/*************************************************************************** Centipede, Millipede, Missile Command, Let's Go Bowling "Multipede" (c) 1980-2 / 2002 - Infogrames / CosmoDog preliminary driver by Angelo Salese Earlier revisions of this cabinet did not include the bowling game. TODO: - program banking; - finish video emulation; - inputs; - sound; - change the CPU when a G658C02 core will be available; - driver probably needs rewriting, at least the i/o part; Probably on the CPLD (CY39100V208B) - Quoted from Cosmodog's website: "Instead, we used a programmable chip that we could reconfigure very quickly while the game is running. So, during that 1/8th of a second or so when the screen goes black while it switches games, it's actually reloading the hardware with a whole new design to run the next game." ============================================================================ Centipede, Millipede, Missile Command, Let's Go Bowling.
