Because awhile ago I already did somthing like this, It was in one of those high score threads and I claimed to have a high score of 4294967295. (That number is the exact maximum of four bytes, the amount of bytes that stores the score variable) of course usually that number would be negative (with a signed byte) so as the score went up that value would have the gained points added to it, and because of the way four signed bytes work it would eventually become negative (about at halfway.). JJ2 would still just add more to it, and after it became negative it would get closer to zero as points got added (but the actual four bytes would keep increasing) and at 4294967295 it would be -1 where if another point was added it would go back to zero. Just so you know, the way I got that screenshot of me with 4294967295 points was by using the value in the highscore menu instead as it was unsigned.
