I wish my memory was that good
I mostly used pictures of the cabinet that were on the namco website. And I took some pictures of the cabinet myself (for the warning label).
Your work looks spot-on. Kudos to you for attempting this project, especially the game design aspect. I can't imagine the hours of programming it will take to recreate this game.
That gets me to thinking about Toru Iwatani's design of the original Pac-Man, particularly the ghost AI:
"When you play the game, it might seem as if the four ghosts are actively chasing you ... Instead, it’s only Blinky, the red ghost, who doggedly pursues you throughout the game. Pinky, the pink ghost (naturally), simply wants to position itself at a point that’s 32 pixels in front of Pac-Man’s mouth. The blue ghost, Inky, is seeking to position itself at a similar fixed spot. And Clyde, the orange ghost, moves completely at random."
