Did the original Pac-Man have a highscore list? If so, how many scores could be saved?
I could only find an image showing the highscore at the top of the game screen.
If this commented Pacman disassembly is accurate, it appears that only one high score is maintained for the lifetime of the game. I believe the comment below (from the aforementioned disassembly) indicates the address range of the high score value:
;; 4e88-4e8b High score
The Ms. Pac-Man disassembly also seems to follow the same pattern:
; SCORE AABBCC ; $4e80 P1 CC ; $4e81 P1 BB ; $4e82 P1 AA ; $4e83 ; ; $4e84 P2 CC ; $4e85 P2 BB ; $4e86 P2 AA ; $4e87 ; ; $4e88 TOP CC ; $4e89 TOP BB ; $4e8a TOP AA
One may wonder: are these two commented disassembly print-outs accurate and legitimate? It's hard to say for sure, but a few Pacman-oriented websites cite them, this article being chief among them: Splitting Apart the Split Screen.
No, it does not. The game's attract sequence has three parts:
No high-score list is ever shown. In addition, no capability for initials entry exists. The current highest score achieved is recorded, but that is the extent of it.
Well, first of all, the screenshot you show is of Ms. Pac-Man and not Pac-Man. But to answer your question, no - the highest score is the only one shown, and you don't even get to enter your name for that.
