Member Function Documentation

frameEnd()

void openmsx::V9990PixelRenderer::frameEnd ( EmuTime::param  time )

overridevirtual

Signal the end of the current frame.

Parameters

time	The moment in emulated time the frame ends.

Implements openmsx::V9990Renderer.

frameStart()

void openmsx::V9990PixelRenderer::frameStart ( EmuTime::param  time )

overridevirtual

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.
