It was created as a response to Taito's 1986 arcade title Arkanoid, which helped revive the block breaker genre and inspire waves of its own clone games. (wikipedia)

-The choice of the angle the ball bounces off the paddle is less than I would have liked, which is why some levels took so long to complete

-The game gave me 255 lives after killing the final boss.
I ran MAME in debug mode to monitor the memory location of lives. The 255 lives appear in memory when the 2nd block of the boss is broken.
I was thinking that on stage 32 there was maybe too much balls at the same time on the screen (11), so I redid the end of the TAS by keeping only 3 balls on the stage 32 and I still received 255 lives.
Even if I lose a life between the 1st and 2nd block of the boss, I still receive 255 lives when the 2nd block breaks.
So, I don't have a good explanation on what is causing this bug.

At the end you get 100,000 points for each life, I should have gotten 700,000 bonus points instead of 25,500,000, so my real score is 1,549,440 points.
