This class implements the AY-3-8910 sound chip.
Definition: AY8910.hh:21
This class keeps track of which bytes in the Ram have been written to.
Definition: CheckedRam.hh:28
const byte * getReadCacheLine(word start) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
void serialize(Archive &ar, unsigned version)
byte readIO(word port, EmuTime::param time) override
Read a byte from an IO port at a certain time from this device.
ColecoSuperGameModule(const DeviceConfig &config)
void writeIO(word port, byte value, EmuTime::param time) override
Write a byte to a given IO port at a certain time to this device.
byte peekMem(word address, EmuTime::param time) const override
Read a byte from a given memory location.
byte * getWriteCacheLine(word start) const override
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for writing.
byte readMem(word address, EmuTime::param time) override
Read a byte from a location at a certain time from this device.
void reset(EmuTime::param time) override
This method is called on reset.
byte peekIO(word port, EmuTime::param time) const override
Read a byte from a given IO port.
void writeMem(word address, byte value, EmuTime::param time) override
Write a given byte to a given location at a certain time to this device.
