+
+ Pacman - 25th Anniversary Edition
+ Ms.Pac-Man/Galaga - 20th Anniversary Class of 1981 Reunion
+
+ driver by Nicola Salmoria
+
+ Notes for Ms.Pac-Man/Galaga - 20th Anniversary:
+ * There are four start buttons: the first two are for Ms. Pac-Man, the other two
+ are for Galaga.
+ * To play Pac-Man instead of Ms. Pac-Man, insert coins then enter the following
+ sequence: U U U D D D L R L R L. A sound will play and the ghost will change
+ from red to pink. Then press the start button for Ms. Pac-Man.
+ * To toggle the built-in speedup, insert coins then enter the following sequence:
+ L R L R U U U Fire. A sound will play if you did it correctly. This will toggle
+ the speed in both Ms Pacman & Pacman as well as provide a "Fast Shot" in Galaga
+ * Writes to the Z180 ASCI port:
+ MS PAC-MAN/GALAGA
+ arcade video system
+ version 1.01
+ (c) 2000 Cosmodog, Ltd.
+ >
+ and it listens for incoming characters.
+
+ Notes for Pacman - 25th Anniversary:
+ * Pacman 25th Anniversary is a program update which allows the player to choose the
+ game they want to play. You highlight the wanted game and then press the 1 or 2
+ player start button to start the game.
+ * There is a minor board difference that the program code can detect through the Z80
+ ports to prevent ROM swaps to upgrade Ms. Pac-Man/Galaga - 20th Anniversary Class
+ of 1981 Reunion boards.
+ * The above listed joystick maneuver for the built-in speed up still works.
+ * The above listed joystick maneuver to enable Pac-Man will still play a tone, but
+ the effect (if any) is unknown.
+
+ * CPU is a Z8S18020VSC (20MHz part), OSC is 73.728MHz
+
+ Note: The "correct" size of the roms are 27C020 for the program rom and 27C256 for the
+ graphics rom. However genuine boards have been found with larger roms containing
+ the same data with the extra rom space blanked out.
+
+ Known issues/to-do's:
+ * Starfield is not 100% accurate
+ * Check the ASCI interface, there probably is fully working debug code.
+ * The timed interrupt is a kludge; it is supposed to be generated internally by
+ the Z180, but the cpu core doesn't support that yet.
+ * Is the clock divide 3 or 4?
