Member Function Documentation

◆ getReadCacheLine()

const byte * openmsx::RomPlayBall::getReadCacheLine ( word  start) const
overridevirtual

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for reading means the data may be read directly from the buffer, thus bypassing the readMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Reimplemented from openmsx::RomBlocks< BANK_SIZE_ >.

Definition at line 43 of file RomPlayBall.cc.

References openmsx::RomBlocks< BANK_SIZE_ >::getReadCacheLine(), and openmsx::CacheLine::HIGH.

◆ getWriteCacheLine()

byte * openmsx::RomPlayBall::getWriteCacheLine ( word  start)
overridevirtual

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for writing.

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for writing means the data may be written directly to the buffer, thus bypassing the writeMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Reimplemented from openmsx::MSXRom.

◆ peekMem()

byte openmsx::RomPlayBall::peekMem ( word  address,
EmuTime::param  time 
) const
overridevirtual

Read a byte from a given memory location.

Reading memory via this method has no side effects (doesn't change the device status). If save reading is not possible this method returns 0xFF. This method is not used by the emulation. It can however be used by a debugger. The default implementation uses the cache mechanism (getReadCacheLine() method). If a certain region is not cacheable you cannot read it by default, Override this method if you want to improve this behaviour.

◆ readMem()

byte openmsx::RomPlayBall::readMem ( word  address,
EmuTime::param  time 
)
overridevirtual

Read a byte from a location at a certain time from this device.

The default implementation returns 255.

◆ reset()

void openmsx::RomPlayBall::reset ( EmuTime::param  time)
overridevirtual

This method is called on reset.

Default implementation does nothing.

◆ writeMem()

void openmsx::RomPlayBall::writeMem ( word  address,
byte  value,
EmuTime::param  time 
)
overridevirtual

Write a given byte to a given location at a certain time to this device.

The default implementation ignores the write (does nothing).
