+Pac-Man Emulator for SAM Coupe (v1.2)
+-------------------------------------
+
+The Pac-Man ROMs cannot be supplied 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
+
+Copy them to the same directory as this file, then run make.bat (Windows).
+Under Mac/Linux/Un*x, use make to build the final pacemu.dsk disk image,
+or combine manually using:
+
+  cat disk.base pacman.6[efhj] > pacemu.dsk
+
+Enjoy!
+
+---
+
+Version 1.2 (2012/01/17)
+- Improved sprite draw/restore/clip code for extra speed
+- Faster tile updates when no sprites are visible
+- Added boot-time selection of Hard difficulty
+- Added SAM joystick 1 and QAOP input methods
+- Improved control handling, favouring latest direction change
+- Skip RAM-check for faster startup
+- Easier method to add ROMs to form final disk image
+
+
+Version 1.1a (2004/10/09)
+- Added build-time control of tile strip count, for Mayhem accelerator
+
+Version 1.1 (2004/10/01)
+- Changed code from Assembly Studio 8x to pyz80 (Comet) format
+- Simplified build setup, moving a few things around
