You deadass just made the score overflow from positive to negative, then go back to positive, and then overflow to negative a _second time._ What a legend.

i always wondered why the score display in this game suffers the 32-bit integer limit, while it worked perfectly fine in touhou 7, 8, 10, and 11

25:00 look at the score, integer overflow! (from 2147483647 onwards it starts going down)

So 2147483647 is one more than 2^31... So as someone who knows nothing about programming, I'm guessing that means that the integer value for the score had a limit of 32 bits? Am I understanding that correctly?

@@CopiousDoinksLLC yes: 01111111 11111111 11111111 11111111 in binary is 2147483647, and 10000000 00000000 00000000 00000000 in binary is -2147483648 with the way we represent 32-bit signed integers. We do this because then addition on normal scales works properly: 11111111 11111111 11111111 11111111 + (-1) 00000000 00000000 00000000 00000001 = (1) 00000000 00000000 00000000 00000000 (0) which uses unsigned integer overflow as a feature that allows us to represent negatives. Overflows with signed integers happen when a carry ends up reaching the sign bit and stops there.

Your score was so high, you managed to integer overflow the score *TWICE*.

Awalys If we're being technical here, he did it three times. Once made it so his score looked like it was going down, second time made it so his score rose again, and the third time made it so it decreased again. This is absolutely insane. XD

As far as I know, overflowing something is tricking the system into going from the highest possible number to the lowest possible number. In this instance, the highest possible number would be 2,147,483,648, while the lowest possible number would be -2,147,483,647. That is the total range of a signed 32-bit system, which is the scoring range for Touhou 12 (I don't think it's possible to obtain negative score in UFO other than overflowing, but if it is I'm sure it's extremely unlikely). -2,147,483,647 to 0 is not in itself the whole set of integers, nor is 0 to 2,147,483,648, but -2,147,483,647 to 2,147,483,648. They went so far in score that they "technically" overflowed about 1.5 times, since the total possible amount of numbers in a signed 32-bit system is 4,294,967,295, give or take a few. 6,624,561,400 - 4,294,967,295 = 2,329,594,105, about ~200M points above 1.5 times the total amount of numbers a signed 32-system can hold. But if we're being real here, it's still fucking insane. To make the game not only enter the negatives once, but TWICE in a run, not to mention trying this run 65,721 fucking times... jfc. (My math may be a few numbers off here and there. Just my two-sense, even if 7 months late...)

Because score type is "32 bits signed integer" and when the score over the max (=2147483647),the score overflow and it become -2147483648. so the score looks like decreasing when it is minus. sorry i'm Japanese and i know my English isn't good.
