Libble Rabble (c) 1983 Namco
Toypop (c) 1986 Namco
"Universal System 16" Hardware (c) 1983/1986 Namco
Namco "Universal System 16" Hardware
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:
- PAL is presumably inverted with address bit 11 (0x800) for 0x6000-0x7fff area
between Libble Rabble and Toy Pop.
- Proper sprite DMA.
