Using a novel approach for computing real-time game strategy, engineers have developed an artificial Ms. Pac-Man game showing control vector sign conventions used in the study. Special thanks to Eric Akeson for his help and patience in tracking down some particularly infuriating bugs over the past few months.A screen capture of the Ms. I will attempt to address the NTSC flickering in a future update. The game does function on NTSC machines but I recommend running on PAL if possible to avoid flickering. This probably won't play 100% like the arcade game because a lot of its behaviour depends on the tile data layout of the arcade ROM, but then again, only a handful of people in the world are good enough to reach it!įor more details on ghost AI, speeds, timers, and general strategy see the dossier.
I also included the famous kill screen that occurs when completing level 255. I even went as far as including an 8K lookup table that returns exactly the same sequence of random numbers as the arcade machine, which is often one area where conversions diverge as ghosts in 'frightened' mode make 'random' turns, but always in the same sequence. It only takes a pixel difference two minutes into a frame-perfect pattern to throw things off, but of course you need to be a great player to play the patterns in the first place and notice the difference.for us casual players it should play near-identically to the arcade. This initial version might not be quite there, but I have been working with some Pacman experts, including some of the few people in the world to play a perfect game and will hopefully continue to do so until the goal is reached.
MS PACMAN GAME NOT LOADING CODE
On PAL I fake 60fps by running the game loop twice every 5th frame, while skipping the sound code every 6th frame on NTSC. Therefore there would be no adjustments needed to the logic behind the movement of Pacman or the ghosts.
In order to achieve my ultimate aim that a player who can play a perfect game on the arcade can also do so on the C64, it was clear the map would need to scroll so that it would be exactly the same as the arcade. There have been some good ports and clones on the C64, and of course there is the definitive Ms Pacman conversion in the shape of Lady Pac, but the level of detail in the dossier gave me everything I needed to get as close as possible to the original arcade game. I was inspired to attempt to create a really accurate port of Pacman after reading The Pacman Dossier by Jamey Pittman.
Your kind donations allow me to occasionally take my wife out for lunch in lieu of the hundreds of hours a year spent on C64 development, and are greatly appreciated! I cannot accept payment for this game but if you'd like to support my game development in general you can leave a tip here.
