Tool-assisted speedrun (TAS) of Space Invaders arcade 10,000 points in 5:11

Goal of the TAS:
-Get 10,000 points as quickly as possible.
-shoot enemies constantly (not waiting for the saucer)

Notes:
-After examining the final video I see some places that can be improved a bit, but I evaluate that only 3-4 sec can be gain. I do not think it is possible to go under 5:00.
-Now the question is: Is it faster to shoot as many saucer at 300 points as possible instead of shooting enemies? The answer is NO. View my other video on Space Invaders.
-At 00:15 you can see the hidden message: "TAITO COP" (with no "R" because they ran out of space in the ROM)
To trigger the display of that message, you have to press simultaneously 2 sequences of buttons:
1- 2 start, fire, left, right
2- 1 start, fire, left
During the demo, while the game is playing alone (not the title screen),
the buttons must be pressed (and released) on the same frame, but you can stay pressed or released as long as you want.
Do not try that in Mame it will probably not work (except in a TAS).
-As you probably know, the saucer give a mystery bonus that is not a big mystery anymore.
The sequence of score is:
50, 50,100,150,100,100, 50,300,100,100,100, 50,150,100,100
The value of the bonus is taken from this table, but change for the next value each time the player shoot a bullet.
The saucer appear every 1536 ($600) frames, so every 25.6 sec.
The timer reset at the start of every wave except for wave 1 where the timer wait for the invaders to drop down a row before starting.
