Member Function Documentation

frameEnd()

virtual void openmsx::V9990Renderer::frameEnd ( EmuTime::param  time )

pure virtual

Signal the end of the current frame.

Parameters

time	The moment in emulated time the frame ends.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

frameStart()

virtual void openmsx::V9990Renderer::frameStart ( EmuTime::param  time )

pure virtual

Signal the start of a new frame.

The V9990Renderer can use this to get fixed-per-frame settings from the V9990 VDP. Typical settings include:

• PAL/NTSC timing
• MCLK/XTAL selection

  Parameters

  time	The moment in emulated time the frame starts.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

getPostProcessor()

virtual PostProcessor * openmsx::V9990Renderer::getPostProcessor ( ) const

pure virtual

See V9990::getPostProcessor.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

renderUntil()

virtual void openmsx::V9990Renderer::renderUntil ( EmuTime::param  time )

pure virtual

Render until the given point in emulated time.

Parameters

time	The moment in emulated time the frame ends.

Implemented in openmsx::V9990DummyRenderer.

reset()

virtual void openmsx::V9990Renderer::reset ( EmuTime::param  time )

pure virtual

Re-initialise the V9990Renderer's state.

Parameters

time	The moment in emulated time this reset occurs.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

setColorMode()

virtual void openmsx::V9990Renderer::setColorMode ( V9990ColorMode  mode, EmuTime::param  time  )

pure virtual

Set color mode.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

setDisplayMode()

virtual void openmsx::V9990Renderer::setDisplayMode ( V9990DisplayMode  mode, EmuTime::param  time  )

pure virtual

Set screen mode.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateBackgroundColor()

virtual void openmsx::V9990Renderer::updateBackgroundColor ( int  index, EmuTime::param  time  )

pure virtual

Set background color.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateDisplayEnabled()

virtual void openmsx::V9990Renderer::updateDisplayEnabled ( bool  enabled, EmuTime::param  time  )

pure virtual

Informs the renderer of a VDP display enabled change.

Both the regular border start/end and forced blanking by clearing the display enable bit are considered display enabled changes.

Parameters

enabled	The new display enabled state.
time	The moment in emulated time this change occurs.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updatePalette()

virtual void openmsx::V9990Renderer::updatePalette ( int  index, byte  r, byte  g, byte  b, bool  ys, EmuTime::param  time  )

pure virtual

Set a palette entry.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateScrollAX()

virtual void openmsx::V9990Renderer::updateScrollAX ( EmuTime::param  time )

pure virtual

Set scroll register.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateScrollAYLow()

virtual void openmsx::V9990Renderer::updateScrollAYLow ( EmuTime::param  time )

pure virtual

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateScrollBX()

virtual void openmsx::V9990Renderer::updateScrollBX ( EmuTime::param  time )

pure virtual

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateScrollBYLow()

virtual void openmsx::V9990Renderer::updateScrollBYLow ( EmuTime::param  time )

pure virtual

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.

updateSuperimposing()

virtual void openmsx::V9990Renderer::updateSuperimposing ( bool  enabled, EmuTime::param  time  )

pure virtual

Change superimpose status.

Implemented in openmsx::V9990DummyRenderer, and openmsx::V9990PixelRenderer.
