@@Prog61 If I had to guess, part of the code for defeating the final boss wrote the value of -1 to your life counter. Since your lives are never meant to go negative, and probably can't go above 9 under normal circumstances, the number of lives remaining is stored as an unsigned integer, 1 byte in length. When a -1 is written to the counter, it tries to go below zero, can't (unsigned integer, after all), and instead wraps around to the highest value possible for a one-byte integer starting at 0, which is 255. It'd probably be a simple bug to fix, but likely wasn't caught in playtesting because I doubt many of the testers - if they had any at all, they only list a single hardware tester in the credits - could get to the end of the game.
I experienced this on a real machine, but I didn't keep a lot of balls at that time. I don't know the cause. In this video, there are 12 balls on stage 16, and I don't think the max of the balls is 10.
There is no doubt that I split the ball in the final stage when I experienced it, so I think there is probably one of the factors. (It was clear with 1 coin, but there were many mistakes.)
You're probably right, the number of balls on the screen is probably not the reason I got 255 lives at the end. 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 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 of the cause of this bug. Thanks for your comments.
Is there not a faster way to complete levels than this? I'm not talking about MULTIBALL levels where the sheer number of balls clear everything, I mean the levels where you only use 1 ball for a majority. It seems terribly ineffecient to only hit one or two blocks as opposed to getting your ball bouncing forever in the top half. Is it a matter of bounce angles?

RUclips’s algorithms never cease to surprise me
This is probably the most interesting Arkaclone I've seen yet.
What a huge score!
As I explained in the comments, the final score should have been 1,549,440 points, but a glitch at the end gave me 255 lives at 100,000 points each.

This appeared in my recommendeds, but I do not regret it
I didn’t know this game had an ending!
man this is crazy! thanks Prog61!!!
Awesome TAS!
This must have taken a long time. Very impressive
4:30 A very special appearance by Pacman!
Awesome. The music is cool too
Impressive! Could you do Ghoul Panic next?
It Makes A Musical To Me!
19:28 if you want to see balls getting stuck to walls and forgetting physics for brief moments
3:34 A very special appearance of GalBoss!
Huh, never knew about this before. So it’s like Breakout?
Yes, It was created as a response to Taito's 1986 arcade title Arkanoid. (Wikipedia)
@@Prog61 Interesting.
Taito just called, they'd like they Arkanoid back! (I guess if you went back far enough, Atari just called, they'd like their Breakout back).

8:29 Special Flag
where did you found that game, and I haven't seen the Road Runner TAS, so win will the Road Runner TAS start?
I did not know this game before seeing it in MAME.
Road Runner is near the top of my list. I will work on it soon.
