+
+Libble Rabble (c) 1983 Namco
+Toypop (c) 1986 Namco
+
+driver by Edgardo E. Contini Salvan (pag2806@iperbole.bologna.it)
+
+6809 main CPU,
+6809 sound and
+68000 to create the background image.
+
+Libble Rabble and Toypop run on the same board, but the memory map is subtly
+different.
+
+Notes:
+------
+- Libble Rabble Easter egg:
+ - enter service mode
+ - turn off the service mode switch, and turn it on again quickly to remain
+ on the monitor test grid
+ - Enter the following sequence using the right joystick:
+ 9xU 2xR 9xD 2xL
+ (c) 1983 NAMCO LTD. will appear on the screen.
+
+
+TODO:
+- I haven't found any Easter egg in Toy Pop. Maybe they had stopped inserting
+ them by that time.
