Known to exist "CMM Rev 1.03" (without Let's Go Bowling) Let's Go Bowling is actually a completely new game by Cosmodog, not a port or prototype of an old Atari game. TODO: - program banking; - finish video emulation; - inputs; - sound; - NVRAM (EEPROM) at U8 or U11 on PCB - driver probably needs rewriting, at least the i/o part; - Is the W65C02S the same as the 65SC02 core or are there any extra Op-codes & addressing modes? 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.
