am_mg3: MAME ROM Information.


Multi Game III (c) 2000 Amatic Industries.


Game's ROM.

MAME Info:

0.134u1 [Roberto Fresca, Team Europe]


- 0.145u8: Simplified gfx rom loading. Small mods for am_mg3, they won't boot tho. Color bitplane fix for am_mg3 [Angelo Salese]. Fixed gfx1 rom loading. Added YM3812 (4MHz) sound and mono Speaker. Added dipswitches 'DIP1', 'DIP2', 'Coin 1 (Muenzen 1)', 'Coin 2 (Muenzen 2)', 'Jackpot', 'Fruechtebonus', 'DIP7' and 'BH'.

- 0.142u3: Changed palettesize to 65536 colors.

- 0.134u1: Roberto Fresca and Team Europe added 'Multi Game III (V.Ger 3.5)' (Amatic Trading GMBH 2000). New driver for Amatic encryped gambling hardware. This system is based on a custom CPU. Graphics are decoded but only 2 bitplanes hooked. All the needed devices are in the driver, but commented out till can properly decrypt the program ROMs and identify the CPU. About the encryption scheme, see the driver notes about my findings [Roberto Fresca].
