Pac-Man Master Museum compiled/made by LackOfTrack (contributions from various other very talented devs). ROM available for free over at SMSPower.org. This is a port very close the original arcade Pac-Man game from 1980.
Link to SMS Power: smspower.org/Homebrew/Pac-ManMasterMuseum-SMS
Notes:
An accuracy-focused conversion of Pac-Man and Ms. Pac-Man for the Sega Master System.
Features
High Accuracy: The games play just like the originals.
The Ghost AI is faithfully replicated. Patterns for the originals can be executed here as well. (Not 100% verified)
Sound effects and music are as accurate as possible given the limitations of the SN76489, the Master System's sound chip.
Game Selection: Choose between Pac-Man and Ms. Pac-Man by pressing left or right on the title screen.
Press Button 2 to play the Plus variants.
Customizable: Difficulty, life count, bonus life, and other settings are fully configurable in the options menu.
The popular speed-up mode can be toggled in the options menu as well.
Two Graphic Styles:
Smooth – Adds extra detail and color utilizing the Master System’s superior graphical capabilities.
Arcade – Faithfully replicates the original arcade look as close as possible.
1–2 Player Support
About the Project
This started as a personal project to learn Z80 assembly. My long-term goal was to create a Pac-Man Collection featuring Pac-Man, Ms. Pac-Man, and Pac-Man Plus, inspired by Opcode Games’ Colecovision release.
My key inspirations for this project were:
Pac-Man Collection by Opcode Games
Ms. Pac-Man Classic by xfixium
Pac-Man Emulator by Simon Owen
Pac-Man by masonicGIT
I hope this code is useful for anyone interested in learning Z80 assembly or exploring how Pac-Man works internally.

This project wouldn't nearly be as polished without the help of these people:
