Pac-Man Emulator for SAM Coupé v1.4


This program emulates the Pac-Man hardware environment, allowing the arcade Pac-Man ROMs to run (almost) unmodified on the SAM Coupé. The Z80 code is executed natively, but the sprite and tile display hardware is emulated. The sound and input are mapped to the closest SAM equivalents.


The Pac-Man ROMs cannot be distributed with this program, so you must provide your own copies of the following files (from the Midway ROM set):

  pacman.6e pacman.6f pacman.6h pacman.6j


The pacemu.dsk disk image is created by combining the supplied disk image fragments with the Pac-Man ROM images:

  1. Copy the Pac-Man ROM images (detailed above) to the pacemu directory.
  2. Windows users: run make.bat. Linux/Mac/Unix users run make.
  3. Open the .dsk image with a SAM emulator, such as SimCoupe.


Key Action
1 1 Player Start
2 2 Player Start
3 Insert Coin
F9 Hard difficulty (hold during ROM boot)
Cursor Keys Joystick Control
Q/A/O/P Joystick Control
SAM Joystick 1 Joystick Control

To check the difficulty setting, watch the cyan ghost at the start of the game. On Hard it exits the ghost box immediately, on Normal it waits around 6 seconds.

Build From Source

You may also build the emulator from source code, which requires a few extra tools.


Ensure and are in your path, then run make.bat (Windows) or make (Linux/Mac/Unix) to generate pacemu.dsk.
